Guhring 9024640024900 Carbide Drill Bit No. 40 Firex

Product Description

The GUHRING 9024640024900 is a solid carbide jobber-length drill bit in wire gauge size No. 40, with a decimal diameter of 0.0980 inches. It carries a FIREX coating and features a 118-degree faceted point with web thinning for reduced thrust on entry. The overall length is 2.24 inches (57 mm) with a flute length of 1.18 inches (30 mm). Intended for use by machinists and tool-and-die professionals, this bit is part of the Guhring Series 2464 product line. The straight-cylindrical shank and right-hand spiral flute geometry make it compatible with standard drill chucks and CNC drilling setups.

This drill bit is engineered for general-purpose drilling with a primary application in aluminum and other non-ferrous materials, as indicated by the N workpiece material code. The 5xD flute-to-diameter ratio supports chip evacuation in moderate-depth holes. With a maximum drilling depth of 1.034 inches (26.27 mm) and a shank diameter of 2.49 mm, it suits precision work in light manufacturing, aerospace component fabrication, and tool rooms where tight diameter tolerances are required. The FIREX coating provides thermal resistance and surface hardness suited to dry or near-dry cutting conditions in non-ferrous applications.

Key Features

• FIREX coating for increased surface hardness and thermal resistance in non-ferrous cutting
• 118-degree faceted point with web thinning reduces entry thrust and improves centering
• Solid carbide construction in material grade K40 for rigidity and wear resistance
• Right-hand cut, regular spiral flute for efficient chip evacuation
• Straight-cylindrical shank fits standard drill chucks and collets
• Manufactured to DIN specification with a diameter tolerance of -0.012 to 0.000 mm

Compatibility

Designed as an OEM-style general-purpose jobber drill bit suitable for use in standard drill chucks, CNC machining centers, and bench drill presses accepting straight-cylindrical shanks in the 0.0500 to 0.1000 inch diameter range.

Installation Notes

Installation and use should be performed by qualified machinists or tooling professionals. Secure the shank fully in a precision drill chuck or collet and verify runout before use. Power down all equipment and follow lockout/tagout procedures before changing tooling. Do not exceed the rated maximum drilling depth of 1.034 inches without retracting to clear chips.
