The Burraway® features a replaceable and inexpensive cutting blade which can be adjusted to control the amount of edge break for consistent results from part to part.
The tool can remove feather edges or heavier burrs, on both sides of the hole, working from one side only.
The Burraway® can be used in fixed spindles or in portable power tools – no need for complicated fixturing, and no special operator skills are required.
The BURR-OFF® operates on the same basic principle as the BURRAWAY®, but is designed for high-production, automated deburring operations. The open-slot design of the “clothespin tool” allows chips to clear easily, which makes the tool ideal for automatic equipment and multi-spindle machines. Just like the Burraway, the Burr-Off deburrs the front, back, or both sides of holes in one fast pass.
The BURR-OFF® is a simple one-piece construction the integral cutting edges can be altered upon request for front or back-cutting only.
The SEDT tool utilizes the same operating principle as the proven Burraway and Burr-Off products. SEDT is designed primarily for the deburring of holes in both angled and elliptical surfaces while also applicable to holes in flat surfaces.
SEDT cutters are carbide with TiN coating as standard. SEDT cutters are crowned and polished on the top surface to insure that the cutter will not mar the inside surface of the hole. SEDT cutters are replaceable and cutter pressure is adjustable without having to remove the tool from the machine.
The MICRO-LIMIT is a precision depth-control countersinking tool. The tool consists of a drive with a piloted countersink and a depth control adjustment feature.
The tool is pre-set to the desired depth of cut. The selected setting is locked in for accurate and consistent results from part to part.
The pilot is engaged in the hole. A stop collar seats on the face of the workpiece; the tool advances to countersink the hole to the desired depth.
The Micro-Limit drive is designed and built for rugged production work. The thrust load is taken up on ball bearings through a hardened steel stop collar. The drive shaft rides on needle bearings. This design makes our drive the longest lasting in the industry.
Three drive models cover a wide range of hole sizes. Adjustment is in increments of .001 inch (.025mm).
The ELLIPTI-BUR® is designed for deburring irregular hole surfaces, such as those which are generated by drilling into curved surfaces, or by drilling at an angle. The ELLIPTI-BUR enables the user to perform these difficult deburring operations quickly and accurately, and without jigs, fixtures, or special operator skills.
As the pilot of the tool is located in the hole, the tool is seated and centered. As the tool is advanced, the pilot is forced into the tool body against the shank spring, and the blade comes into contact with the edge of the hole. As the tool continues to advance, the pilot is further pressed into the body and the blade is driven into the workpiece.
The blade remains free to react to the irregular surface geometry of the hole, allowing for both radial and axial displacement- radial displacement resulting from the elliptical shape of angularly-drilled holes, and axial displacement (“rise and fall”) from the saddle shaped configuration of holes drilled in cylindrical surfaces.
The NOBUR® Tool is a manually actuated deburring and chamfering tool for use where production requirements are low. The tool is used on multi-walled parts and on intersecting holes. It will remove severe burrs and will produce non-qualified chamfers. The tool body pilots in the hole to be deburred. A quick-action sliding sleeve extends the retractable, double-edged cutting blade to deburr or chamfer the front, back, or both sides of holes, in one pass of the tool.
Since the tool is manually actuated while the spindle continues to run, there is no “on-off” down time.
The Flipcut™ tool is designed to perform back-spotfacing or back-chamfering operations in one set-up. The cutter extends, with right-hand rotation of the tool, to cut the back spotface or back chamfer. Left-hand spindle rotation initiates positive mechanical closure of the cutter; the closing action is assisted by centrifugal force. When the cutter is fully enclosed within the arbor pocket, the tool can be easily withdrawn from the bore.
The Flipcut™ tool is designed for rugged use on all types of plant equipment and in all kinds of manufacturing
environments. Tools for hole sizes from .312 inch and above (inch program) and tools for hole sizes from 8.00mm
and above (metric program) have internal coolant capability.
Flipcut™ cutters are a brazed carbide design. Steel body absorbs shock. The brazed carbide Flipcut™ cutting edge
dissipates heat, for outstanding cutting performance.
Deburring holes is usually a costly and time-consuming operation. The back sides of holes are particularly difficult, as they are frequently inaccessible with conventional deburring tools.
Cogsdill Tool Products offers you a better way to get rid of those troublesome burrs. BURRAWAY®, BURR-OFF®, and SEDT-SMOOTH EDGE mechanical hole-deburring tools remove burrs on the front, back, or both sides of drilled holes in one pass… fast, easy, and economical solutions for your hole-deburring problems!
Roller burnishing is a surface finishing technique in which hardened, highly polished steel rollers are brought into pressure contact with a softer piece part.
As the pressure generated through the rollers exceeds the yield point of the piece-part material, the surface is plastically deformed by cold flowing of subsurface material.
The result is a mirror-like finish and a tough, work-hardened surface with load-carrying characteristics which make the burnished surface superior to finishes obtained by abrasive metal-removal methods.

CX Machine ~ Versatility

All ductile or malleable metals with hardness up to R/C 40 can be roller burnished. Cylindrical parts of any length, bars, tubing, wire and stranded cable may all be processed with Cogsdill’s self-contained, self-feeding roller burnishing machines. A continuously variable speed drive allows the operator to select the optimum production rate for obtaining the desired size and finish. An adjustable tilt base makes it possible to select the ideal feed angle for automatic or manual loading.

Several sub-assembly options are available to suit various application requirements (see catalog for CX Sub-Assembly Options).

One pass through a Cogsdill CX machine can quickly reduce a 20-40 microinch Ra (0.5 to 1.0 micrometer) ground surface or an 80-120 microinch (2-3 micrometers)(Ra) turned surface to a mirrorlike 5 microinch (.125 micrometer)(Ra) finish or lower. Parts varying in size as much as .005 inch (.127mm) can be burnished to the same low microfinish with the use of an optional pressure control unit (see Versatility section). The roller burnishing process significantly improves bearing surface over other types of finishing processes and is ideal for shafts running in bushings or oil seals.
Work hardening

Machined parts (turned or ground) can be roller burnished to lustrous, mirrorlike finishes. Subsequent plating applications will often be improved as roller burnishing removes surface patterns and blemishes resulting from prior machining operations.
Fast processing

Cogsdill CX machines process parts in seconds. Parts are sized, finished and work hardened in one pass. Cylindrical parts of any length are processed at speeds up to 30 feet/minute (9.14 meters/minute).

Roller burnishing can often eliminate time consuming and expensive finishing operations such as grinding or lapping.The result is better quality parts, produced in less time, at a lower cost.
Cogsdill Roll-a-Finish tools are applied to a wide variety of part configurations, including:
Inside diameters (holes)
Outside diameters (shafts)
Flat surfaces
Spherical surfaces and contours
Fillets (radii at shoulders)
Standard Roll-a-Finish tools are available from stock for inside diameters from .187 to 4.000 inches (4.75 to 101.6mm), and for outside diameters from .062 to 2.000 inches (1.57 to 50.8mm). The tools are easily adjustable over a typical range of .040 inch (1.02mm). Special designs are available for larger and smaller diameters, and for tapers, faces, contours, and virtually any part configuration.

AEX tools are adjustable in increments of .0001 inch (.002mm).
The Bearingizing tool combines roller burnishing with peening action. As the tool is rotated at a high speed the rolls spin, rise, and fall over a cammed arbor, delivering up to 200,000 rapid fire blows per minute to the work surface. The peaks and valleys of the machined surface are compacted into a smooth, hardened, and ultra-fine surface finish.

Special applications and tool designs
KB Knurling Tool
Salvage out-of-tolerance bores or shafts with the two-step KB®
Knurling-Burnishing “scrap saver” process. Worthless scrap or precision part? The KB “Scrap-Saver” process can make the difference. Cogsdill’s KB process is an innovative approach to making the diameter of holes smaller and the diameter of shafts larger. The KB process was originally developed for automotive parts rebuilding industries, where out-of-tolerance bores and shafts on parts that were formerly scrapped are salvaged with the KB process. The process is also applied in original equipment manufacturing.
Shefcut® precision reamers and boring tools are designed to produce accurately sized, extremely straight and round bores with fine surface finishes. Multiple guide pads rigidly support a single, replaceable cutting blade for exceptional stability and alignment. Size control, surface finish quality, and hole geometry are superior, compared to results from conventional reamers and boring tools.

Each tool is designed for a specific cut diameter. Standard and custom tool designs are offered. Also available from Cogsdill: tool holders designed to complement and enhance the performance of Shefcut tools, and Shefcut setting fixtures for fast and accurate tool settings.
Greater Accuracy, Shorter Cycle Time, Lower Cost

Cogsdill Automatic Recessing Tools will save you time and money. Cycle time is reduced from minutes or hours to seconds. The precision is built into the head so that grooves and recesses can be machined with exceptional accuracy and repeatability. The Automatic Recessing head changes the operational direction by 90˚ (i.e., axial spindle motion is converted to radial cutter movement). Recessing operations can be performed on a variety of machines, even on a drill press.
AR Series

Automatic recessing tools, for machining precision internal and external grooves and recesses on virtually any type of machine. The AR Series Automatic Recessing Tool is made up of three basic components: head, cutter, and pilot. The head is usually standard and consists of shank and tool body.

Generating Heads

Cogsdill generating heads are designed to work on machines where the tool slide stroke is controlled by a drawbar. The drawbar can produce finite, accurate movements in the tool slide(s), allowing the head to perform accurate machining operations. Drawbars can either push or pull on the actuator, and may be controlled by CNC, hydraulic, or mechanical action.

Custom-designed top tooling is mounted in qualified holes on the toolslide. Standard inserts are used for most applications. Special head designs and special form cutters are available.

Operations such as boring, turning, facing, chamfering, and form cutting can be easily performed. Generating heads can often be made to perform multiple operations in a single pass – this provides for optimum efficiency and performance in your machining operations.
Nobur® JB Automatic Back-Chamfering Tool

Cogsdill’s ZX Tooling System provides the ultimate solution in terms of productivity, flexibility, and accuracy for machining large parts that require multiple operations. The ZX system can perform a variety of precision machining operations on horizontal boring mills, including:

Boring - Facing - Contouring
Taper Boring - Deep Cavity Boring - Grooving
Back-spotfacing - Chamfering - Bottle Boring

The Cogsdill ZX range of Contouring and Boring tools, allow relatively simple 2-axis CNC programs to perform a variety of machining operations. Part changes can be accommodated quickly and easily with program changes.

Operations that were previously performed manually can be converted to CNC Control, thus improving productivity, accuracy, part to part repeatability and improved surface finish.
ZX Contouring & Facing Head

The Cogsdill ZX Facing/Contouring heads offer the Greatest versatility of all from the Cogsdill ZX Tooling range. These heads have a single tool slide; onto which top tooling is mounted into qualified locating holes. This provides for repeatable set-ups.

With appropriate top tooling, these heads can perform boring, facing, taper boring, radius forming, chamfering, recessing and threading. Large parts can be machined without having to remove the work piece. Internal Coolant is optional.

Perform Lathe-type operations on boring mills
Maximum application flexibility
Large Diameter Range (from 0mm to 1270mm on ZX900)
Accepts industry-standard top tooling components and inserts (Modular tooling packages also available)
Qualified tool location points in tool slide for accurate and repeatable set-ups
Backlash-free operation
Machine Tool Requirements

The ZX™ system requires the use of a horizontal boring mill with a programmable inner spindle that rotates in unison with the outer spindle, or milling sleeve. The axial movement of the inner spindle is converted within the tool into radial cutting stroke for diameter control. Movement of the table, or machine column, on a parallel axis controls the axial location of the cutting edge relative to the part. In most horizontal boring mills, these two axes are referred to as “W” and “Z”.

Controlled inner spindle movement is converted into radial cutter movement
Independently controlled column or table movement parallel to spindle

Operating Principles

The ZX system is comprised of two basic styles of tools:

Facing / contouring heads, featuring a single slide onto which various top tooling can be installed.
Boring / contouring tools, used primarily in boring operations inside parts.

Regardless of head type, a proven actuation mechanism produces radial cutter movement. This sturdy design is based on the “sliding inclined wedge” principle for backlash-free operation; no sloppy gears or bell cranks are used. All parts are hardened and ground for lasting accuracy and durability.
Modular Boring Tool

Modular Boring Tool

Cogsdill ZX Modular Boring Tools (MBT) offer versatility and economy when machining bores, counter-bores, tapers, threads and complex contours inside components over a wide range of diameters. These tools offer the highest cutting speeds and material removal rates available. The MBT Series is available in single-slide (MBT-S) and twin-slide (MBT-T) versions. All MBT tools feature 2:1 actuation ratio for easy programming.

Benefits of Cogsdill MBT Tools:

Broad size range: Each tool has a long tool slide stroke that is supplemented by using different cartridges to cover an even wider diameter range. No need to change the tool slide(s) or remove the head from the machine.
Versatility – performs forward and back boring operations, back counterbores, internal grooves, faces; bottle bores can also be machined.
Bottom-facing capability available for blind bores.
Exceptional concentricity: stepped and tapered bores are machined without tool changes. Concentricity is maintained as the tool slide(s) adjust for various diameters while the tool stays on the same bore centerline.
Twin-slide tools offer balanced cutting forces for high feeds and speeds and high material removal rates.
Internal through-tool coolant is standard.
Fully enclosed actuation mechanism: No chip packing.

• Look for:
Hole Making Applications – primarily high production and high precision, competitively priced parts. Also look for geometrically uniform exterior surfaces.

Think about:
Good finish requirement and possibly tight tolerances
Think about:
Can be used on a variety of machines and materials
Think about:
Better parts in less time at lower cost
Think about:
Reduction of labor content in finished parts: eliminate secondary finishing operations (honing, grinding, polishing, manual deburring, etc.)
a. What to look for: Holes (and shafts or other surfaces) requiring good surface finishes and/or good size control. Work hardened or wear surfaces. Any material (aluminum, steel, stainless, brass) under 50 HRc.
b. What to ask:
 Do you make parts that have seal surfaces, metal-to-metal running contact, close fit, shiny or aesthetically good surface requirements?
 Do you have to achieve a good surface finish on your parts? What? The lower the better.
 What is tolerance you have to hold? The tighter the better.
 Look for surface finish requirements on part prints.
 Do you now grind or hone to achieve this? How long does that take?
c. Features and benefits to promote about Cogsdill burnishing:
 Four primary benefits: Improved surface finish, improved size control, increased surface hardness (5-10%), improved fatigue life (300% or more). See burnishing overview on pages 4-5 of catalog.
 Short cycle time – low RMS surfaces in seconds (down to 4 micro inches).
 Significant cost savings – much less than grinding or honing in much less time.
 Clean process – no material is removed.
 Easy to use and adjust tooling – highly skilled operator not required.
