✔️ 9-hole set, 6.4-19.1 mm (1/4-3/4 in), 3/8 in hex shank

The two straight flutes promote efficient chip removal for cleaner cuts, while laser-etched size markings help you quickly identify the correct hole size. The 3/8-inch hex shank provides a secure grip in the drill chuck, and the fast-starting non-walking tip starts cuts precisely. This 9-hole set covers sizes from 1/4 in to 3/4 in (6.4-19.1 mm) and works on steel up to 16 gauge, plus wood, plastic, and aluminum.
