Detailed Product Description


Subland drill bits,step drill bits,taper shank

 

A Subland Drill is two drills with different diameters built into one tool. Each diameter has its own characteristics and geometry and remains that way for the life of the tool. Even after re-sharpening the Subland Drill maintains the original size and concentricity between diameters and shank. A Subland Drill is perfect for drilling two diameter holes in one pass.
