Long shank type prevents troubles for overhang application.

Do you have any troubles drilling a deep hole?

Have you had any troubles using a long straight drill when long overall length is demanded for preventing collision with workpiece?

High rigidity

Shorter flute length in comparison with conventional long straight drill is used to maintain high rigidity, thereby preventing various troubles.

Stable machining due to optimum design

Better engaging stability

Better engaging stability since the thinning part whose point angle is obtuse becomes smaller.

sdls_03_en.png

Lower cutting force

Lower cutting force since length of cutting edges formed by thinning becomes shorter.

sdls_04_en.png

Better chip disposability

Better chip disposability because the core dia. can be smaller and the chip pocket becomes bigger.

sdls_05_en.png

All-rounder flute geometry which enables to machine wide range of work materials and it is available for both machining center and manually operated machines.
