Guhring 9055140035000 Carbide Screw Machine Drill Bit

Product Description

The GUHRING 9055140035000 is a solid submicron carbide screw machine length drill bit engineered for high-performance drilling in ferrous materials. Built to DIN 6537 K standards, it features a 140-degree split point (SU), a web-thinned parallel web, and a regular spiral flute geometry that promotes efficient chip evacuation. The 3.50 mm cutting diameter is ground to a tight tolerance of +0.004 to +0.016 mm, delivering consistent hole quality in production environments. Licensed machinists, toolroom technicians, and CNC operators install this bit for short-run and production drilling applications demanding dimensional accuracy and tool longevity.

This drill bit is designed for drilling cast iron and steel workpieces. Its screw machine length body keeps overhang minimal, improving rigidity and reducing deflection in drill press, CNC machining center, and lathe tail-stock applications. The straight-cylindrical shank with a 6.00 mm diameter seats securely in standard collet chucks and drill chucks without special adapters. Maximum drilling depth reaches 14.75 mm, and the 20.00 mm flute length accommodates the full depth range within the screw machine envelope. It suits both intermittent and continuous production cycles where tool life and hole-position accuracy are priorities.

Key Features

• Solid submicron carbide construction for extended tool life in hard and abrasive ferrous materials
• 140-degree SU split point reduces thrust force and self-centers on entry without a pilot hole
• Web-thinned parallel web lowers cutting resistance and improves chip flow
• Regular spiral flute with 3xD flute-to-diameter ratio clears chips efficiently at full depth
• Coated finish enhances wear resistance and reduces built-up edge on steel
• Meets DIN 6537 K specification for consistent dimensional interchangeability

Compatibility

Designed as a DIN 6537 K screw machine length carbide drill bit suited for use in cast iron and steel workpieces; compatible with any standard drill press, CNC machining center, or lathe tail-stock equipped with a collet or drill chuck accepting a 6.00 mm straight-cylindrical shank.

Installation Notes

This tool is installed by machinists or CNC toolroom technicians. Before changing tooling, de-energize and lock out the machine spindle per applicable machine safety procedures. Seat the straight-cylindrical shank fully in a properly sized collet or drill chuck and verify runout before cycling. No coolant-through capability is present on this bit, so ensure adequate external coolant or cutting fluid flow when drilling steel at production feeds and speeds.
