HSS WITH 5% COBALT: Durable, Higher Heat & Abrasion Resistance.

PRECISE 135° SPLIT POINT & TWIST DESIGN: Prevent walking, clear chips and particles faster.

HSS Titanium Coating - High speed steel along with titanium coating ensures outstanding durability and sharpness, can reduces the friction, runs cooler.

Meet Your Demands - With the step drill bits we offered, you can process different kinds of diameter holes, which greatly saves you a lot of trouble.Great for steel sheets/ aluminum sheets/ copper/ plastic/ wood board and many other types of sheet metal with ease countersunk. Suitable for Home DIY, and General Building/ Engineering Use.

Design - The split point tip is at 118 degrees to increase the wear resistance. The two flute design provides a smoother cutting, allows the material particles escape easily for a much more clean drilling operation.
