RUKO HSS Stepped Drill Bit Ø 4.8-10.65 mm (5 steps) for precise drilling.

The Ruko-101094 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 burr generation and vibration during use.

The CBN (Cubic Boron Nitride) grinding and spiral chip flutes optimize the drilling process, guaranteeing superior performance and a professional finish. Each step of the drill bit is radially adjusted and ground, with clearly laser-marked steps for ease of use.
