7/8 X 1/2 REDUCED SHANK DRILL

SUTTON TOOLS D188-Series Reduced Shank Drills are designed to increase the drilling capacity of drill chucks for large scale boring applications.

These bits feature a blue surface finish which is suitable for ferrous metal drilling applications. The steam oxide finish prevents chip build-up on the cutting edges and reduces cutting friction, especially in low carbon steels.

These drills should be used at low speed (350 RPM or less).
