AMS-148 4-Pc Solid Carbide Up-Cut Spiral 2D/3D Carving Ball Nose ZrN Coated CNC Router Bit Set, 1/4 Inch Shank, Includes 1/32, 1/16, 1/8 & 1/4 Diameters.

Solid Carbide Up-Cut Spiral 2D and 3D Carving Ball Nose (Conical Ball) Zirconium Nitride (ZrN) Coated CNC Router Bit Set

Specially designed for 2D and 3D CNC profiling and carving in plastic aluminum & wood with machines such as "i-Carver" CNC Shark® ShopBot® Datron & Carvewright™. 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 & heat buildup.Applications:

A perfect bit for 3D carving

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
