Guhring 9055140049000 Screw Machine Drill Bit 0.1929in

Product Description

The GUHRING 9055140049000 is a solid carbide screw machine length drill bit designed for high-performance drilling in ferrous materials. Built to DIN 6537 K standards, it features a 140-degree split point (SU type) with web thinning for fast, accurate penetration and reduced thrust. The 0.1929-inch diameter and short screw machine length make it well-suited for precision drilling in confined setups or on automatic screw machines. With a regular spiral flute and straight-cylindrical shank, this bit is compatible with standard drill chucks and collet holders used across machining operations. It weighs approximately 0.05 pounds.

This drill bit is intended for production and maintenance machining environments where tight tolerances and clean entry holes are required. Primary workpiece materials include cast iron and steel. The 3xD flute-to-diameter ratio and 20.65 mm maximum drilling depth make it appropriate for shallow to mid-depth hole applications. It is typically used by machinists, tool and die technicians, and maintenance mechanics working on CNC machines, drill presses, or automatic screw machines where consistent hole quality is critical.

Key Features

• Solid carbide submicron-grade construction for extended tool life in hard ferrous materials
• 140-degree SU split point with web thinning reduces walking and lowers drilling thrust
• Right-hand cut, regular spiral flute geometry for efficient chip evacuation
• Straight-cylindrical shank fits standard drill chucks and collet holders
• Meets DIN 6537 K specification for consistent dimensional accuracy
• Diameter tolerance of +0.004 to +0.016 mm for precise hole sizing

Compatibility

Designed as an OEM-style replacement and standard tooling option for screw machine and CNC drilling applications requiring a 0.1929-inch solid carbide drill bit in the DIN 6537 K form factor. Compatible with workpieces in cast iron and steel.

Installation Notes

Installation and use should be performed by qualified machinists familiar with carbide tooling. Ensure the machine spindle and chuck or collet are clean and free of runout before seating the straight-cylindrical shank. Power down and lock out the machine before changing tooling. Avoid applying side loads to the flute body, as solid carbide is brittle and susceptible to chipping under lateral force.
