Guhring 9024640075000 Solid Carbide Jobber Drill Bit

Product Description

The GUHRING 9024640075000 is a solid carbide jobber-length drill bit designed for precision drilling in non-ferrous and light alloy materials. Manufactured to DIN specification in Series 2464, it features a 118-degree faceted point angle and a FIREX coating that improves wear resistance and reduces built-up edge when cutting aluminum and similar workpiece materials. The bit carries a material grade of K40 carbide and incorporates web thinning at the point to reduce thrust and improve centering. A regular spiral flute with a 5xD flute-to-diameter ratio promotes efficient chip evacuation. Licensed HVAC and mechanical technicians, machinists, and maintenance professionals routinely use bits in this class for production and repair drilling operations.

This bit is suited for general-purpose drilling in aluminum and other non-ferrous materials coded as N-group workpiece material. The straight-cylindrical shank seats directly in standard drill chucks and collet holders without adaptation. At 7.5 mm in diameter with a 69 mm flute length and a maximum drilling depth of 57.75 mm, it handles typical through-hole and blind-hole applications found in light fabrication, HVAC equipment assembly, and general maintenance drilling. Right-hand cut geometry is standard for conventional CNC and manual drill press setups.

Key Features

• Solid K40 carbide construction for rigidity and extended tool life in non-ferrous materials
• FIREX coating reduces friction and built-up edge during aluminum cutting
• 118-degree faceted point with web thinning for accurate centering and reduced thrust
• Regular right-hand spiral flute with 5xD ratio for consistent chip evacuation
• Straight-cylindrical shank fits standard drill chucks and collet systems without adaptation
• DIN specification Series 2464 for dimensional consistency and interchangeability

Compatibility

Designed as a general-purpose jobber-length drill bit compatible with standard drill chucks, ER collet holders, and hydraulic toolholders accepting a 7.5 mm straight-cylindrical shank. Primary workpiece material designation is N-group, covering aluminum and other non-ferrous alloys.

Installation Notes

Installation and use should be performed by qualified machinists or maintenance professionals familiar with rotating cutting tool safety. Ensure the spindle is fully stopped and the machine is locked out before loading or changing the bit. Secure the shank fully within the chuck or collet to the recommended grip length before operation. Coolant-through capability is not available on this bit, so external coolant or air blast should be used when drilling deep holes to manage chip evacuation and heat.
