1-17/64in Silver and Deming Drill Bit

This 1-17/64in Silver and Deming drill bit is made from high-speed steel with surface-treated flutes for general-purpose drilling. It suits machinists and maintenance technicians who need a large-diameter hole in metal, wood or plastic using a standard 1/2in chuck.

1/2in reduced shank fits common chucks

The 1/2in reduced shank allows the bit to be secured in any drill press or hand drill with a 1/2in capacity, removing the need for a larger chuck. Buyers whose equipment only accepts smaller shank diameters will need a different bit or an adapter.

Questions about this item

What hole size will the 1-17/64" bit actually produce in steel?

The bit cuts a nominal 1.2656" diameter hole; actual size in steel depends on drill rigidity, feed rate and coolant, but expect a result within standard HSS tolerance for this diameter.

How does the 1/2" reduced shank limit the bit in a drill press?

The 1/2" shank fits any chuck that accepts 1/2" capacity, so the bit is capped by the machine's chuck size rather than the shank itself; ensure the press spindle and chuck are rated for the 1.2656" cutting diameter.
