Guhring 9055110102000 Carbide Jobber Drill Bit 0.4016in

Product Description

The GUHRING 9055110102000 is a solid carbide jobber-length drill bit designed for high-performance drilling in ferrous materials. Built to DIN 6537 L standards, it features a 140-degree split point (SU type) with web thinning for self-centering entry without a center punch. The FIREX coating adds thermal and wear resistance, extending tool life in demanding production environments. At 4.6457 inches overall length with a 2.7953-inch flute length, this bit operates in a 5xD flute-to-diameter ratio configuration. Coolant-through capability supports high-speed drilling cycles where chip evacuation and heat control are critical. This is a precision tool for machinists, toolroom technicians, and CNC operators.

Engineered for primary use in cast iron and steel workpieces, this bit fits standard production and toolroom drilling applications in metalworking shops and manufacturing facilities. The straight-cylindrical shank at 0.4724 inches diameter seats securely in drill chucks and collet systems. A maximum drilling depth of 2.1930 inches (55.70 mm) makes it suitable for through-holes and blind bores in typical structural and component stock. The regular spiral flute geometry promotes consistent chip flow in both through-coolant and dry-drilling setups.

Key Features

• Solid carbide submicron-grade construction for hardness and edge retention in steel and cast iron
• FIREX coating provides heat and wear resistance for extended tool life in high-cycle operations
• 140-degree SU split point with web thinning enables self-centering entry without spotting
• Coolant-through design supports high-speed drilling with active chip and heat management
• DIN 6537 L and DIN 6535 compliant geometry ensures dimensional consistency and interchangeability
• Straight-cylindrical shank compatible with standard drill chucks and collet holders

Compatibility

Designed for use in metalworking drilling applications targeting cast iron and steel workpieces. Conforms to DIN 6537 L specification, making it dimensionally interchangeable with other DIN-compliant tooling systems. Compatible with any machine spindle or chuck accepting a 0.4724-inch straight-cylindrical shank.

Installation Notes

Installation and tool changes should be performed by qualified machinists or toolroom personnel with the machine fully de-energized and spindle locked. Verify chuck or collet runout before seating the bit to protect the carbide shank from lateral stress. Coolant-through setups should be pressure-tested and purged before initiating a drilling cycle. Avoid side loading or interrupted cuts beyond the design parameters, as solid carbide is brittle under unexpected lateral force.
