Description
Drilling a hole, switching to a tap, then switching to a countersink wastes time and bits. Each bit in this set does all three in one pass — drill, tap, and countersink in a single operation. High-speed steel construction cuts through sheet metal, plastic, copper, and brass with a 1/4″ hex shank that works with the included quick-change adapter for fast bit swaps.
Thirteen pieces covering 6 SAE and 6 metric sizes, plus the adapter. One case handles the threading work that used to take three separate tools.
3-in-1 Operation Each bit drills, taps, and countersinks in a single pass. No tool changes, no re-chucking, no alignment issues between operations.
High-Speed Steel Durable HSS construction ensures sharp cutting edges and minimal wear through repeated use on metal, plastic, and other materials.
Quick-Change Adapter 1/4″ hex shank bits work with the included quick-change adapter for fast, effortless bit swaps. Tapered ends prevent overtapping and minimize oversized holes.
