Item Description
To be used only on CNC machines and routers with automatic feeding.
Using the highest quality sub-micrograin carbide these bits have a special proprietary edge processing system featuring a super high polished cutting edge with a unique “mirror finish” resulting in clean cuts, less chance for chip re-welding, a superior surface finish and a longer tool life. Right hand helix right hand cut.
Specifically designed for a variety CNC machining applications excellent for cutting:
- ALPOLIC® Copper Composite
Material (CCM)
- Alucobond®
- Aluminum
- Aluminum 5052
- Aluminum 6061
- Aluminum Alloys
- Aluminum Composite
Materials (ACM)
- Aluminum Composite Panel (ACP)*
- Alupanel®

- Silver
- Solid Surface
- Titanium Composite Material (TCM)
- Wood
Ideal for industrial applications our spiral ‘O’ flute router bits are manufactured using innovative techniques and materials that yield superior results with each cut and help make aluminum projects less labor-intensive.
Benefits of Mirror-Finish:
- Razor sharp cutting edge
- Effortless chip removal
- Helps prevent chip re-welding
- Extends tool life
- Exceptional cut quality
- Dissipates heat well and prevents melting
Aluminum composite panel (ACP) is a type of ACM flat panel that consists of two thin aluminum sheets bonded to a non-aluminum core. ACPs are frequently used for building facades external cladding insulation and signage. **Durabond is a polyethylene core with 0.3mm colored aluminum sheet on either side pre-finished requiring no decoration.
Warning:** Never attempt to cut ferrous metals with these bits.
Inspect cut quality adjust feed / speed accordingly.
For optimal results and extended tool life use mist lubricant system or air cooling.
Maximum RPM:**35,000.

Need This Tool Customized?
Every machining application is different. If this tool is close to what you need but not an exact fit, General Cutting Tools can help modify it for your specific job, machine, material, or production requirement.
We work with CNC shops, industrial manufacturers, tool rooms, and production facilities to provide tool modifications that improve fit, function, performance, and efficiency. Whether you need a small adjustment or a more specialized cutting tool solution, our team can review your requirements and recommend the best option.
Custom tool modifications can help reduce setup time, improve accuracy, extend tool life, solve clearance issues, and support more consistent production results.
Common Tool Customization Options
Diameter and OD Modifications
We can modify tool diameters to better match your application requirements, including cutting diameter changes, OD modifications, pilot diameter adjustments, step diameters, and shank diameter modifications.
Bore Modifications for Saw Blades
Custom saw blade bore modifications are available for hole diameter changes, pinholes, mounting holes, and keyway cutouts to help match your machine setup and cutting requirements.
Length Adjustments
Tools can be modified for specific reach, clearance, or setup needs. This may include overall length changes, flute length adjustments, reduced neck sections, extended reach designs, or shortened tools for improved rigidity.
Shank Modifications
Shank modifications can help ensure the tool fits properly in your holder, spindle, or machine setup. Common options include shank diameter changes, flats, Weldon flats, reduced shanks, and custom holding requirements.
Radius, Chamfer, and Corner Changes
We can customize corner radius, chamfer angles, edge breaks, and other profile details to meet part print requirements or improve cutting performance.
Step Tool Modifications
For applications that require multiple diameters or operations in a single tool, we can create or modify step tools to help reduce tool changes and improve production efficiency.
Flute and Cutting Edge Adjustments
Depending on the tool and application, flute length, cutting edge geometry, end cutting features, relief angles, and cutting edge shape may be modified to improve chip evacuation, cutting action, and tool performance.
Regrinding and Resharpening
Many cutting tools can be reground or resharpened to restore performance, extend tool life, and reduce replacement costs.
Custom Profiles and Special Forms
For unique part features, we can help provide special forms, custom profiles, custom radii, counterbores, countersinks, keyseat cutters, form tools, and other application-specific tooling solutions.
Material-Specific Tool Adjustments
We can help modify or recommend tooling based on the material being machined, including aluminum, brass, bronze, plastics, stainless steel, hardened steel, cast iron, composites, and other industrial materials.
Have a Drawing, Sample, or Part Print?
Send us your print, sketch, CAD file, photo, tool number, sample, or application details. For the fastest quote, include the material being cut, quantity needed, required dimensions, tolerances, and any machine or holder requirements.
Coating Options
Tool coatings can be selected or added to improve wear resistance, heat resistance, lubricity, and performance in specific materials such as steel, stainless steel, aluminum, cast iron, and high-temperature alloys.
