Walter-titex 5057177 Screw Machine Drill Bit 0.126in

Product Description

The WALTER-TITEX 5057177 is a screw machine length drill bit engineered for high-performance drilling across a broad range of materials. It measures 0.126 inches in diameter with an overall length of 1-15/16 inches and features a 130-degree split point for accurate self-centering without a center punch. Constructed from cobalt vanadium high speed steel, this bit delivers the heat and wear resistance required for demanding production and maintenance drilling environments. The bright uncoated finish and parabolic flute geometry promote efficient chip evacuation and reduced cutting resistance. Licensed HVAC, mechanical, and industrial maintenance technicians rely on this type of bit for precision pilot and through-hole work in fabrication and equipment service.

This bit is suited for drilling cast iron, stainless steel, carbon steel, hard materials, and non-ferrous metals in both production and field maintenance contexts. The screw machine length format provides added rigidity compared to jobber-length bits, making it well suited for drill press and CNC machine tool applications where short, stiff tooling reduces deflection. The straight cylindrical shank fits standard drill chucks. Maximum drilling depth is 0.500 inches, with a flute length of approximately 0.709 inches (18.00 mm).

Key Features

• Cobalt vanadium high speed steel construction for elevated heat and wear resistance
• 130-degree split point reduces thrust and enables accurate entry without center punching
• Parabolic flute geometry promotes fast, clean chip evacuation in deep cuts
• Web-thinned, tapered web configuration reduces cutting forces at the point
• Screw machine length provides superior rigidity and reduced deflection versus jobber bits
• Meets DIN, ISO, BS, and DIN specification designations for precision tooling compliance

Compatibility

Designed as a screw machine length replacement drill bit for use in standard straight-shank drill chucks on drill presses, CNC machining centers, and hand-held drilling equipment requiring 0.126-inch diameter tooling in Series A1148.

Installation Notes

This bit is typically installed and operated by machinists, tool and die technicians, or industrial maintenance professionals. Secure the straight cylindrical shank fully in the drill chuck and verify concentricity before use. Always wear appropriate eye protection and ensure the workpiece is firmly clamped before initiating a cut. Do not exceed the recommended drilling depth of 0.500 inches per pass without retracting the bit to clear chips.
