✨CLEAN & BURR FREE HOLES: You’ve probably used step drill bits before, and if not, you should consider giving them a try. Step drill bits are incredibly useful for drilling clean holes in sheet metal, thin plastic, and other such materials. The way step drill bits shear the edges of a hole as they cut, they leave clean and nearly burr-free holes.

✨HSS STEEL CONSTRUCTION: High-speed steel construction for longer cutting edge life, even at extreme temperatures.

✨TITANIUM COATING: This titanium-coated step drill bit provides good resistance to heat, corrosion, and rust.

✨AUTOMATIC CENTER PUNCH: Provides an automatic, impact-resistant, spring-loaded impact when pressed against the surface. The adjustable cap regulates the impact force.
