The Ruko-101058 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 efficient drilling starts. With a 118° cutting angle and a 90° taper angle, this drill bit ensures a clean, precise cut, optimizing performance with every use.
CBN (Cubic Boron Nitride) grinding and spiral chip flutes are features that guarantee a clean and precise cut, minimizing noise, vibration, and burr formation. Each step of the drill bit is radially adjusted and ground, providing greater durability and work efficiency.
Furthermore, the steps are laser-marked for easy identification and use.- Diameter: Ø 5.0-28.0 mm (7 steps)
