The GUHRING 9003360025800 is a cobalt taper length drill bit designed for high-performance drilling in demanding materials. It carries a 130-degree drill point angle and a parabolic flute geometry that promotes efficient chip evacuation during deep-hole operations. The bright/uncoated finish suits applications where coating is unnecessary or undesirable. With a cylindrical shank measuring 0.1016 inches in diameter and a flute-to-diameter ratio of 10xD, this bit delivers controlled penetration in production and maintenance drilling environments. It is suited for licensed machinists, tool-and-die shops, and maintenance professionals working with hard metals.
This drill bit is rated for use in cast iron, hardened materials, stainless steel, and steel. The parabolic flute design supports deeper cuts relative to standard jobber-length bits, making it a practical choice when added reach is required without stepping up to an extended-length tool. Right-hand cutting direction is standard. The web-thinned, parallel web construction reduces entry force and improves centering at the point. It conforms to DIN 340 specification, which governs taper length drills in the metric and inch-equivalent market.
Designed as a DIN 340 taper length drill bit compatible with standard cylindrical-shank drill chucks used in drill presses, CNC machining centers, and hand-held drilling equipment. Rated material applications include cast iron, hardened materials, stainless steel, and steel as stated by the manufacturer.
Installation is performed by machinists or maintenance technicians using standard drill chuck equipment. Secure the cylindrical shank fully within the chuck jaws before operation and verify chuck runout is within acceptable limits for precision work. Coolant-through is not supported on this bit, so external coolant or cutting fluid should be applied at the cutting zone when drilling stainless steel or hardened materials to manage heat buildup. Follow applicable shop safety practices and machine guarding requirements during use.
