Guhring 9055120055000 Taper Length Drill Bit 0.2165 in

Product Description

The GUHRING 9055120055000 is a solid carbide taper length drill bit engineered for demanding metalworking applications. It carries a 0.2165-inch (5.50 mm) cutting diameter, a 140-degree split point angle, and a web-thinned, tapered web configuration that promotes self-centering entry without a center punch. The spiral flute geometry is optimized for chip evacuation, and the coated finish extends tool life when cutting abrasive and hard materials. Coolant-through capability delivers cutting fluid directly to the tip, reducing heat buildup during deep-hole operations. This bit is sized at 7xD flute-to-diameter ratio and is aimed at machinists and toolroom technicians working in production or job-shop environments.

This drill bit is suited for right-hand cutting in a wide range of materials including steel, stainless steel, cast iron, hardened materials, nickel alloy, titanium alloy, and brass. The straight shank fits standard drill chucks and collet holders. With a maximum drilling depth of 1.919 inches (48.75 mm) and an overall length of 3.819 inches (97.00 mm), it handles through-hole and blind-hole work in both manual and CNC machining setups. It is manufactured to DIN 6537 standards and is sold as a single unit.

Key Features

• Solid carbide submicron-grade construction for rigidity and edge retention in hard and abrasive materials
• 140-degree SU point with web thinning enables self-centering entry and reduces thrust force
• Coolant-through design directs fluid to the cutting edge for heat control during deep-hole drilling
• 7xD flute length ratio supports deeper holes relative to diameter without peck drilling
• Coated finish extends cutting life across high-temperature alloys and stainless steel
• Straight shank with 0.2362-inch shank diameter fits standard toolholders and collets

Compatibility

Designed for use in CNC machining centers, drill presses, and manual lathes equipped with standard straight-shank toolholders or collet chucks. Compatible material applications include brass, cast iron, hardened materials, nickel alloy, stainless steel, steel, and titanium alloy as stated by the manufacturer.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Secure the straight shank fully in a collet or drill chuck before operation and verify runout is within acceptable limits for the application. Activate coolant-through supply before engaging the cut to protect the tool tip. Do not exceed the rated maximum drilling depth of 1.919 inches per pass without re-evaluating chip clearance and cutting parameters.
