Guhring 9055140033000 Carbide Screw Machine Drill Bit

Product Description

The GUHRING 9055140033000 is a solid carbide screw machine length drill bit designed for high-performance drilling in demanding production environments. Built to DIN 6537 K standards, it features a 140-degree split point (SU geometry) with web thinning for reduced thrust and cleaner entry. The two-flute spiral configuration and coated finish support fast chip evacuation and extended tool life. At 0.1299 inches in diameter with a straight-cylindrical shank, this bit is sized for precision work in cast iron and steel applications. Licensed machinists, tool-room technicians, and CNC operators are the typical end users.

This drill bit fits screw machine length applications where a compact, rigid tool is required for close-tolerance drilling in cast iron and steel. The 3xD flute-to-diameter ratio and parallel web configuration make it well-suited for short-reach, high-repeatability operations on CNC machining centers, drill presses, and production lathes. Its submicron carbide grade provides the hardness needed for abrasive ferrous materials without sacrificing edge integrity at higher spindle speeds.

Key Features

• Solid submicron carbide construction for rigidity and wear resistance in ferrous materials
• 140-degree SU point geometry with web thinning reduces entry thrust and minimizes workpiece deformation
• Coated finish extends tool life in cast iron and steel cutting applications
• Straight-cylindrical shank fits standard collet chucks and drill sleeves
• DIN 6537 K specification ensures dimensional consistency and interchangeability
• Maximum drilling depth of 0.593 inches supports standard production hole depths

Compatibility

Designed for use in cast iron and steel workpieces; fits standard straight-shank toolholders and collet systems accepting a 6 mm shank diameter, consistent with DIN 6537 K screw machine length drill bit specifications.

Installation Notes

Installation and tool changes should be performed by qualified machinists with the machine powered down and spindle locked. Ensure the collet or chuck is clean and undamaged before seating the shank to prevent runout. Verify spindle speed and feed rate are appropriate for the workpiece material before engaging the cut. Coolant-through is not supported on this bit, so adequate external coolant or lubrication should be applied when drilling steel at sustained depths.
