Guhring 9024640058000 Jobber Drill Bit 5.8mm Carbide

Product Description

The GUHRING 9024640058000 is a jobber-length drill bit engineered for precision drilling in non-ferrous and aluminum workpieces. Built from solid carbide grade K40, it carries a FIREX coating that extends tool life under demanding cutting conditions. The bit features a 118-degree faceted point, a web-thinned tip for reduced thrust at entry, and a two-flute regular spiral geometry that promotes efficient chip evacuation. Overall length is 3.66 inches (93 mm), with a flute length of 2.24 inches (57 mm) and a maximum drilling depth of 1.90 inches (48.3 mm). It is sized at 5.8 mm (0.2283 inches) in both cutting diameter and straight-cylindrical shank diameter. Licensed machinists, tooling technicians, and production floor operators are the primary users of this tool.

This drill bit belongs to the Guhring Series 2464 and is suited for general-purpose hole-making operations in aluminum and other non-ferrous materials (Material Grade N). The 5xD flute-to-diameter ratio makes it appropriate for standard-depth through-holes and blind bores in machining centers, CNC lathes, and drill presses. Its straight-cylindrical shank fits standard ER collets and drill chucks without adapters. The DIN specification designation confirms dimensional conformance to European standard tooling requirements, supporting interchangeability in production environments.

Key Features

• Solid carbide K40 substrate delivers rigidity and wear resistance in abrasive non-ferrous materials
• FIREX coating reduces friction and extends tool life at higher cutting speeds
• 118-degree faceted point with web thinning lowers entry thrust and improves centering accuracy
• Two-flute regular spiral geometry supports effective chip clearance in aluminum
• 5xD flute-to-diameter ratio accommodates standard-depth drilling applications
• Diameter tolerance of -0.012 to 0.000 mm ensures consistent, on-size hole production

Compatibility

Designed as a general-purpose jobber-length drill bit for use in standard ER collet chucks and keyed or keyless drill chucks that accept a 5.8 mm straight-cylindrical shank. Intended for drilling aluminum and non-ferrous materials per primary workpiece material code N.

Installation Notes

Secure the shank fully in the collet or chuck before operation and verify runout with a dial indicator when hole tolerance is critical. Power down and lock out the machine spindle before changing or inspecting tooling. Do not exceed the maximum drilling depth of 48.3 mm in a single pass without retracting to clear chips. Coolant-through is not supported on this tool; apply flood or mist coolant externally as needed per shop practice.
