Guhring 9024630028000 Stub Drill Bit 2.80mm Solid Carbide

Product Description

The GUHRING 9024630028000 is a stub-length (screw machine length) solid carbide drill bit designed for precision drilling in light-metal and general-purpose machining applications. Built to DIN 6539 standards, it measures 2.80 mm (0.1102 inches) in diameter with an overall length of 46.00 mm (1.8110 inches) and a flute length of 16.00 mm (0.6300 inches). The 118-degree faceted drill point and web-thinned geometry reduce thrust and improve centering accuracy. This bit is suited for machinists and toolroom professionals who require consistent, repeatable performance in production environments.

This drill bit is intended for drilling aluminum and other non-ferrous or light materials in production machining, CNC, and manual drill press setups. The stub-length body provides added rigidity compared to jobber-length bits, making it well-suited for short-hole drilling where deflection control is critical. With a maximum drilling depth of 0.4650 inches (11.80 mm) and a 3xD flute-to-diameter ratio, it handles typical through-hole and shallow blind-hole work efficiently. It is sold individually and carries a minimum order quantity of one piece.

Key Features

• Solid carbide construction for wear resistance and dimensional consistency in high-cycle production drilling
• 118-degree faceted drill point with web-thinning for reduced entry thrust and improved self-centering
• Stub (screw machine) length body delivers increased rigidity and reduced deflection versus standard jobber-length bits
• 2-flute spiral design with regular spiral type optimized for chip evacuation in aluminum and similar materials
• Straight-cylindrical shank compatible with standard drill chucks and collet holders
• Manufactured to DIN 6539 specification with K40 carbide grade for consistent tolerance control

Compatibility

Designed as an OEM-style replacement or direct-fit tooling option for CNC machining centers, drill presses, and manual lathes accepting a 2.80 mm straight-cylindrical shank drill bit. Primary workpiece material is aluminum; general-purpose use in non-ferrous and light ferrous materials is also supported.

Installation Notes

Installation and tool-setting should be performed by a qualified machinist or toolroom technician following standard toolholding procedures. Ensure the machine spindle is fully stopped and locked out before inserting or removing the bit from the chuck or collet. Verify shank seating depth and runout before beginning a drilling cycle. Consult the machine manufacturer's recommended speeds and feeds for 2.80 mm solid carbide tooling in the target workpiece material.
