31/32-inch HSS KFD drill bit for heavy-duty drilling
This 31/32-inch high-speed steel drill bit uses a Killer Force design with a heavy-duty split point for accurate starts. The 1/2-inch reduced shank fits standard drill chucks while the 3-flat shank prevents slipping under high torque. It suits metalworkers and maintenance crews drilling large holes in tough materials.
Thermals noise and power draw in normal use
As a non-powered cutting accessory the bit generates no electrical noise or power draw. Heat produced during drilling depends on the host machine speed feed rate and workpiece material rather than the bit itself. Proper lubrication and cutting speed keep temperatures manageable.

Questions about this item
How do I install the 31/32in HSS drill bit with its 1/2in 3-flat shank and what step is often missed?
Insert the three-flat shank fully into a 1/2in chuck, align each flat with a jaw, then tighten firmly; the step often missed is confirming all three flats seat evenly so the bit runs true.
What maintenance or replacement will the 31/32in KFD drill bit need later?
Resharpen the heavy-duty split point when cutting slows, and replace the bit once the high-speed steel flutes wear down to the 3in flute length or the reduced shank shows damage.
