XR90 Face Mills for Diamond Inserts are a Multi-purpose positive/negative geometry cutter that optimizes horsepower utilization. This allows you to get the most from your low horsepower machines. Also, this cutter is designed to perform at accelerated spindle speeds. To extend its application range (value), the pockets are designed to accept either the round or the octagon inserts. Non-rhythmic insert spacing counters harmonic vibration (chatter). Inserts are available in PCD
