Feature

●Set of 4: 0.16 - 1.3 inches (4 - 32 mm) / 15 steps (length 4.0 inches (102 mm), 0.4 - 0.8 inches (4 - 20 mm), 9 steps (length 2.6 inches (68 mm), automatic center punch set includes a bonus step drill storage pouch. Can be drilled in various sizes
●(HSS Steel Material) Uses high speed steel (HSS-4241) and the surface is coated with titanium coating, which is harder than regular step drills and has excellent sharpness. Reduces heat produced during friction
●Spiral Drill: The spiral grooves allow the shavings to be removed upward. Reduces pressure during cutting and cuts smoothly. Compared to ordinary drills drills, the blade is beneficial to reduce the phenomenon of breakage and has a long service life
●[Range of application] The step drill is expanded in order from small holes to large holes, so you can adjust the opening of multiple sizes and enlarging holes. In addition, the universal hexagonal shaft can be used with impact and electric screwdriver drills. Millimeter display improves work accuracy
●Wide range of uses: Suitable for drilling thin iron plates, aluminum plates, wood, vinyl, resin, etc., enlarging the lower hole, chamfering, deburring, etc. Compatible with drilling of soft metals within 0.1 inch (3 mm) but not compatible with stainless steel and plate thick metals. For stainless steel plates, we recommend a more professional cobalt high speed steel drill
