Solid Carbide 2D and 3D Carving Flat Bottom Zirconium Nitride (ZrN) Coated Router Bits
46578 CNC 2D and 3D Carving Flat Bottom 0.10 Deg Straight Angle x 1/4 Dia x 3/4 x 1/4 Shank x 2-1/2 Inch Long x 3 Flute Solid Carbide ZrN Coated Router Bit
Specially designed for 2D and 3D CNC profiling and carving in plastic, aluminum & wood with CNC machines. The high-shear flat bottom 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
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.
