”Sumi Power Mill”
PWS(-F) Type
Features
Smooth and stable performance under rough milling conditions
Tangentially mounted inserts, offering positive rake angle and unique curved
cutting edge, realize stable and long lasting smooth cutting actions.
Precision 4 cutting edge inserts
The 4 cutting edge inserts offer maximum cost performance.
Less vibration under unstable condition
Optimized variable pitch design of the serrated inserts minimizes vibration
during unstable conditions.
Tough and durable body
Cutter body shows excellent toughness and durability through special steel
and surface treatment.
