Guhring 9024640057900 Jobber Drill Bit 0.228in Carbide

Product Description

The GUHRING 9024640057900 is a jobber-length twist drill bit designed for precision drilling in non-ferrous and light-alloy materials. Built from solid carbide grade K40 and finished with a FIREX coating, this bit delivers extended tool life and consistent hole quality in demanding production environments. It carries a 118-degree faceted point angle with web thinning for improved centering and reduced thrust. The straight-cylindrical shank measures 5.79 mm in diameter, making it compatible with standard drill chucks. At 0.2280 inches in diameter, this is a wire gauge size 1 drill bit suited for machinists, toolroom technicians, and production floor operators.

This drill bit is built for use in CNC machining centers, drill presses, and hand-held power tools where precise hole sizing in aluminum and other non-ferrous materials is required. The FIREX coating improves surface hardness and heat resistance, extending service intervals in high-cycle applications. The Series 2464 design follows DIN specification standards, making it a recognized format for shops running metric tooling programs. It is well suited for general-purpose production drilling where repeatable diameter tolerance and controlled chip evacuation are priorities.

Key Features

• Solid carbide K40 grade construction for wear resistance in non-ferrous materials
• FIREX coating improves heat resistance and extends tool life in high-cycle use
• 118-degree faceted point with web thinning for accurate self-starting entry
• Right-hand spiral flute with regular helix promotes efficient chip evacuation
• Straight-cylindrical shank fits standard drill chucks without adapters
• DIN specification Series 2464 format for consistent dimensional compliance

Compatibility

Designed as a general-purpose jobber-length carbide drill bit per DIN specification, Series 2464, suitable for use in standard drill chucks and collet holders accepting a 5.79 mm straight-cylindrical shank. Primary workpiece material designation is N, corresponding to aluminum and non-ferrous alloys.

Installation Notes

Installation and tool changes should be performed by a qualified machinist with the spindle fully stopped and the machine locked out. Secure the shank fully within the chuck or collet to the recommended grip depth before tightening. Carbide tooling is brittle and should not be subjected to side loads or interrupted cuts beyond the tool's rated application. Inspect the cutting edges and coating condition before each use and replace the bit if chipping or wear is evident.
