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 workpiece 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
