Guhring 9055110039700 Carbide Jobber Drill Bit 5/32

Product Description

The GUHRING 9055110039700 is a solid carbide jobber-length drill bit designed for high-performance drilling in demanding production and maintenance environments. Built to DIN 6537 L and DIN 6535 standards, this bit features a 140-degree split-point (SU) tip geometry and FIREX coating for extended tool life in abrasive materials. The 5/32 inch (0.1562 inch) diameter shank is straight-cylindrical at 0.2362 inch shank diameter, and the overall length is 74 millimeters (approximately 2.91 inches). It is self-centering and web-thinned for reduced thrust force at entry. Licensed HVAC technicians, machinists, and metalworking tradespeople regularly specify carbide-grade tooling like this for tight-tolerance hole production.

This drill bit is engineered for primary use in cast iron and steel workpiece materials, making it well-suited for production drilling on ferrous components in fabrication shops, maintenance facilities, and manufacturing lines. The 5xD flute-to-diameter ratio supports chip evacuation in deeper hole applications, with a maximum drilling depth of 30.05 millimeters (1.183 inches). Internal coolant-through capability allows it to run in CNC machining centers and drill presses equipped with through-spindle coolant, improving chip flushing and thermal management in high-cycle operations. It ships individually in single-piece packaging.

Key Features

• Solid submicron carbide construction for rigidity and wear resistance in ferrous materials
• FIREX coating provides thermal and oxidation resistance for extended tool life
• 140-degree SU point is self-centering and web-thinned to reduce entry thrust
• Coolant-through design compatible with through-spindle coolant systems
• Spiral flute with regular helix and tapered web for consistent chip evacuation
• Conforms to DIN 6537 L and DIN 6535 standards for dimensional consistency

Compatibility

Designed as an OEM-spec replacement or direct-application carbide jobber drill for use in CNC machining centers, drill presses, and similar equipment configured for straight-cylindrical shank tooling in the DIN 6535 standard shank format.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician familiar with carbide tooling handling practices. Secure the straight-cylindrical shank in a properly sized collet or drill chuck, ensuring full shank engagement before running. Always verify spindle speed and feed rate recommendations for carbide tooling in the specific workpiece material before operation. Do not use carbide bits in hand-held drills or applications with excessive runout, as carbide is brittle and can fracture under lateral loading.
