MD Self Feed Drill Bit for ...

Product details

A self feed bit carries a screw point at its tip, so once the point bites it draws itself through framing rather than waiting to be pushed. Part 822 measures 2-9/16 inches across, which is the size MD specifies for boring the stud and plate holes a central vacuum pipe run has to pass through.

MD names a hole hog drill as the tool this bit belongs in, and that is not incidental advice. A cutter this wide loads a light-duty drill hard enough to stall it or wrench it sideways, and the screw tip keeps drawing forward even after the motor bogs down, so a firm two-handed grip matters more here than with an ordinary twist bit.

Chips pack into the flutes on a long run of framing. Clearing them between holes keeps the cutting edges biting instead of burnishing and scorching their way through the last few studs of the day.

  • Part: self feed drill bit, part number 822
