This HSS step drill bit is meticulously crafted to deliver clean, perfectly round holes with minimal effort. The advanced design ensures flawless results, saving you valuable time and eliminating the need for constant tool changes. Whether you´re creating pilot holes or enlarging existing ones up to a final diameter of 12 mm, this tool provides the accuracy and reliability required for professional-grade work. Its robust construction from high-speed steel guarantees exceptional durability and a long service life, even under demanding use in various metal applications.The core advantage of this step drill lies in its sophisticated geometry. The CBN ground and spiral flutes guarantee quiet running and high cutting performance. Especially the chip flow is optimized, so even long, non-breaking chips will be removed easily. This optimized chip flow protects the cutting edges and reduces built-up edges and cold weld marks. The cone makes it easier to withdraw the tool from the material, preventing snags and ensuring a smooth workflow from start to finish.Furthermore, the Shape C split point with a 118° angle allows for immediate, precise centering without the need for a center punch or pre-drilling. The bit engages the material instantly and prevents walking, ensuring your hole is exactly where you intend it to be. The secure, 3-way clamping surface on the shank prevents any slipping in the drill chuck, translating all of your power tool´s torque directly to the cutting edge for maximum efficiency. Each of the 9 steps is clearly marked, allowing for accurate drilling to the desired diameter every time. Elevate your toolkit with this single, powerful solution for multi-size hole drilling.Technical Specifications:* Ø: 4.0 - 12.0 mm* Total length: L1 65.0 mm* Shank: Ø 6.0 mm* Size no: 0/9* Steps: 9* Material: HSS* Surface: bright* Cutting direction: right hand cut* Shank 3-way clamping: surface* Point angle: 118°* Point cut: Shape C - Split point* Step angle: 90°* Weight: 0.02200 Kg. tradeinn Bricoinn
