The Drill America KFD3F Series 1-1/4″ reduced shank drill bit is designed for users who need a larger cutting diameter while still fitting a 1/2″ chuck. Made from M1 high speed steel and finished in black and gold, it’s a practical pick for metal drilling jobs where consistent starts and a solid chuck grip matter.

The 135° split point tip helps the bit self-center and reduces thrust, minimizing “walking” compared with a conventional 118° point. The 3-flat 1/2″ reduced shank provides an extra-secure hold in the chuck, which is especially helpful when stepping up to a 1.25″ cutting diameter.
With a common flute and overall length (3″ flute length, 6″ overall length), it’s also convenient for tool changes with minimal adjustment.
