Guhring 9055140105000 Carbide Screw Machine Drill Bit

Product Description

The GUHRING 9055140105000 is a solid carbide screw machine length drill bit designed for high-performance drilling in demanding industrial and machining applications. Built to DIN 6537 K standards, this bit features a 140-degree split point (SU type) with web thinning for reduced thrust and improved centering. The 2-flute spiral configuration with a 3xD flute-to-diameter ratio handles chip evacuation efficiently. At 0.4134 inches in diameter with a straight-cylindrical shank, it is suited for use in CNC machining centers, drill presses, and production screw machine setups where consistent, repeatable hole quality is required.

This drill bit is engineered for right-hand cutting in cast iron and steel workpieces. The screw machine length body keeps the tool compact for rigid, close-tolerance setups typical in production environments. A coated finish extends tool life by reducing friction and heat buildup during extended run cycles. Machinists and tool-and-die professionals working in high-volume drilling operations will find the submicron carbide grade and parallel web configuration well-suited for maintaining dimensional accuracy across repeated cycles.

Key Features

• Solid submicron carbide construction for high rigidity and wear resistance
• 140-degree SU split point with web thinning reduces entry thrust and improves hole location
• Coated finish extends tool life in cast iron and steel applications
• Screw machine length for compact, rigid setups in CNC and production drilling
• Straight-cylindrical shank with 12 mm shank diameter for standard collet and chuck compatibility
• Meets DIN 6537 K specification for consistent dimensional tolerances

Compatibility

Designed for use in cast iron and steel workpieces. Fits standard straight-shank tool holders and collet chucks accepting a 12 mm shank. Applicable across CNC machining centers, turret lathes, and drill presses configured for screw machine length tooling.

Installation Notes

Installation should be performed by a qualified machinist following standard tool-holding procedures for straight-shank carbide drills. Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before changing tooling. Set runout within machine and chuck specifications before operation, as carbide tooling is sensitive to deflection and misalignment. Do not use in applications outside the stated primary workpiece materials without verifying suitability.
