Bored through about twenty studs for a garage shelf and the single-flute design really does spit the sawdust out fast, barely had to clear the hole. The 9-inch length gave me plenty of reach without any wobble, and it stayed sharp through the whole batch.

Bored a dozen holes through some oak shelving this weekend and the single-flute design kept pulling sawdust out instead of clogging up like my old twist bits. The 9-inch length gave me plenty of reach for the deeper passes without needing to reset.

The chip clearance on these is genuinely impressive—I drilled several deep holes in oak and the single-flute design kept pulling sawdust out without me having to back the bit out constantly. The 9-inch length gave me plenty of reach for thicker stock, and they stayed sharp through the whole session.
