5-piece step drill bit set with automatic center punch and twist drill bit – double slotted conical cut, titanium coating

【AUTOMATIC CENTER】: The automatic center provides a powerful, spring-loaded strike on the cap; its brass body features a deeply knurled surface for a non-slip grip. The protective aluminum case allows for convenient storage and easy transport.

【DOUBLE CUTTING BLADES & THREE-SIDED SHAFT】: The double cutting blades and X-shaped opening ensure faster and more consistent cutting; the three-sided shank design prevents the chuck from slipping; With minimal pressure, these sets cut wood, sheet metal, steel, and other surfaces.

【COATING AND TITANIUM】: High-speed steel makes the step drill bit set particularly durable, while the titanium coating allows for effortless cutting of sheet steel, aluminum, copper, plastic, wood, and many other types of sheet metal.

【TIME-SAVING】: Thanks to the various step sizes, you can drill or enlarge different holes with just one drill bit without constantly having to change bits. The size is laser-engraved, allowing for precise drilling and preventing wear on the drill bit even with extended use.
