Guhring 9055120095200 Taper Length Drill Bit 3/8 in

Product Description

The GUHRING 9055120095200 is a solid carbide taper length drill bit designed for demanding industrial drilling applications. Built to DIN 6537 standards, it features a 140-degree split point (SU) geometry with web thinning for self-centering entry and reduced thrust. The 7xD flute-length-to-diameter ratio provides extended reach while maintaining rigidity. Coolant-through capability supports high-speed, deep-hole drilling in difficult-to-machine materials. This bit is intended for use by machinists, tool and die makers, and CNC operators working in aerospace, oil and gas, automotive, and general metalworking environments.

The 9055120095200 is rated for drilling brass, cast iron, hardened materials, nickel alloy, stainless steel, steel, and titanium alloy. Its coated, submicron-grade carbide substrate resists heat and wear in interrupted cuts and abrasive materials. The straight shank and consistent 0.3937-inch shank diameter allow direct installation in standard drill chucks, collet holders, and hydraulic toolholders commonly used on CNC machining centers and drill presses.

Key Features

• Solid submicron carbide construction for extended tool life in hard and abrasive materials
• 140-degree SU point with web thinning for self-centering entry and low thrust force
• Coolant-through design supports chip evacuation and heat control in deep-hole drilling
• 7xD flute length provides a maximum drilling depth of approximately 3.178 inches (80.72 mm)
• Tapered web configuration adds core strength along the flute length
• Conforms to DIN 6537 standards for dimensional consistency and interchangeability

Compatibility

Designed as a Series 5512 taper length drill bit for use in standard straight-shank toolholders, collet chucks, and drill chucks sized for a 0.3937-inch shank diameter. Suitable for CNC machining centers and conventional drill presses where coolant-through capability is available.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Secure the straight shank fully into the toolholder to the recommended gauge-line depth before tightening to prevent runout. Verify that the machine spindle and coolant-through system are disabled before loading or changing tooling. Follow shop-floor speeds and feeds guidelines for the specific workpiece material, as carbide tooling is sensitive to incorrect parameters and interrupted cuts without proper support.
