ROGAPER 3PC Step Drill Bit Set, High Speed Steel Features
-
HSS Titanium Coating: Our high-speed steel drill bits, fortified with a titanium coating that makes the drill bit harder than a typical HSS bit, can reduce the friction drill, and perform well in heat, corrosion, and rust resistance.
-
Unique Design - The tip bifurcates at 118 degrees for added wear resistance. The two-groove design provides a smoother cut, allowing material particles to escape easily for a cleaner drilling operation.
-
Meet Your Needs - With the step drill bits we offer, you can machine holes of different diameters. Ideal for plastic/wood/board/soft rubber with low hardness countersinks. Suitable for home DIY and general construction/engineering use.
-
Safety and Stability - Caters to most pistols on the market to prevent slipping and falling off during rotation to increase safety in use.
