Guhring 9024640055000 Solid Carbide Jobber Drill Bit 5.5mm

Product Description

The GUHRING 9024640055000 is a solid carbide jobber-length drill bit designed for precision drilling in aluminum and other non-ferrous materials. It features a FIREX coating that reduces friction and extends tool life in production environments. The bit measures 5.5 mm in diameter with an overall length of 3.66 inches (93 mm) and a 118-degree faceted point angle. Web thinning reduces thrust force at the cutting tip, improving entry accuracy and chip evacuation. This bit is intended for use by machinists and tool-and-die professionals working with CNC machining centers, drill presses, and hand-feed drilling operations.

This drill bit is suited for general-purpose drilling in aluminum and similar non-ferrous workpiece materials. The straight-cylindrical shank fits standard drill chucks across a wide range of machine tool setups. With a flute-to-diameter ratio of 5xD and a spiral flute design, it handles moderate-depth holes up to 1.919 inches (48.75 mm) in a single pass without peck drilling in most aluminum applications. It is part of the Guhring Series 2464 line, manufactured to DIN specification standards.

Key Features

• FIREX coating reduces friction and extends tool life in non-ferrous drilling
• 118-degree faceted point with web thinning for reduced entry thrust and improved chip flow
• Solid carbide construction (Material Grade K40) for rigidity and wear resistance
• 5xD flute-to-diameter ratio supports drilling up to 48.75 mm deep
• Right-hand spiral flute with regular helix for consistent chip evacuation
• Straight-cylindrical shank fits standard drill chucks without an adapter

Compatibility

Designed for use in CNC machining centers and drill presses accepting a 5.5 mm straight-cylindrical shank. Primary workpiece material is aluminum (material code N). Fits drill chucks within the 5.00 mm to 6.00 mm diameter range per Series 2464 DIN specifications.

Installation Notes

Installation and use should be performed by qualified machinists familiar with carbide tooling. Ensure the drill chuck is clean and free of debris before seating the shank to maintain runout tolerances within the stated diameter tolerance of -0.012 to 0.000 mm. Solid carbide bits are brittle compared to HSS; avoid side loading and interrupted cuts without verifying setup rigidity. Coolant-through is not supported on this bit, so apply external flood or mist coolant appropriate to the workpiece material.
