Guhring 9055100091000 Screw Machine Drill Bit Carbide

Product Description

The GUHRING 9055100091000 is a solid carbide screw machine length drill bit designed for high-performance drilling in demanding production environments. Built to DIN 6537K standards, this bit features a 140-degree split point with SU point geometry and web thinning for fast, accurate starts without a center punch. The 9.10 mm (0.3583 inch) diameter, two-flute spiral design with coated finish supports aggressive feed rates in hard and abrasive materials. Coolant-through capability makes it well-suited for high-volume or deep-hole applications where heat and chip evacuation are critical concerns. Licensed machinists, toolroom technicians, and CNC operators are the primary users of this tool.

This drill bit is intended for use in cast iron and steel workpieces, making it a practical choice for production machining, job shop work, and precision component manufacturing. The screw machine length format provides rigidity and reduced deflection compared to jobber-length bits, which is especially useful in CNC machining centers and turret lathes where stub-length control is advantageous. The straight-cylindrical shank seats securely in standard drill chucks and collet systems without modification.

Key Features

• Solid carbide construction for extended tool life in ferrous materials
• 140-degree SU split point with web thinning for self-centering starts
• Coolant-through design for efficient chip evacuation and heat control
• Coated finish to reduce friction and extend cutting edge life
• DIN 6537K standard compliance for consistent dimensional accuracy
• Screw machine length body for increased rigidity and reduced runout

Compatibility

Designed as an OEM-style production drill for use in cast iron and steel applications; fits standard straight-cylindrical drill chucks and collet holders accepting a 10.00 mm shank diameter.

Installation Notes

Installation and use of this drill bit should be performed by qualified machinists or CNC technicians familiar with carbide tooling handling requirements. Ensure the machine spindle is fully stopped and locked out before inserting or removing the bit from the chuck or collet. Carbide tooling is brittle and should not be subjected to side-loading, interrupted cuts beyond its design rating, or impact that can cause chipping. Verify coolant flow is active before beginning a drilling cycle when using the coolant-through feature.
