Milling Cutters Cutting length (mm)Cutting force (N) Cutting Force (N) ”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.
