【MULTI-SIZE】This professional stepper drill bit can accurately drill holes of various sizes, from 5mm to 35mm, allowing you to complete large holes simultaneously without changing the drill bit or the positioning tool.

【QUALITY MATERIALS】Made of classic high-speed steel with a titanium coating, this drill bit offers proven performance and durability for drilling holes in plastics, wood, aluminum, copper, stainless steel, and many other types of sheet metal. Titanium alloy drill bits are particularly suitable for drilling copper and aluminum parts, die steel, spring steel, cast iron, iron, and other metal materials.

【PRECISION POSITIONING DRILL BUTTON】When pressed against the surface, it generates a powerful, spring-loaded, automatic impact force. An adjustable cap allows you to regulate the impact force.

The knurled surface of the brass body is highly non-slip, providing precise positioning points without worrying about deviations. 【EASY DRILLING】The twin-blade design offers faster, smoother drilling at low pressure and high steps, so you won't experience stagnation or resistance, with optimal speed and accuracy. 【LASER ENGRAVING】The size is laser-engraved into the metal, so it won't wear down even with repeated use, facilitating precise drilling.
