Guhring 9024640107200 Carbide Jobber Drill Bit 27/64 in

Product Description

The GUHRING 9024640107200 is a solid carbide jobber-length drill bit designed for precision drilling in demanding shop and field applications. Built to DIN specification under GUHRING Series 2464, it features a 118-degree faceted point and a FIREX coating that extends tool life in abrasive and high-temperature cutting conditions. The 27/64 inch (0.4219 inches decimal) diameter bit runs a right-hand spiral flute with web-thinned geometry, reducing thrust and improving chip evacuation. At a 5xD flute-to-diameter ratio, it delivers consistent hole quality in production environments. Machinists, tool-and-die tradespeople, and maintenance professionals working in metalworking and fabrication shops are the primary users of this bit.

This drill bit is rated for general-purpose drilling with a primary workpiece material designation of N, indicating suitability for non-ferrous metals including aluminum. The straight-cylindrical shank with a 10.72 mm diameter seats securely in standard drill chucks and collet holders. With an overall length of 5.59 inches (142 mm) and a flute length of 3.70 inches (94 mm), it handles a maximum drilling depth of 3.068 inches (77.92 mm), making it appropriate for through-hole and blind-hole work in typical machining setups.

Key Features

• Solid carbide construction, Material Grade K40, for rigidity and wear resistance in non-ferrous and general-purpose drilling
• FIREX coating reduces friction and extends tool life in high-speed cutting conditions
• 118-degree faceted point with web-thinned geometry lowers entry thrust and improves centering accuracy
• Right-hand spiral flute with regular spiral type ensures efficient chip evacuation
• Straight-cylindrical shank compatible with standard drill chucks and collet systems
• Built to DIN specification, Series 2464, for consistent dimensional tolerances

Compatibility

Designed as a general-purpose jobber-length drill bit suitable for use in CNC machining centers, manual drill presses, and hand-held drilling equipment accepting a straight-cylindrical shank. Primary workpiece material designation N indicates optimized performance in aluminum and other non-ferrous materials.

Installation Notes

Installation and use of this bit should be performed by qualified machinists or maintenance tradespeople familiar with cutting tool safety practices. Ensure the machine spindle is fully stopped and locked out before installing or changing the bit. Seat the straight-cylindrical shank fully and evenly in the chuck or collet and verify runout before beginning a cut. Do not exceed the recommended maximum drilling depth of 3.068 inches without retracting to clear chips.
