Feature

●HRC89 Hardness: HSS-Co M35 steel step drill has a titanium coated surface to HRC89. Outstanding sharpness than ordinary steel step drills. Reduces heat produced during friction
●For Stainless Steel: An essential tool for drilling stainless steel, thin iron plates, aluminum plates, wood, vinyl, resin, etc., for household DIY, enlarging the lower hole, chamfering, deburring, etc. This is a daily item for home or work
●"Industrial Grade TiAIN Coating" TiAlN coating surface forms an A1203 which forms a hard protective layer when punctures, improving the high temperature and grinding resistance of the drill, making it ideal for high-speed drilling
●Scope of application: The step drill extends the holes in order from small holes to large holes, so you can modify the enlargement of multiple sizes and holes. In addition, the shape of the shaft is hexagonal shaft, so it can be used with impact drivers, electric drills, and charging drills
●Set of 2: Set of 2 (4 - 20 mm) 9 tiers (length 2.0 inches (50 mm), 0.2 - 0.5 inches (46 mm)), 9 steps (length 1.8 inches (46 mm)), and 1 step drill storage pouch
