Guhring 9024640059400 Drill Bit Letter a Solid Carbide

Product Description

The GUHRING 9024640059400 is a jobber length drill bit in Letter A size (0.2340 inches), manufactured from solid carbide with a FIREX coating. It belongs to the Series 2464 line and is designed for general-purpose drilling in aluminum and other non-ferrous materials classified under material code N. The bit features a 118-degree faceted drill point, a web-thinned tip for reduced thrust and improved entry, and a regular spiral flute with right-hand cut. Overall length is 3.66 inches (93 mm), and the flute length is 2.24 inches (57 mm). Licensed HVAC, plumbing, electrical, and mechanical tradespeople rely on precision carbide tooling like this for clean, repeatable holes in light-metal components.

This drill bit is suited for use in CNC machining centers, drill presses, and hand-held drilling equipment where consistent hole tolerance is required. The straight-cylindrical shank diameter of 5.94 mm fits standard keyless and keyed chucks in that size range. With a maximum drilling depth of 1.893 inches (48.09 mm) and a 5xD flute-to-diameter ratio, it handles typical jobber-depth holes in sheet stock and billet aluminum. The FIREX coating provides elevated surface hardness and heat resistance, extending tool life in production or repetitive-use environments.

Key Features

• Letter A size, 0.2340-inch diameter with a tolerance of -0.012 to 0.000 mm for precise hole sizing
• Solid carbide construction, Material Grade K40, for rigidity and wear resistance
• FIREX coating for enhanced heat resistance and extended tool life
• 118-degree faceted point with web thinning for reduced entry force
• Right-hand cut, regular spiral flute with 2-flute geometry for efficient chip evacuation
• Straight-cylindrical shank for compatibility with standard drill chucks

Compatibility

Designed as a general-purpose jobber length drill bit optimized for aluminum and non-ferrous workpiece materials, conforming to DIN specification standards. Suitable for use in any drilling setup that accommodates a 5.94 mm straight-cylindrical shank.

Installation Notes

Installation and use should be performed by a qualified machinist or trade professional familiar with carbide tooling. Ensure the drill chuck is securely tightened and the workpiece is firmly clamped before operation. Solid carbide bits are brittle compared to high-speed steel and should not be used in flex-shaft or unstable setups where lateral loading may occur. Follow machine manufacturer speed and feed recommendations for carbide tooling in the applicable workpiece material.
