Guhring 9055120060000 Taper Length Drill Bit 0.2362 in

Product Description

The GUHRING 9055120060000 is a solid carbide taper length drill bit designed for demanding material removal in professional machining and fabrication environments. Built to DIN 6537 standards, it features a 140-degree split point (SU type) with web thinning for self-centering entry and reduced thrust. The 7xD flute-to-diameter ratio supports deeper bore passes at 0.2362 inches (6.00 mm) diameter with a maximum drilling depth of 1.89 inches (48.00 mm). A coated finish protects the cutting edges against wear and heat buildup. Licensed machinists, tool-and-die technicians, and CNC operators working in high-production shops are the primary installers of this tool class.

This drill bit is engineered for use across a broad range of challenging workpiece materials including steel, stainless steel, cast iron, hardened materials, brass, nickel alloy, and titanium alloy. The coolant-through design channels cutting fluid directly to the tip, making it well-suited for CNC machining centers and drill presses equipped with through-spindle coolant delivery. The straight shank and standard 0.2362-inch shank diameter provide direct compatibility with collet chucks and keyed drill chucks of the corresponding bore size. Series 5512 taper length geometry provides added reach compared to jobber-length configurations for applications requiring clearance depth.

Key Features

• Solid submicron carbide construction for extended tool life in hard and abrasive materials
• 140-degree SU split point with web thinning enables self-centering entry without a pilot hole
• Coolant-through design supports high-speed CNC operations with through-spindle coolant
• Coated finish reduces friction and heat at the cutting edge
• 7xD flute-to-diameter ratio accommodates deeper bores in a single operation
• Conforms to DIN 6537 standard for consistent dimensional accuracy

Compatibility

Designed as a Series 5512 taper length replacement or direct-application drill bit for CNC machining centers, drill presses, and manual lathes equipped with collet or keyed chuck systems accepting a 0.2362-inch straight shank. Suitable for workpiece materials including brass, cast iron, hardened materials, nickel alloy, stainless steel, steel, and titanium alloy.

Installation Notes

Installation and operation of this drill bit should be performed by qualified machinists or CNC technicians familiar with cutting tool setup and safe machine operation. Ensure the spindle is fully stopped and the machine is locked out before inserting or removing the bit from the chuck or collet. Verify runout and chuck concentricity before beginning a drilling cycle to avoid premature edge wear or bit breakage. When using coolant-through capability, confirm that system pressure and flow rate are within the machine manufacturer specifications before engaging the spindle.
