Guhring 9055110031700 Carbide Jobber Drill Bit 1/8 in

Product Description

The GUHRING 9055110031700 is a solid carbide jobber-length drill bit engineered for high-performance drilling in demanding materials. Built to DIN 6537L standards, it features a 140-degree split-point (SU) geometry with web thinning that promotes self-centering entry and reduces thrust force. The FIREX coating extends tool life in abrasive and high-heat applications. With a 1/8 inch (0.1250 inch decimal) cutting diameter and a straight-cylindrical shank measuring 0.2362 inches in diameter, this bit is suited for use in CNC machining centers, drill presses, and precision hand-held equipment. It is sold individually and weighs 0.05 pounds.

This drill bit is designed for cutting cast iron and steel, covering ISO material codes K and P. The Series 5511 platform targets production environments where tool consistency and hole quality matter. The 5xD flute-to-diameter ratio and 2-flute spiral configuration support chip evacuation in short to medium-depth holes. Coolant-through capability makes it compatible with through-spindle coolant systems, improving performance in continuous or high-cycle operations. Machinists, tool-and-die professionals, and maintenance technicians working in metalworking environments are the primary installers and operators.

Key Features

• Solid carbide submicron-grade construction for rigidity and wear resistance in hard materials
• FIREX coating for extended tool life in cast iron and steel applications
• 140-degree SU split-point with web thinning for self-centering, low-thrust entry
• Coolant-through design compatible with through-spindle coolant delivery systems
• Right-hand cut, regular spiral flute for efficient chip evacuation
• Conforms to DIN 6535 and DIN 6537 L standards for dimensional consistency

Compatibility

Designed for machining cast iron and steel workpieces (ISO material codes K and P). Compatible with machine tool spindles accepting a 0.2362-inch straight-cylindrical shank per DIN 6535. Suitable for CNC machining centers and drill presses equipped with through-spindle coolant capability.

Installation Notes

Installation and operation should be performed by qualified machinists familiar with carbide tooling procedures. Secure the straight-cylindrical shank firmly in a collet or drill chuck rated for the shank diameter before operation. Carbide tooling is brittle - avoid side loading, interrupted cuts without proper feed adjustments, or dropping the bit, as these actions can cause chipping or fracture. Verify spindle speed and feed rate against the material being drilled; consult the tooling manufacturer feed-and-speed tables for cast iron and steel at this diameter.
