Guhring 9024630053000 Carbide Stub Drill Bit 5.30mm

Product Description

The GUHRING 9024630053000 is a stub-length (screw machine length) solid carbide drill bit designed for precision hole-making in high-speed machining environments. Built to DIN 6539 standards and classified as Series 2463, this bit features a 118-degree faceted point, a web-thinned tip for reduced thrust and cleaner entry, and a right-hand spiral flute geometry optimized for chip evacuation. At 5.30mm (0.2087 inches) in diameter, it is sized for close-tolerance work with a diameter tolerance of +0.000 to -0.010mm. Licensed machinists and CNC operators working in production or job-shop settings will find this tool suited for general-purpose drilling in aluminum and similar non-ferrous materials.

This drill bit is intended for use in screw machine and CNC drilling operations where stub-length rigidity is required to minimize deflection and improve hole straightness. With a 3xD flute-to-diameter ratio and a maximum drilling depth of 0.711 inches (18.05mm), it is best applied in shallow-to-moderate-depth hole applications. The straight-cylindrical shank fits standard chucks and collets without modification, making it compatible with bench drill presses, machining centers, and automated screw machines. It is particularly well-suited for aluminum workpieces where consistent diameter and surface finish matter.

Key Features

• Solid carbide construction for extended tool life in abrasive and high-speed applications
• 118-degree faceted drill point with web thinning for reduced entry thrust and improved centering
• Two-flute regular spiral design promotes efficient chip evacuation
• Stub-length body increases rigidity and reduces deflection in short-depth drilling
• DIN 6539 standard and K40 carbide grade ensure consistent dimensional and performance compliance
• Straight-cylindrical shank fits standard collets and chucks without adapters

Compatibility

Designed as an OEM-style general-purpose stub drill for use in CNC machining centers, screw machines, and drill presses where a 5.30mm straight-shank carbide drill is specified. Primary workpiece material is aluminum; suitable for other non-ferrous materials within the general-purpose performance tier.

Installation Notes

Installation and tool changes must be performed with the machine fully powered down and the spindle at a complete stop. Secure the straight-cylindrical shank firmly in a collet or drill chuck rated for the intended RPM before operation. Follow the machine tool manufacturer guidelines and applicable ANSI or shop safety standards for carbide tooling setup and runout verification. Do not use this bit beyond its rated maximum drilling depth of 0.711 inches without retracting to clear chips.
