MEL Type Suitable for exotic metals such as stainless steel, soft steel, gray cast iron, and low rigidity setups. Overlap DEX Coating Thinning
Large thinning angle D
Excellent cutting edge design for stainless steel and soft steel
Large thinning angle prevents breakage at the convex R-profile portion, particularly when drilling
soft steel and it also reduces breakages caused by adhesion when drilling stainless steel.
D Improved chipping resistance in cast iron
Small edge treatment Better edge sharpness at the peripheral edge prevents chipping around the hole openings when drilling cast iron. Sharp peripheral cutting edge
- 25% Reduction in Cutting Force (Thrust Force)

Note: Where machine and work clamp rigidity are good, conditions may be increased up to the maximum. (*) Inquire about drills specifically For 8D and 12D drills, please use feed rates stated within the ( ). for aluminum alloy. Before drilling 8D and 12D holes, a guide hole of similar diameter must be made.
