1-11/32in HSS reduced-shank drill bit
This high-speed steel Silver and Deming drill bit has a 1-11/32in cutting diameter and a 1/2in reduced shank that fits standard 1/2in drill chucks. It is suited for machinists and maintenance technicians who need to enlarge existing holes in metal.
Decimal size 1.3438in determines fit
The bit’s decimal equivalent is 1.3438in, so the workpiece must already have a pilot hole at or near that size. Buyers who need a smaller starting diameter or a larger shank for a different chuck will need a different bit.

Questions about this item
What does the 1.3438 decimal size mean when the bit is chucked in a drill?
The 1.3438 inch diameter is the exact cutting width; the reduced 1/2 inch shank fits standard drill chucks while the larger body drills a 1-11/32 inch hole.
How does the 1/2 inch reduced shank limit the bit in use?
The 1/2 inch shank fits common three-jaw chucks, but torque must stay within the chuck's grip capacity to prevent slipping during heavy drilling.
