Guhring 9085100038000 Carbide Screw Machine Drill Bit

Product Description

The GUHRING 9085100038000 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 VA point angle, web-thinned geometry, and coolant-through capability for efficient chip evacuation and heat management. At 0.1495 inches (wire size #25) in diameter with a straight-cylindrical shank of 6.00 mm, it delivers tight dimensional tolerances to m7 specification. It is installed by machinists, tool and die technicians, and precision manufacturing professionals working in CNC and manual drilling operations.

This drill bit is designed for primary use in titanium alloy workpieces, where controlled point geometry and coolant delivery are critical to tool life and hole quality. The screw machine length profile, shorter than jobber length, provides added rigidity in close-tolerance setups and short-reach applications. With a 3xD flute-to-diameter ratio and a maximum drilling depth of 0.72 inches (18.30 mm), it suits precision hole-making in aerospace, medical device, and high-value manufacturing environments where material integrity cannot be compromised.

Key Features

• Solid carbide construction rated for titanium alloy and other high-performance workpiece materials
• 140-degree VA split point reduces walking and lowers thrust force at entry
• Web-thinned geometry supports consistent chip flow and reduces cutting resistance
• Coolant-through design delivers cutting fluid directly to the cutting edge for thermal control
• DIN 6537 K standard compliance ensures dimensional and geometric consistency
• Straight-cylindrical shank compatible with standard drill chucks and collet holders

Compatibility

Designed as a high-performance screw machine length drill for use in titanium alloy and comparable difficult-to-machine materials; fits standard straight-shank drill chucks and ER-style collet systems accepting a 6.00 mm shank diameter.

Installation Notes

Installation and use of solid carbide drill bits should be performed by qualified machinists or CNC technicians familiar with tooling setup and cutting parameters. Ensure the machine spindle is fully stopped and locked out before mounting or removing the tool. Verify chuck or collet runout is within acceptable limits, as carbide is brittle and sensitive to lateral loading. Coolant-through tooling requires a compatible machine spindle with internal coolant delivery for optimal performance.
