【HIGH-QUALITY MATERIALS】The step drill bit made of high-hardness HSS 6542 is perfect for metals and can even drill through stainless steel up to a thickness of 1.5 mm. This is not possible with other, lower-quality HSS 4241 drill bits on the market.

【VERSATILE APPLICATIONS】The step drill bit is versatile and can be used for metal, stainless steel, aluminum, copper, plastic, plexiglass, wood, and other materials.

【15 STEPS】With one step drill bit, you can drill holes with a diameter of 4 to 32 mm. (4 mm/6 mm/8 mm/10 mm/12 mm/14 mm/16 mm/18 mm/20 mm/22 mm/24 mm/26 mm/28 mm/30 mm/32 mm).

【10 MM TRIANGLE SHAFT】The step drill bit is compatible with all common cordless screwdrivers, hand drills, and drill presses. The reinforced 10 mm handle reduces the risk of breakage.

【INSTRUCTIONS FOR USE】When drilling metal and other very hard materials, the step drill bit can become hot and produce smoke. Adding coolant or water will continuously lower the temperature, extending the life of the step drill bit. Otherwise, it may soften and discolor. The larger the drill hole diameter, the lower the speed should be to protect the cutting edge.
