SEC-Multi Drill, SMDT-MEL Type

[Features]
・ A highly precise and high-strength head replacement drill bit with radial serrations.
・ Uses a special surface treatment that excels in abrasion resistance and rust prevention.
・ By replacing the head, you can always use it with a new cutting edge, contributing to productivity, cost reduction and tool management.
・ The re-polishing allowance is secured at about 1.5 mm to 3 mm, which further reduces the tool cost.
・ The large thinning angle solves the defect of convex radius part peculiar to mild steel. With SUS material, welding defects at various parts are reduced.
・ It improves the cutting performance of the outer periphery and prevents the occurrence of edge chipping at the cast iron hole exit.
[Applications]
・ Ideal for mild steel, gray cast iron, low rigidity equipment and difficult-to-cut materials such as stainless steel.
