Guhring 9024630102000 Stub Drill Bit 0.4016 in Solid Carbide

Product Description

The GUHRING 9024630102000 is a solid carbide stub-length (screw machine length) drill bit designed for precision drilling in aluminum and other non-ferrous materials. It measures 0.4016 inches (10.20 mm) in diameter with a 118-degree faceted drill point and a web-thinned tip that reduces entry force and improves centering. The overall length is 3.504 inches (89.00 mm), and the spiral flute length is 1.693 inches (43.00 mm). Built to DIN 6539 standards from K40 carbide grade, this bit delivers consistent dimensional accuracy with a diameter tolerance of +0.000 to -0.010 mm. It is installed by machining professionals and toolroom technicians requiring reliable, repeatable hole quality.

This drill bit is suited for screw machine operations, CNC machining centers, and manual drilling setups where a short, rigid tool is preferred to minimize deflection. Its primary workpiece material rating is aluminum, making it well-matched for production environments that process aluminum components at moderate to high cycle rates. The straight-cylindrical shank accommodates standard drill chucks and collet holders. With a flute-to-diameter ratio of 3xD and a maximum drilling depth of 1.091 inches (27.70 mm), it is optimized for stub-depth holes where rigidity and chip evacuation are priorities.

Key Features

• Solid carbide K40 grade construction for wear resistance in aluminum applications
• 118-degree faceted drill point with web thinning for reduced thrust and improved self-centering
• Regular spiral, 2-flute design for efficient chip evacuation in non-ferrous materials
• Stub length (screw machine length) for increased rigidity and reduced deflection
• Diameter tolerance of +0.000 to -0.010 mm for close-tolerance hole production
• Conforms to DIN 6539 specification for consistent geometry and interchangeability

Compatibility

Designed as an OEM-style replacement or direct-use tooling for setups requiring a DIN 6539 stub-length carbide drill bit with a 10.20 mm straight-cylindrical shank, compatible with standard drill chucks and collet systems accepting that shank diameter. No specific machine model compatibility was provided by the manufacturer for this listing.

Installation Notes

This bit is installed by machinists and toolroom technicians in CNC or manual drilling equipment. Ensure the spindle and chuck are clean and free of runout before seating the shank, as carbide tooling is sensitive to lateral loading. Secure the straight-cylindrical shank firmly in the collet or chuck to the full clamping depth before operation. Carbide drill bits should not be used in hand-held drills or applications with excessive vibration, as carbide is brittle and will fracture under impact or flex loading.
