SCI 21-22 General Catalog

MultiDrill Series MDM Type

■ General Features ● Newly developed oil hole shape with excellent cooling performance achieves longer tool life. ● Effective cooling of the cutting edge created through fluid analysis. Reduces adhesion breakage. ● Chip control and work hardening problems resolved, all in one. ● Outstanding stability in machining of stainless steel and exotic alloys.

J

■ Features and Applications ● Greater discharge of coolant for effective cooling of the cutting edge.

*Suitable for drill diameters of ø4.1 or larger

Newly developed bean-shaped oil hole supplies coolant on cutting edge for effective cooling of the cutting edge
