Feature

●[HRC89 Hardness] HSS-Co M35 steel step drill has been treated with titanium nitride coating 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 Coating】TiAIN Titanium Nitride coating increases surface hardness up to 89 degrees and can withstand loads in high-speed rotations. When drilling, the A1203 forms a hard protective layer to improve the drills 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 can be used with impact drivers, electric drills, and charging drills
●Set of 2: 4-12 mm (9 Tiers) (4,5,6,7,8,9,10,11,12). 4-20mm<9 Tier> (4,6,8,10,12,14,16,18,20) Includes a step drill storage case


Description

Step DrillStep Drill

[Note]

Because it is sharp, please use it vertically.

Regular ironwork drills temporarily heat resistant with titanium coating, but the blade will not wear out and cut before the blade is hot and the result is a higher coefficient of wear and burn.Stainless steel is harder and more sticky than ordinary iron, so when used for work, we recommend Cobalt Hiss (HSS-CO) that is harder and more resistant to wear and tear.
