Guhring 9024640059000 Jobber Drill Bit 5.9mm Carbide

Product Description

The GUHRING 9024640059000 is a jobber-length drill bit engineered for precision drilling in non-ferrous and light alloy materials. Built from solid carbide grade K40, this bit carries a FIREX coating that extends tool life and reduces built-up edge when cutting aluminum and similar workpiece materials. The 118-degree faceted point geometry with web thinning promotes clean entry and self-centering without a pilot hole. At 3.66 inches overall length with a 2.24-inch flute length, the bit fits standard jobber-length applications on CNC machining centers, drill presses, and handheld power tools. It weighs 0.05 pounds and ships as a single unit.

This drill bit is sized at 5.9 mm (0.2323 inches) diameter with a matching 5.9 mm straight-cylindrical shank, making it compatible with standard collets, keyless chucks, and drill-press spindles that accept that shank diameter. It is part of the GUHRING Series 2464 and follows DIN specification guidelines. Primary application is drilling aluminum and other non-ferrous metals in production and maintenance environments. The regular spiral flute design and 5xD flute-to-diameter ratio support chip evacuation in general-purpose drilling cycles. Licensed machinists, tool-and-die technicians, and maintenance mechanics are the typical users.

Key Features

• Solid carbide K40 grade construction for rigidity and wear resistance in non-ferrous materials
• FIREX coating reduces friction and extends cutting edge life
• 118-degree faceted point with web thinning for accurate self-centering entry
• Right-hand spiral flute promotes efficient chip evacuation
• Straight-cylindrical shank fits standard collets and keyless chucks
• DIN-specification geometry ensures dimensional consistency across replacement bits

Compatibility

Designed as a general-purpose jobber-length drill bit suitable for use in CNC machining centers, drill presses, and power tools equipped with collets or chucks that accept a 5.9 mm straight-cylindrical shank. Primary workpiece material designation is N (non-ferrous, aluminum alloys).

Installation Notes

Installation is performed by machinists or maintenance technicians. Secure the shank fully in the collet or chuck before operation and verify runout with a dial indicator on precision setups. Do not exceed the maximum drilling depth of 1.896 inches (48.15 mm) per the Series 2464 design envelope. Cutting speeds and feed rates should follow the manufacturer published charts for carbide tooling in the specific workpiece material; applying excessive force can cause carbide fracture.
