Guhring 9055120075400 Taper Length Drill Bit 0.2969 in

Product Description

The GUHRING 9055120075400 is a solid carbide taper length drill bit designed for demanding precision drilling in metals and hard materials. Built to DIN 6537 standards, it features a 140-degree split point with a self-centering SU tip geometry and web-thinned, tapered web configuration for reduced entry force and improved chip evacuation. The spiral flute design and coolant-through capability make it well-suited for high-performance machining operations where heat management and consistent hole quality are critical. Licensed machinists and CNC operators working in production environments are the primary users of this tooling.

This drill bit is engineered for use across a broad range of difficult-to-machine materials including stainless steel, hardened materials, titanium alloy, nickel alloy, cast iron, brass, and general steel stock. Its 7xD flute-to-diameter ratio supports deeper hole applications without sacrificing rigidity. The straight shank with a 0.3150-inch shank diameter fits standard drill chucks and collet holders used in CNC machining centers and manual drilling setups alike. Series 5512 identifies the product family within the GUHRING line.

Key Features

• Solid submicron carbide construction for extended tool life in abrasive and hard materials
• 140-degree SU point with web thinning for self-centering entry and reduced thrust force
• Coolant-through design supports internal coolant delivery for heat control in deep-hole drilling
• Spiral flute geometry promotes efficient chip evacuation in interrupted and continuous cuts
• 7xD flute length ratio allows maximum drilling depth up to 2.547 inches (64.69 mm)
• DIN 6537 standard compliance ensures dimensional consistency and interchangeability

Compatibility

Designed as an OEM-style replacement and standard tooling option for CNC machining centers and drill presses requiring a straight-shank taper length carbide drill in the 19/64-inch diameter class.

Installation Notes

Installation and tool changes should be performed by qualified machinists with the spindle fully stopped and machine power locked out. Verify chuck or collet bore matches the 0.3150-inch shank diameter before seating the tool. When using the coolant-through feature, confirm that the machine spindle coolant system pressure is appropriate for the application before initiating the cycle. Inspect the cutting edge for wear or chipping before each use, as carbide tooling is brittle and susceptible to damage from improper handling.
