3/8 CARVING 3D BALL NOSE ZrN
Item Description
These router bits are made with an extra-long reduced shank section for deeper reach and better chip clearance. Amana Tool®’s Modern Materials Finishing Geometry (MMFG) incorporates high shear, multi-flute and ZrN coating designed for the ultimate combination of finish and tool longevity in aerospace materials. Modern-day materials present challenges to the fabricator, using these special multi-flute edge tools featuring ZrN ceramic coating addresses these challenges with a winning geometry combination.
The simultaneous 3 axis motion with the appropriate software allows full 3D capability that provides sign and 3D model makers the ability to work with any material.
Specially designed for 2D and 3D CNC profiling and carving in plastic, aluminum & wood with CNC machines. The high-shear ball nose tips cut smooth 2D and 3D contours with reduced stepping while the proprietary ZrN coating (applied by the physical vapor deposition coating process) provides high resistance to wear, sharper cutting edges, extended tool life and less friction and heat buildup. Some of Amana Tool carving tools, as you can appreciate have a very small diameter therefore any material chip-loads need to reflect that small size. It can however withstand RPM’s up to 60,000 RPMs. A directed air-blast to keep chips away along with cooling the tool and work piece are always welcome.
Tools are manufactured with high balance that allows them to run up to 60,000 RPMs. Adjust your chip load and feed rate accordingly.

Benefits of Zirconium Nitride (ZrN) Coating
- Creates a harder and tougher cutting edge allows for a prolonged cutting edge life and helps to prevent the build-up of material in the flutes while cutting
- Have the tendency to run/spin much faster than an uncoated tool
- Optimized flute geometry and low Total Indicated Runout (TIR) guarantees clean cuts, essentially eliminates sanding and reduces chatter (where the machine or work piece vibrates) under high chip loads (when used with low TIR spindles)
- High flute volume supports high feed rates and chip loads
- High aspect ratio for single pass deep-reach cutting
- Flute geometry optimized for cutting sign foam, sign board, hardwoods, thermoplastics and phenolic composites
Milling Plastics:
In a milling application, all plastics tend to behave differently so attention must be paid first and foremost to heat input, as that greatly impacts surface finish and chip control.
Suggested starting spindle speed might be 18,000 RPM, there needs to be some experimenting on the part of the programmer to best find an acceptable finish.

Amana Tool
Amana Tool® is an industry leader for over 40 years specializing in industrial quality solid carbide, insert carbide and carbide-tipped cutting tools for the woodworking, plastics, aluminum, composite and metal industry. They provide many solutions for manufacturers, fabricators, display and cabinet professionals as well as hobbyists. Amana Tool’s full line of industrial-quality cutting tools includes saw blades, router bits, shaper cutters, boring bits and much more.
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.
