Step drill bit Wolfcraft 2933000 Ø9.5 mm, 1 pc, polybag

The Wolfcraft step drill bit 2933000 Ø9.5 mm is a single-piece accessory intended for use with drills to make stepped holes for concealed fastenings in wood and to enlarge or create progressive hole sizes in thin sheet materials and plastics. Supplied as one drill bit in a polybag, it is compatible with the undercover jig set (4642000) and includes a depth stop for precise control of drilling depth.

Advantages

The step drill bit combines a pointed tip that pre-drills a guide hole for the screw thread with a larger second step that creates a countersink for the screw head, enabling concealed fastenings without changing tools. The included depth stop ensures consistent drilling depth and repeatable results. Its single-piece design simplifies handling and reduces setup time for installers and DIY users.

Usage recommendations

Use appropriate drilling speed and steady feed pressure for the material being worked; for metal sheets and plastics use lower speeds and for wood moderate speeds. Always wear eye protection and follow drill manufacturer safety instructions. For repeatable concealed fastenings in wood, combine this step drill bit with the undercover jig set 4642000.
