Guhring 9055140044000 Carbide Screw Machine Drill Bit 0.1732in

Product Description

The GUHRING 9055140044000 is a solid carbide screw machine length drill bit designed for high-performance drilling in demanding production environments. Built to DIN 6537 K standards, this Series 5514 bit features a 140-degree split point (SU point type) with web thinning for reduced thrust and faster entry. The straight-cylindrical shank and regular spiral flute geometry promote chip evacuation and consistent hole quality. At 0.1732 inches in diameter with a coated finish, this bit is suited for right-hand cutting in cast iron and steel applications where precision and tool life are critical priorities.

This drill bit is intended for use in screw machine operations, CNC drilling centers, and production drilling setups where short, rigid tooling is required. The screw machine length format provides added stiffness compared to jobber-length bits, making it well suited for high-cycle production work in cast iron and steel. A maximum drilling depth of 0.6850 inches and a flute-to-diameter ratio of 3xD support controlled chip removal in shallow-to-medium depth holes. Licensed machinists, toolroom technicians, and CNC operators are the typical end users.

Key Features

• Solid carbide submicron grain construction for extended tool life in ferrous materials
• 140-degree SU split point with web thinning reduces entry thrust and walking
• Coated finish improves wear resistance and surface lubricity
• Regular spiral flute with parallel web configuration supports consistent chip flow
• DIN 6537 K specification ensures dimensional conformance for toolholder compatibility
• Screw machine length for maximum rigidity in production drilling applications

Compatibility

Designed as an OEM-style replacement or direct tooling selection for straight-cylindrical shank drill chucks and collet holders accepting a 0.1732-inch diameter screw machine length drill bit; primary workpiece materials are cast iron and steel.

Installation Notes

Install in a compatible straight-shank drill chuck or collet holder and verify that runout is within acceptable tolerance before production use. Ensure the drilling machine spindle is fully stopped and the workpiece is securely fixtured before bit changes. Coolant-through is not supported on this bit; apply external coolant or cutting fluid as appropriate for the workpiece material and cutting parameters. Follow applicable shop safety standards and machine manufacturer guidelines for carbide tooling handling and storage.
