Guhring 9085100100000 Screw Machine Drill Bit 10mm

Product Description

The GUHRING 9085100100000 is a solid carbide screw machine length drill bit engineered for high-performance drilling in demanding materials. Built to DIN 6537 K standards, this Series 8510 bit features a 140-degree facet point and a web-thinned, tapered web configuration that reduces entry force and improves chip evacuation. The nano-A multi-layer coating extends tool life when cutting stainless steel and high-temperature alloys. With a 10 mm diameter and an overall length of 3.504 inches (89 mm), it delivers a compact, rigid setup suited for machine tool applications requiring tight tolerances.

This drill bit is designed for CNC machining centers, drill presses, and screw machine operations where precise, repeatable hole quality is required. Its primary target materials are stainless steel and high-temperature alloys, making it a common choice in aerospace, medical device, and industrial manufacturing environments. The straight cylindrical shank seats securely in standard drill chucks or collet holders. The 3xD flute-to-diameter ratio and coolant-through capability support high-feed drilling cycles with active chip flushing.

Key Features

• Solid carbide construction in DK460UF grade for rigidity and wear resistance in hard and abrasive materials
• nano-A multi-layer proprietary coating reduces friction and extends tool life in stainless steel and high-temp alloys
• 140-degree facet point with web thinning reduces thrust and improves self-centering on entry
• Coolant-through design supports internal coolant delivery for deep-hole and high-feed applications
• DIN 6537 K standard ensures dimensional consistency and drop-in compatibility with standard toolholders
• Diameter tolerance of +0.006 to +0.021 mm supports close-tolerance hole applications

Compatibility

Designed as a screw machine length drill bit per DIN 6537 K, compatible with standard straight-shank drill chucks and collet systems accepting a 10 mm shank diameter. Suited for CNC and conventional machine tools equipped with internal coolant supply.

Installation Notes

Installation and tool changes should be performed by a qualified machinist or tooling technician with the machine powered down and locked out per facility LOTO procedures. Ensure the shank is fully seated and the collet or chuck is torqued to the toolholder manufacturer specification before operation. Verify coolant-through passages are clear and active coolant pressure is confirmed before initiating drilling cycles in stainless or high-temp alloy workpieces. Do not use this bit freehand or in handheld drilling equipment.
