Guhring 9055120105000 Taper Length Drill Solid Carbide

Product Description

The GUHRING 9055120105000 is a solid carbide taper length drill engineered for high-performance drilling in demanding materials. Carrying a 140-degree point angle with a self-centering SU point geometry, this drill is purpose-built to enter hard and abrasive workpieces cleanly without walking. The TiAlN coating provides thermal resistance and extended tool life at elevated cutting speeds. A coolant-through design delivers cutting fluid directly to the tip, supporting chip evacuation and heat control during deep-hole operations. At 10.50 mm (0.4134 inches) in diameter with a 7xD flute-to-diameter ratio, the 9055120105000 is suited for production environments where consistent hole quality and tool life are critical.

This drill is intended for use in metalworking and machining applications across a wide range of materials including steel, stainless steel, cast iron, nickel alloy, titanium alloy, brass, and hard materials. The straight-cylindrical shank seats directly into standard drill chucks and collet systems. With a maximum drilling depth of 3.553 inches (90.25 mm), it handles through-holes and blind-holes in both jobshop and production CNC setups. The web-thinned, tapered web configuration reduces thrust force at entry. Series 5512 conforms to DIN 6537.

Key Features

• Solid carbide construction in submicron grain material grade for rigidity and edge retention
• TiAlN coating for high-temperature resistance and extended service life
• 140-degree SU point angle with web thinning for self-centering entry and reduced thrust
• Coolant-through design supports chip evacuation and thermal management in deep holes
• 7xD flute length ratio (flute length 106 mm, 4.173 inches) for extended reach applications
• Right-hand spiral flute with straight-cylindrical shank compatible with standard toolholding systems
• Conforms to DIN 6537 standard

Compatibility

Designed for use in steel, stainless steel, cast iron, nickel alloy, titanium alloy, brass, and hard materials. Compatible with standard straight-bore drill chucks and collet holders accepting a 0.4724-inch shank diameter. Series 5512 per DIN 6537.

Installation Notes

Installation and operation should be performed by a qualified machinist or toolroom professional. Ensure the shank is fully seated and properly torqued in the toolholder before use. Verify coolant-through connections are active and delivering adequate flow before initiating deep-hole cycles. Do not exceed the rated maximum drilling depth of 3.553 inches without re-evaluating chip evacuation and coolant pressure.
