Guhring 9024630088400 Stub Drill Bit 0.348in Solid Carbide

Product Description

The GUHRING 9024630088400 is a stub-length (screw machine length) solid carbide drill bit designed for precision hole-making in aluminum and similar non-ferrous materials. Built to DIN 6539 standards and designated as Series 2463, it features a 118-degree faceted point angle with web thinning for improved centering and reduced thrust at entry. The 2-flute spiral configuration with a regular helix promotes efficient chip evacuation in short-depth applications. The straight-cylindrical shank measures 8.84 mm and seats reliably in standard drill chucks or collet systems used by machinists and maintenance mechanics across production and job-shop environments.

This bit is suited for stub-length drilling operations where rigidity is prioritized over reach. The shortened flute length and overall compact body reduce deflection in tight setups or fixtures. Primary workpiece material is aluminum, though the coated solid carbide construction handles general-purpose applications across K40-grade material groups. A maximum drilling depth of 1.053 inches keeps it appropriate for through-holes and shallow blind holes in production machining, toolroom, and maintenance contexts. The 3xD flute-to-diameter ratio supports controlled chip flow without packing.

Key Features

• Solid carbide construction, K40 material grade, for hardness and wear resistance
• 118-degree faceted point angle with web thinning for accurate entry and reduced thrust
• 2-flute spiral configuration promotes chip evacuation in aluminum and non-ferrous materials
• Stub (screw machine) length body maximizes rigidity and minimizes deflection
• Coated finish extends cutting edge life in general-purpose applications
• Conforms to DIN 6539 specification for dimensional consistency

Compatibility

Designed as an OEM-style replacement or direct-use stub drill for general-purpose machining operations targeting aluminum and similar materials, conforming to DIN 6539 dimensional standards.

Installation Notes

Installation is performed by machinists or maintenance technicians using standard drill press, CNC machining center, or lathe tailstock setups. Secure the straight-cylindrical shank in a properly sized collet or drill chuck before operation. Confirm spindle speed and feed rate are appropriate for the workpiece material and bit diameter before engaging the cut. Solid carbide tooling is brittle compared to high-speed steel — avoid side loading, interrupted cuts without proper setup, or using the bit to ream or enlarge existing holes beyond its rated tolerance.
