Guhring 9024630800 Solid Carbide Drill Bit 0.397 in

Product Description

The GUHRING 9024630800 is a stub-length (screw machine length) solid carbide twist drill designed for precision hole-making in production and maintenance environments. Built to DIN 6539 standards and manufactured from K40 carbide grade, this drill features a 118-degree faceted point angle with web thinning for reduced thrust and cleaner entry. At 0.397 inches (10 mm nominal) in diameter with a straight-cylindrical shank, it is sized for use in standard drill chucks and collet holders. The two-flute spiral design provides efficient chip evacuation, and the coated finish extends cutting-edge life in demanding applications. Installers and machinists working in high-cycle environments will find this drill well-suited to tight-tolerance work.

This drill is rated for general-purpose use with a primary workpiece material designation of aluminum, though its solid carbide construction and coated finish make it capable across a range of non-ferrous and ferrous materials at appropriate feeds and speeds. The stub-length (3xD flute-to-diameter ratio) body keeps deflection low, making it a common choice for CNC machining centers, drill presses, and screw machine setups where rigidity and repeatability matter. It carries a DIN 6539 specification designation and falls within the 0.350 to 0.400 inch drill diameter range of the Series 2463 product family.

Key Features

• Solid carbide K40 grade construction for rigidity and wear resistance
• 118-degree faceted drill point with web thinning for reduced entry thrust
• Stub (screw machine) length body limits deflection in short-reach applications
• Right-hand cut, two-flute spiral design promotes efficient chip evacuation
• Coated finish extends tool life across repeated cutting cycles
• DIN 6539 compliant; diameter tolerance held to +0.000 to -0.010 mm

Compatibility

Designed as a general-purpose stub-length drill for use in CNC machining centers, drill presses, and screw machines accepting a straight-cylindrical shank. Compatible with standard drill chucks and collet systems sized for a 10.08 mm (0.397 inch) shank diameter. Fits within the GUHRING Series 2463 drill family covering the 0.350 to 0.400 inch diameter range.

Installation Notes

Installation and operation should be performed by a qualified machinist or toolroom technician familiar with carbide tooling requirements. Ensure the spindle and workholding are fully secured before initiating a cut. Carbide drills are brittle compared to high-speed steel — avoid side loading, interrupted cuts without appropriate feeds and speeds, or excessive runout in the holder, as these conditions can cause chipping or breakage. Do not use coolant-through settings on this drill as it is not rated for through-coolant.
