The step drill bit head is made of HSS (high-speed steel) and coated with AlTiN (aluminum titanium nitride). This provides the longest possible lifespan and does not require the use of coolant. Laser-marked numbers in both spiral flutes provide highly visible and durable marking of the hole diameter. In addition the 3-flat shank prevents slipping in the drill chuck and provides efficient transmission with high torque. The HSS step drill bit head delivers smooth burr-free drilling in multiple diameters with a single drill bit. It is ideal for deburring drilling round holes and enlarging existing ones. It is not necessary to mark center points because the two-part tip provides easy starting. Its CNC-ground spiral flute allows for optimized chip removal and less vibration for smooth drilling. The most optimal cutting and absolute smoothness are ensured thanks to axial and radial clearance grinding. This step drill bit is suitable for use on thin materials such as non-ferrous metals sheet plastic sheet steel plastic and stainless steel. 9 steps Ø 4-5-6-7-8-9-10-11-12 mm
