  • Product typeDrill Accessories

  • Heavy-duty high-speed steel resists wear in tough materials

3/4" HSS Killer Force Drill Bit

The Drill America 3/4in HSS 1/2in Shank KFD drill bit is built for heavy-duty drilling in metal. Its high-speed steel body and reduced 1/2in shank allow use in standard drill chucks. A heavy-duty split point reduces walking and starts holes cleanly without a centre punch. The three-flat shank prevents spin-out under high torque.

Suited for high-torque metalwork.

Machinists and fabricators drilling 3/4in holes in steel or iron will value the split-point accuracy and anti-slip flats. The 1/2in reduced shank fits common 1/2in-capacity drills. Builders needing a solid 3/4in shank for larger chucks or those drilling primarily wood, masonry or non-ferrous materials should look at other bit designs.

Questions about this item

How hot does the 3/4in HSS drill bit get during continuous heavy-duty drilling?

High-speed steel handles heat well, but prolonged use at high speed will raise temperature; use cutting fluid and allow cooling periods to protect the 3-flat shank and split point.

What chuck size is needed to hold the 1/2in 3-flat shank on this drill bit?

A 1/2in capacity drill chuck is required to grip the reduced shank; the three flats prevent slipping in the jaws during high-torque applications.
