[HRC89 Hardness] HSS-Co M35 steel step drill has been treated with titanium nitride on the surface and has a hardness of HRC89. Outstanding sharpness than ordinary steel step drills. Abrasion resistant and heat resistant, reducing heat generated during friction
For Stainless Steel: An essential tool for drilling stainless steel, iron plate, 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 】TiAIN Titanium Nitride increases surface hardness up to 89 degrees and withstand loads in high-speed rotations. When drilling, the A1203 forms a hard protective layer to improve the drill's high temperature and grinding resistance, making it ideal for high-speed drilling
Scope of application: High stability and long service life are noticed. The step drill enlarges the holes in order from small to large holes to allow for multiple sizes and enlargement of holes. In addition, the shape of the shaft is hexagonal shaft, so it be used with impact drivers, electric drills, and charging drills
Drilling Dimensions: 0.2 - 0.8 inches (4 - 20 mm) (9 levels) (4, 6, 8, 10, 12, 14, 16, 18, 20)
