Guhring 9055140061000 Carbide Screw Machine Drill Bit

Product Description

The GUHRING 9055140061000 is a solid carbide screw machine length drill bit designed for high-performance drilling in demanding shop and production environments. Built to DIN 6537 K standards, this bit features a 140-degree split point with web thinning for fast, accurate starts and reduced thrust. The straight-cylindrical shank and 2-flute spiral configuration promote efficient chip evacuation and consistent hole quality. At 0.2402 inches in diameter with an overall length of 2.5984 inches, this bit is sized for precision work in ferrous and cast iron applications. Licensed machinists, tool-and-die technicians, and production drill press operators are the primary users.

This drill bit is well suited for production drilling in cast iron and steel workpieces where tight tolerances and repeatable performance are required. Its screw machine length profile makes it appropriate for use in CNC machining centers, drill presses, and automatic screw machines where shorter flute lengths improve rigidity and reduce deflection. The coated finish extends tool life in high-cycle production runs. Maximum drilling depth is 0.9780 inches, making it practical for through-hole and shallow blind-hole operations in ferrous stock.

Key Features

• Solid carbide construction with submicron carbide grade for hardness and wear resistance
• 140-degree SU point with web thinning reduces walking and improves penetration in hard materials
• Coated finish extends cutting life in steel and cast iron applications
• Right-hand cut, 2-flute spiral design promotes efficient chip evacuation
• Screw machine length profile improves rigidity and reduces deflection in production setups
• Compliant with DIN 6537 K specification for consistent dimensional accuracy

Compatibility

Designed as an OEM-style replacement or direct production drill bit for applications requiring a 0.2402-inch diameter solid carbide screw machine drill compliant with DIN 6537 K standards, suitable for cast iron and steel workpieces.

Installation Notes

Installation should be performed by qualified machinists or tool technicians familiar with carbide tooling. Ensure the spindle and chuck or collet are clean and within manufacturer runout tolerances before seating the straight-cylindrical shank, as carbide bits are sensitive to side-loading and runout. Power down and de-energize the machine before changing tooling. Do not use carbide bits in hand drills or flex-shaft tools where vibration and runout cannot be controlled.
