Guhring 9024630049200 Carbide Stub Drill Bit Wire 10

Product Description

The GUHRING 9024630049200 is a solid carbide stub-length (screw machine length) drill bit designed for precision drilling in aluminum and other non-ferrous materials. Carrying a wire gauge designation of No. 10 (0.1935 inches), it features a 118-degree faceted point angle and a FIREX coating for improved surface hardness and heat resistance. The two-flute, right-hand spiral design handles chip evacuation efficiently in short-hole applications. At 2.441 inches overall length with a 1.024-inch flute length, this stub-length geometry provides rigidity and reduced deflection. It is intended for installation in CNC machining centers, drill presses, or hand-held power tools used by machinists and tool-and-die professionals.

This drill bit is suited for production and job-shop environments where short-hole drilling in aluminum is the primary application. The stub-length body minimizes overhang, making it a practical choice for tight-tolerance work on fixtures, molds, and component parts. The straight-cylindrical shank (0.1937-inch diameter) seats securely in standard drill chucks and collets. It conforms to DIN 6539 standards and is built to the Series 2463 specification, making it a traceable, specification-grade tooling option for shops that document tooling compliance.

Key Features

• Solid carbide construction in material grade K40 for hardness and wear resistance in non-ferrous cutting
• FIREX coating enhances surface hardness and reduces built-up edge on aluminum
• 118-degree faceted point with web thinning for reduced thrust force on entry
• Stub-length (screw machine length) body at 2.441 inches overall for maximum rigidity
• Right-hand, two-flute regular spiral for efficient chip removal in through and blind holes
• Conforms to DIN 6539; built to Series 2463 specification

Compatibility

Designed as a general-purpose stub-length drill bit for use in standard drill chucks and collets accepting a straight-cylindrical shank of 0.1937 inches. Primary workpiece material designation is aluminum; suitable for other non-ferrous and soft materials within the general-purpose performance class.

Installation Notes

This tool should be installed by a qualified machinist or toolroom technician familiar with carbide tooling handling procedures. Carbide is brittle — avoid impact or side-loading during chuck installation. Confirm chuck or collet runout is within acceptable tolerance before drilling to protect the cutting edge. Inspect the point and flutes for chipping before each use; do not run a damaged carbide tool.
