Guhring 9055110145000 Carbide Jobber Drill Bit 0.5709 in

Product Description

The GUHRING 9055110145000 is a solid carbide jobber length drill bit engineered for demanding precision drilling applications. It features a 0.5709 inch diameter, a 140 degree split point (SU type), and a FIREX coating that improves wear resistance and tool life in abrasive and hard materials. The overall length is 5.2362 inches (133 mm), with a flute length of 3.2677 inches (83 mm). Designed to DIN 6537L specification, this bit is built to tight diameter tolerances of 0.007 to 0.025 mm. It is intended for use by machinists, toolmakers, and precision metalworking professionals who require consistent, repeatable hole quality in production environments.

This drill bit is suited for CNC machining centers, drill presses, and manual machines operating in job shop, aerospace, automotive, and general metalworking settings. The 5xD flute-to-diameter ratio supports jobber length reach across a broad range of workpiece thicknesses. The straight-cylindrical shank with a diameter of 0.6299 inches fits standard collets and drill chucks without modification. Internal coolant-through capability allows cutting fluid delivery directly to the cutting edge, making this bit effective in high-speed production runs where heat management is critical.

Key Features

• Solid submicron carbide construction for high hardness and dimensional stability
• FIREX coating provides enhanced wear resistance in abrasive and hard workpiece materials
• 140 degree SU split point reduces thrust force and improves self-centering on entry
• Coolant-through design delivers fluid directly to the cutting zone for heat and chip control
• Web-thinned tapered web reduces cutting resistance and improves chip evacuation
• Right-hand spiral flute with regular helix, conforming to DIN 6537L

Compatibility

Designed as a jobber length replacement or production drill for applications requiring a 0.5709 inch diameter hole, fitting standard straight-shank collets and drill chucks accepting a 0.6299 inch shank diameter, within the 0.5000 to 0.6500 inch drill bit size range.

Installation Notes

Installation and use should be performed by qualified machinists familiar with CNC or manual machine tooling. Ensure the machine spindle and chuck or collet are fully de-energized and at a complete stop before inserting or removing the bit. Verify the shank is fully seated and the chuck or collet is tightened to the machine manufacturer specifications before operation. Coolant-through setups should be confirmed leak-free and at the correct pressure for the machine before cycling.
