HSS Step Drill Bit performs smooth drilling in several diameters with one drill bit
The step drill bit is made of HSS (high-speed steel) and offers a long lifetime when using coolant. Easily visible and durable markings of the hole diameter are provided by laser-marked figures in both spiral flutes. In addition, the 3-flat shank prevents slipping in the chuck and also provides powerful high-torque transmission.
