Guhring 9055120123000 Taper Length Drill Bit 0.4844 in

Product Description

The GUHRING 9055120123000 is a solid carbide taper length drill bit designed for demanding material removal applications in professional machining environments. Built to DIN 6537 standards, this bit features a 140-degree point angle with a self-centering SU point type and a web-thinned, tapered web configuration for reduced thrust and improved chip evacuation. The 31/64-inch (0.4844-inch) diameter bit runs a right-hand spiral flute with coolant-through capability, making it suited for CNC and manual drilling operations where heat management and hole quality are critical. Machinists, tool and die professionals, and production shop operators are the primary users of this tool.

This drill bit is engineered for use across a broad range of difficult-to-machine materials including stainless steel, hardened materials, nickel alloy, titanium alloy, cast iron, steel, and brass. Its 7xD flute-length-to-diameter ratio and 4.51-inch maximum drilling depth support deep-hole applications where chip clearance and tool rigidity are priorities. The straight shank and 0.5512-inch shank diameter allow for secure chuck or collet clamping in standard drill presses, machining centers, and CNC lathes.

Key Features

• Solid carbide submicron-grade construction for wear resistance in hard and abrasive materials
• 140-degree SU point angle with self-centering geometry reduces walking and improves entry accuracy
• Web-thinned tapered web lowers thrust requirements on harder workpieces
• Coolant-through design supports high-speed deep-hole drilling with active chip and heat control
• 7xD flute ratio with maximum drilling depth of 4.51 inches handles deep-reach applications
• Built to DIN 6537 standards for consistent dimensional accuracy and interchangeability

Compatibility

Designed as a Series 5512 taper length drill bit intended for use with standard straight-shank drill chucks and collet systems that accept a 0.5512-inch shank diameter. Suitable for CNC machining centers, manual drill presses, and lathes configured for coolant-through tooling.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the machine spindle is fully stopped and locked out before inserting or removing the bit from the chuck or collet. Verify that the coolant-through passages in the spindle are clear and compatible before activating coolant flow. Follow the tool manufacturer and machine builder guidelines for feed rate and spindle speed selection based on workpiece material.
