The Ruko-101052 step drill bit is a high-precision tool designed for drilling sheet metal in various industries, including electrical, plumbing, heating, and automotive. Its innovative design incorporates a split point cutting edge according to DIN 1412 C, allowing for easier and more effective drilling starts. With a 118° cutting angle and a 90° taper angle, this drill bit ensures efficient and clean cutting.
The CBN (Cubic Boron Nitride) grinding and spiral chip flutes optimize the drilling process, minimizing noise, vibration, and burr formation. Each step of the drill bit is radially adjusted and ground, guaranteeing exceptional accuracy with every use.
The steps are laser-marked for easy identification and selection of the correct diameter.This tool is suitable for sheet metal up to 4 mm thick and comes in a translucent plastic case with a hanger for easy storage and transport.
