STEP DRILL 4-12mm

The 4–12mm Step Drill Bit is ideal for clean, precise drilling in sheet metal, aluminium, plastic, and fibreglass—no pre-drilling required. Each step is designed to cut smoothly, while the following step automatically deburrs the previous hole for a neat finish.

Built from durable M2 High Speed Steel (HSS), this bit offers excellent strength, heat resistance, and long-term performance. The spiral flute design reduces vibration for greater control, and the three-flat shank ensures a secure grip in standard 3-jaw chucks.
