High-speed steel Silver and Deming drill bit with a 1/2 in reduced shank for 1-29/64 in holes
This high-speed steel bit features a 1/2 in reduced shank that fits standard drill chucks while delivering a large cutting diameter. The silver and Deming design provides reliable performance for heavy-duty drilling tasks in metal and wood.
Use this bit when a project demands a 1.4531 in diameter hole and your chuck cannot accept a full-size shank. It is not suited for precision work requiring tighter tolerances or for machines limited to smaller-capacity chucks.
Measured against everything we stock in Bits, Hole Saws & Accessory Kits, at today’s prices. Recalculated every night.

The bit has a 1/2 in reduced shank that fits any chuck accepting 1/2 in diameter shanks.
Open the chuck fully, insert the 1/2 in shank completely, then tighten all three jaws evenly so the shank seats flat against the chuck face.
