Guhring 9055140080000 Carbide Screw Machine Drill Bit

Product Description

The GUHRING 9055140080000 is a solid carbide screw machine length drill bit designed for high-performance drilling in cast iron and steel. Built to DIN 6537 K standards, this right-hand cut bit features a 140-degree split point (SU type) with web thinning for reduced thrust and improved chip evacuation. The two-flute spiral design and coated finish deliver consistent cutting performance in demanding production environments. With an overall length of 79 millimeters and a 0.315-inch diameter, it fits standard straight-cylindrical toolholding systems. Licensed machinists, tool-and-die shops, and maintenance mechanics rely on this bit for precision hole-making in ferrous materials.

The 9055140080000 belongs to GUHRING Series 5514 and is engineered for screw machine and short-hole drilling applications. It is well suited to CNC machining centers, drill presses, and manual machines where rigidity and runout control are critical. The 3xD flute-to-diameter ratio and parallel web configuration make it appropriate for through-hole and blind-hole work in cast iron and steel workpieces in both job-shop and production-line settings.

Key Features

• Solid submicron carbide construction for extended tool life in ferrous materials
• 140-degree SU point with web thinning reduces entry thrust and minimizes walking
• Coated finish improves wear resistance and heat dissipation
• DIN 6537 K specification ensures dimensional consistency and interchangeability
• Straight-cylindrical shank fits standard collets and drill chucks without adapters
• 3xD flute ratio optimizes chip clearance in screw machine length drilling

Compatibility

Designed as a DIN 6537 K compliant replacement for screw machine length carbide drill bits in the 0.300 to 0.350 inch diameter range, compatible with any toolholder accepting an 8 millimeter straight-cylindrical shank.

Installation Notes

Installation and use should be performed by qualified machinists or toolroom personnel familiar with carbide tooling. Ensure the spindle and toolholder are clean and within runout tolerance before seating the shank, as carbide is brittle and sensitive to lateral shock loads. Power down and lock out the machine before changing tooling. Do not use this bit for interrupted cuts or in materials outside its rated primary workpiece categories without verifying application suitability.
