Guhring 9055140075000 Carbide Drill Bit 0.2953 in 140 Deg

Product Description

The GUHRING 9055140075000 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, it features a 0.2953-inch diameter, a 140-degree split point (SU type), and a web-thinned, parallel web construction that reduces entry force and improves chip evacuation. The two-flute spiral design and right-hand cut deliver consistent, accurate holes in demanding production environments. Licensed HVAC, plumbing, and mechanical contractors as well as industrial machinists reach for this bit when working with ferrous metals that require tight tolerances and clean bore geometry.

This drill bit is suited for screw machine and production drilling applications in cast iron and steel workpieces. The straight-cylindrical shank with an 8 mm shank diameter fits standard drill chucks and collet holders used on CNC machining centers, drill presses, and screw machines. The 3xD flute-to-diameter ratio and 41 mm flute length support chip clearance in moderate-depth holes. It is packaged as a single unit and is appropriate wherever a compact, stubby-length carbide drill is required for precision metal removal.

Key Features

• Solid carbide construction with submicron material grade for extended tool life in ferrous metals
• 140-degree SU split point reduces walking and lowers thrust force on entry
• Web-thinned parallel web geometry improves chip flow and reduces heat buildup
• Coated finish for added wear resistance and surface protection
• Right-hand spiral flute, screw machine length for rigid, low-deflection drilling
• Meets DIN 6537 K specification for consistent dimensional accuracy

Compatibility

Designed for use in cast iron and steel workpieces. Fits standard drill chucks and collet holders accepting an 8 mm straight-cylindrical shank. Belongs to GUHRING Series 5514.

Installation Notes

Installation and use should be performed by qualified machinists or trade professionals familiar with carbide tooling. Secure the shank fully in a properly sized collet or drill chuck before operation, and verify spindle speed and feed rate are appropriate for the workpiece material and drill diameter. Carbide tooling is brittle and can fracture if subjected to lateral load or impact — avoid hand-feeding with excessive force. Inspect the cutting edges for chipping before each use and replace if damaged.
