Guhring 9024640046000 Carbide Jobber Drill Bit 4.6mm

Product Description

The GUHRING 9024640046000 is a solid carbide jobber length drill bit designed for precision drilling in aluminum and other non-ferrous materials. Built to DIN specifications under Series 2464, it features a 118-degree faceted point angle with web thinning for improved chip evacuation and reduced thrust at entry. The FIREX coating extends tool life in demanding applications. At 4.6 mm in diameter with a 3.15-inch overall length and a 1.85-inch spiral flute, this bit delivers a 5xD flute-to-diameter ratio suited for consistent, repeatable hole quality. It is typically installed by machinists and tool-and-die professionals in CNC and manual drilling operations.

This drill bit is suited for general-purpose drilling in aluminum and similar non-ferrous workpiece materials, corresponding to material code N. The straight-cylindrical shank accepts standard drill chucks and collet systems without modification. A maximum drilling depth of 1.579 inches makes it appropriate for through-holes and moderate-depth blind holes in production and job shop environments. The right-hand spiral flute geometry promotes efficient chip removal during standard rotational drilling. It ships individually and is ordered in single-unit quantities.

Key Features

• Solid carbide construction at material grade K40 for rigidity and wear resistance
• FIREX coating for extended tool life in aluminum and non-ferrous applications
• 118-degree faceted point with web thinning to reduce thrust and improve centering
• Right-hand cut, regular spiral flute for efficient chip evacuation
• Straight-cylindrical shank compatible with standard drill chucks and collets
• Built to DIN specification for dimensional consistency

Compatibility

Designed as a general-purpose jobber length drill bit for use in standard drill chucks and collet holders accepting a 4.6 mm straight-cylindrical shank, suitable for CNC machining centers and manual drill presses.

Installation Notes

Installation and use of this drill bit should be performed by qualified machinists familiar with carbide tooling. Ensure the drill chuck or collet is fully secured and the machine spindle is powered down before tooling changes. Carbide bits are brittle compared to high-speed steel; avoid side loading or impact that can cause chipping. Verify spindle speed and feed rate are appropriate for the workpiece material and bit diameter before operation.
