Guhring 9055120135000 Taper Length Drill Bit 0.5315 in

Product Description

The GUHRING 9055120135000 is a solid carbide taper length drill bit engineered for demanding material removal in production and job-shop 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-length-to-diameter ratio and through-coolant capability make it well-suited for deep-hole operations in difficult materials. At 0.5315 inches in diameter with a straight shank measuring 0.5512 inches, it mounts directly in standard drill chucks or collet holders without an adapter. The spiral flute geometry promotes efficient chip evacuation throughout the full cutting depth.

This drill bit is designed for right-hand cutting in a broad range of difficult-to-machine materials including stainless steel, hardened materials, nickel alloy, titanium alloy, cast iron, brass, and steel. It is suited for CNC machining centers, drill presses, and manual machines where through-coolant is available. The 7xD reach allows drilling to a maximum depth of 4.439 inches (112.75 mm) in a single pass, making it a practical choice for deep-hole work that would otherwise require peck drilling with shorter tooling. Machinists and toolroom professionals working in aerospace, medical, and general metalworking applications will find this geometry particularly efficient.

Key Features

• Solid submicron carbide construction for hardness and wear resistance in difficult materials
• 140-degree SU point with web thinning for self-centering and reduced entry thrust
• Through-coolant capable, supporting extended tool life in deep-hole applications
• 7xD flute length allows drilling to 4.439 inches without tool change
• Right-hand spiral flute geometry promotes consistent chip evacuation
• Built to DIN 6537 standard for dimensional and performance consistency

Compatibility

Designed as an OEM-style replacement or direct-fit solid carbide drill for applications requiring a 0.5315-inch diameter, straight-shank taper length drill conforming to DIN 6537 and Series 5512 specifications. Compatible with materials including brass, cast iron, hardened materials, nickel alloy, stainless steel, steel, and titanium alloy as specified by the manufacturer.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Ensure the machine spindle and any collet or chuck is fully stopped and locked out before loading or changing tooling. Verify shank seating depth and runout with a dial indicator before cutting, as carbide tooling is sensitive to misalignment and can fracture under lateral load. Always confirm through-coolant pressure and flow are set per your machine specifications before engaging the cut.
