ADO-MICRO Small Diameter Carbide Drill

The OSG ADO-MICRO drills from the A Series are small diameter carbide drills with oil hole ('coolant through') with efficient and stable performance for small diameter deep-hole drilling.

The ADO-MICRO line-up has features that enable outstanding chip evacuation performance with extended flutes and removed margin ends, so chips are discharged from the tip of the tool through the extended flute geometry, and then discharged  at the end of the margin, avoiding the accumulation of "micro sludge" around the outer periphery of the tool, therefore avoiding abrupt tool breakage.

Also, greater coolant flow achieve by OSG hollow shank design further improves chip evacuation.

Features

New flute geometry avoids "micro sludge" accumulation

Hollow shank for coolant further improves chip evacuation.

Double margin design enable performance even in deep-hole applications
