Deburring zone / edge breakerWith deburring zones on the drill step 10 mm. For deburring the drill holes at the back. From professionals for professionals. |
Quick release shaftWith E 6.3 mm quick release shaft for direct absorption of hand-held machines. We recommend use on high-torque stand drills. Please read our application recommendations below. |
Spiral groove / TiaLn coatingSpiral groove for optimal chip removal, especially with non-breaking chips such as stainless steel. The groove is titanium aluminium nitride coated and also supports chip removal. From professionals for professionals. |
Transition reinforcementWhen using step drills, relatively high torque is created at low RPM. Therefore, we generally recommend the use on stand drills. Our quick-release models are equipped with a transition reinforcement at the transition from shaft to base body to prevent breakage. From professionals for professionals. |
