HSS Twist Drill Bit

The SPS series HSS twist drills are designed for precise and efficient drilling in metalworking applications using magnetic drilling machines. Equipped with a 19 mm (3/4") Weldon shank, these drills ensure secure and stable clamping in magnetic drill tool holders. Manufactured from high-speed steel (HSS), the drills offer reliable cutting performance, durability, and resistance to wear. The 35 mm flute length allows efficient chip removal and smooth drilling operation, even in demanding conditions. These twist drills are ideal for drilling solid materials such as structural steel, mild steel, and general metal applications. Compared to annular cutters, they are especially suitable for smaller diameters and through-hole drilling where full material removal is required. The SPS series is available in multiple diameters, providing flexibility for various drilling requirements. Their compatibility with standard Weldon tool holders makes them a versatile solution for professional users in workshops, fabrication, and construction environments.
