Guhring 9055120065300 Taper Length Drill Bit 0.2570 in

Product Description

The GUHRING 9055120065300 is a solid carbide taper length drill bit designed for precision drilling in demanding industrial and trade applications. Built to DIN 6537 standards, it features a 140-degree split-point (SU) tip with web thinning for self-centering entry without a pilot hole. The 0.2570-inch diameter bit runs a 7xD flute-to-diameter ratio, giving it the reach needed for deeper bores while maintaining rigidity. Coolant-through capability supports high-speed operation in difficult materials. Right-hand spiral flutes evacuate chips efficiently, reducing heat buildup and extending tool life in production drilling environments.

This bit is suited for drilling brass, cast iron, hardened materials, nickel alloys, stainless steel, steel, and titanium alloy. The straight shank and 0.3150-inch shank diameter make it compatible with standard drill chucks and collet holders used in CNC machining centers, drill presses, and manual production setups. It is a Series 5512 tool, appropriate for shops and field machinists who need a reliable, coated carbide drill in the F letter-size range for tight-tolerance work.

Key Features

• Solid carbide construction with submicron-grade material for hardened and exotic alloy drilling
• 140-degree SU point geometry with web thinning for self-centering, no pilot hole required
• Coolant-through design supports high-speed and high-feed drilling cycles
• 7xD flute length ratio provides extended reach with controlled chip evacuation
• Coated finish for improved wear resistance and reduced friction
• Conforms to DIN 6537 standards for dimensional consistency

Compatibility

Designed for use in standard straight-shank drill chucks and collet systems; compatible with material applications including brass, cast iron, hardened materials, nickel alloy, stainless steel, steel, and titanium alloy as specified by the manufacturer for Series 5512.

Installation Notes

Installation and use should be performed by a qualified machinist or tooling professional. Ensure the machine spindle and chuck are fully stopped and locked out before inserting or removing the bit. Verify chuck or collet bore size accommodates the 0.3150-inch shank diameter before seating. When using coolant-through capability, confirm the machine spindle is equipped for through-spindle coolant delivery at the appropriate pressure for the material being drilled.
