41/64in Silver & Deming drill bit
This 41/64in high-speed steel drill bit features a reduced 1/2in shank with three flatted surfaces for secure chuck grip. Silver and Deming geometry suits general-purpose drilling in metal, wood and plastic. Surface-treated flutes help clear chips and reduce friction during use.
Reduced shank upgrade for 1/2in chucks
The bit replaces smaller-diameter drills when a 41/64in hole is required and the machine only accepts 1/2in shanks. The jump is worth it when a single large hole eliminates step-drilling or when the flatted shank prevents slippage that round shanks allow.

Questions about this item
What chuck size is needed for the 1/2 reduced shank?
The bit has a 1/2 inch reduced shank so it fits any drill chuck that opens to at least 1/2 inch. The three flats on the shank prevent slipping in a standard three-jaw chuck.
How do you seat the three-flatted shank correctly?
Align each flat with a jaw of the chuck, then tighten firmly. The step people miss is checking that all three flats are fully engaged before drilling.
