Guhring 9024630107200 Screw Machine Drill 27/64 Carbide

Product Description

The GUHRING 9024630107200 is a stub-length, solid carbide screw machine drill bit engineered for precision drilling in demanding shop and field applications. Sized at 27/64 inch (0.4219 inches) in diameter, it features a 118-degree faceted point angle and a web-thinned tip geometry that reduces entry thrust and improves centering accuracy. The two-flute, regular spiral design promotes efficient chip evacuation, and the straight-cylindrical shank provides a secure, concentric grip in standard drill chucks or collet holders. This bit is built to DIN 6539 standards and carries a K40 carbide grade designation, making it appropriate for general-purpose work with a primary focus on aluminum and similar non-ferrous workpiece materials.

The 9024630107200 is suited for production and maintenance environments where compact stub-length tooling is preferred for rigidity and reduced deflection in short-reach applications. Its 1.85-inch flute length and 3.74-inch overall length fit standard CNC machining centers, drill presses, and hand-held pneumatic tools. The maximum drilling depth is 1.217 inches, consistent with the 3xD flute-to-diameter ratio. Licensed machinists, tool-and-die technicians, and industrial maintenance mechanics are the primary installers and users of this tooling.

Key Features

• Solid carbide K40 grade construction for wear resistance and dimensional consistency
• 118-degree faceted point angle with web thinning for reduced entry thrust
• Stub (screw machine) length at 3.74 inches overall for improved rigidity and reduced deflection
• Two-spiral flutes with regular helix for reliable chip evacuation
• DIN 6539 compliant with a diameter tolerance of +0.000 to -0.010 mm
• Right-hand cut, straight-cylindrical shank compatible with standard chucks and collets

Compatibility

Designed as a general-purpose stub-length carbide drill bit per DIN 6539, Series 2463, suitable for use in CNC machining centers, drill presses, and pneumatic drilling equipment that accept a straight-cylindrical shank. Primary workpiece material compatibility is aluminum; the tool is classified for general-purpose use across non-ferrous and similar materials within the 0.4000 to 0.4500 inch drill bit size range.

Installation Notes

This drill bit should be installed by qualified machinists or maintenance technicians familiar with cutting tool selection and machine setup. Ensure the spindle and chuck or collet are de-energized and fully stopped before inserting or removing the bit. Verify chuck or collet runout is within acceptable limits before use, as excessive runout accelerates carbide edge wear. Coolant-through is not supported on this tool; external coolant or cutting fluid application is recommended when drilling at depth.
