Guhring 9055100083000 Carbide Drill Bit 0.3268 in

Product Description

The GUHRING 9055100083000 is a solid carbide screw machine length drill bit designed for high-performance drilling in demanding industrial and machining applications. Built to DIN 6537K specification, this bit measures 0.3268 inches (8.30 mm) in diameter with an overall length of 3.504 inches (89.00 mm) and a flute length of 1.850 inches (47.00 mm). The 140-degree split point with SU geometry and web-thinned, parallel web configuration reduces entry force and improves chip evacuation. FIREX coating provides thermal and wear resistance for extended tool life across difficult-to-machine materials. Coolant-through capability supports high-speed production drilling where heat management is critical.

This Series 5510 drill bit is suited for production machining environments where tight tolerances and consistent hole quality are required. It is rated for use in brass, cast iron, hardened materials, nickel alloys, stainless steel, carbon and alloy steel, and titanium alloys. The straight-cylindrical shank with a 10.00 mm shank diameter allows it to seat securely in standard drill chucks and collet holders. With a 3xD flute-to-diameter ratio and a maximum drilling depth of 1.732 inches (44.00 mm), it is optimized for stub-length, high-precision hole-making in CNC machining centers, drill presses, and screw machine setups.

Key Features

• Solid carbide construction with FIREX coating for wear and heat resistance in difficult alloys
• 140-degree SU point with web thinning for reduced thrust and accurate self-centering entry
• Coolant-through design supports high-speed drilling and chip flushing in deep-hole applications
• DIN 6537K specification with diameter tolerance of +0.006 to +0.021 mm for consistent hole sizing
• Straight-cylindrical shank compatible with standard collet chucks and drill holders
• Right-hand spiral flute with parallel web configuration promotes efficient chip removal

Compatibility

Designed as an OEM-grade replacement or direct application drill bit for CNC machining centers, manual drill presses, and screw machines requiring a 0.3268-inch (8.30 mm) carbide stub-length drill in the DIN 6537K Series 5510 standard.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Ensure the machine spindle is fully stopped and locked out before changing tooling. Seat the straight-cylindrical shank fully into the collet or chuck and torque the holder to the equipment manufacturer's specification. Verify coolant-through lines are clear and delivering adequate flow before beginning production cuts in hardened or high-alloy workpieces.
