Guhring 9055120142900 Taper Length Drill Bit 9/16 in

Product Description

The GUHRING 9055120142900 is a solid carbide taper length drill bit from the Series 5512 line, designed for high-performance drilling in demanding industrial and metalworking applications. Built to DIN 6537 standards, it features a 140-degree point angle with a SU point type and web-thinned, tapered web geometry for self-centering entry and reduced thrust. The TiAlN coating provides thermal resistance and extended tool life when cutting hard and abrasive materials. A coolant-through design channels cutting fluid directly to the cutting edge, supporting deeper hole operations. This bit is intended for use by machinists and toolroom professionals requiring precise, repeatable results in tough workpiece materials.

This drill bit is suited for production and job-shop environments where difficult materials are machined. It handles a broad range of workpiece materials including steel, stainless steel, cast iron, nickel alloy, titanium alloy, brass, and hard materials. The straight cylindrical shank seats in standard drill chucks and collet holders. With a 7xD flute-length-to-diameter ratio and a maximum drilling depth of 130.57 mm (5.141 inches), it is well matched to taper-length drilling operations where standard jobber bits lack the reach or rigidity required.

Key Features

• Solid carbide submicron-grade construction for rigidity and wear resistance
• TiAlN coating for high-heat and hard-material applications
• 140-degree point angle with SU point type for self-centering and reduced thrust
• Coolant-through design supports deep-hole drilling and chip evacuation
• Web-thinned tapered web geometry reduces cutting forces at entry
• Right-hand spiral flute for standard CNC and manual spindle use
• Conforms to DIN 6537 dimensional standard

Compatibility

Designed for use in steel, stainless steel, cast iron, nickel alloy, titanium alloy, brass, and hard materials. Compatible with standard straight-bore drill chucks and collet holders accepting a 0.6299-inch shank diameter.

Installation Notes

Installation and use should be performed by qualified machinists familiar with CNC or manual drilling operations. Ensure the spindle is fully stopped and the machine is locked out before mounting or removing the bit. Verify the chuck or collet is rated for the 0.6299-inch shank diameter and that runout is within acceptable tolerance before beginning a cut. Do not exceed the recommended maximum drilling depth of 130.57 mm without retracting to clear chips.
