RUKO HSS stepped drill bit Ø 6.0-37.0 mm (12 steps) for precise drilling.

The Ruko-101060 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 precise drilling starts. With a 118° cutting angle and a 90° taper angle, this drill bit ensures efficient and clean cutting, minimizing the risk of burrs and vibrations during use.

CBN (Cubic Boron Nitride) grinding and spiral chip flutes optimize the drilling process, guaranteeing superior performance and quiet operation. Each step of the drill bit is radially adjusted and ground, and the steps are laser-marked for easy identification.
