Drill America 47/64" HSS KFD Drill Bit
This 47/64 inch high-speed steel drill bit features a 1/2 inch shank with three flats for secure chuck grip. The Killer Force design includes a heavy-duty split point that reduces walking and improves penetration in tough materials. Flute length is three inches and overall length is six inches for deep-hole work. Decimal equivalent is .7344 for precise sizing.
Suits metalworkers needing large reduced-shank bits
Machinists and fabricators drilling 47/64 inch holes in steel or cast iron will appreciate the split-point start and rigid shank. Users requiring smaller diameters, metric sizes, or carbide-tipped cutting edges should select a different bit. Those without a 1/2 inch capacity chuck cannot use this shank.

Questions about this item
How do I install the 47/64in HSS drill bit with its 1/2in 3-flat shank, and what step is often missed?
Insert the 3-flat shank fully into the chuck and tighten each flat against a jaw so the bit cannot spin; the step many miss is checking that all three flats seat evenly before drilling.
What maintenance or replacement will the 47/64in KFD drill bit need later?
Resharpen the heavy-duty split point when cutting slows, and replace the bit once the 3in flute length wears down or the 1/2in reduced shank shows damage.
