Guhring 9055100040000 Carbide Drill Bit 0.1575 in

Product Description

The GUHRING 9055100040000 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 4.00 mm (0.1575 inch) diameter bit features a 140-degree split point (SU type) with web thinning for reduced thrust and cleaner entry. The straight-cylindrical shank measures 6.00 mm in diameter and seats securely in standard chucks or collets. With coolant-through capability and a parallel web configuration, it is suited for high-cycle applications where heat management and hole quality are critical. Licensed machinists, tool-and-die technicians, and CNC operators are the primary installers.

This drill bit is engineered for cutting cast iron and steel. The screw machine length geometry keeps overhang short for improved rigidity, making it well-suited for CNC machining centers, turret lathes, and screw machine operations where repeatability and tight tolerances matter. The 3xD flute-to-diameter ratio supports chip evacuation in shallow-to-moderate depth holes. Maximum recommended drilling depth is 20.00 mm. The coated finish extends tool life in abrasive ferrous materials. This is a single-unit item with a package quantity of one.

Key Features

• Solid carbide construction with submicron carbide grade for high wear resistance
• 140-degree SU split point with web thinning reduces entry thrust and walking
• Coolant-through design supports internal coolant delivery for heat control
• Coated finish extends service life in cast iron and steel applications
• DIN 6537 K compliant screw machine length for rigid, low-overhang setups
• Right-hand cut with regular spiral flutes for efficient chip removal

Compatibility

Designed for use in cast iron and steel workpiece materials as an OEM-spec screw machine length drill bit conforming to DIN 6537 K. Primary workpiece materials listed in spec data are cast iron and steel.

Installation Notes

Installation and use should be performed by qualified machinists or CNC technicians familiar with carbide tooling. Before tool changes, power down the spindle and confirm the machine is in a safe state per shop lockout-tagout procedures. Carbide tooling is brittle — avoid side loads, interrupted cuts beyond the tool design, or re-chucking with contaminated collets. Verify coolant-through passages are clear and coolant pressure is appropriate for the machine before running at rated speeds.
