Walter-titex 5057127 Screw Machine Drill Bit 0.4252 in

Product Description

The WALTER-TITEX 5057127 is a screw machine length drill bit designed for high-performance drilling in demanding industrial and trade applications. Built from cobalt vanadium high speed steel, it delivers the hardness and heat resistance required when cutting through stainless steel, cast iron, hard materials, and non-ferrous metals. The bit measures 0.4252 inches in diameter with an overall length of 3.75 inches and a flute length of 1.84 inches. A 130-degree split point reduces walking and lowers entry force, while the parabolic flute geometry improves chip evacuation at depth. Licensed machinists, tool-and-die professionals, and industrial maintenance technicians are the primary installers of this type of bit.

The 5057127 is suited for screw machine operations and general-purpose drilling where a compact stub-length bit is preferred over jobber or taper length. The 3xD flute-to-diameter ratio and web-thinned, tapered web design allow efficient drilling to a maximum depth of 1.100 inches. It performs across a wide range of workpiece materials including steel, stainless steel, cast iron, hard materials, and non-ferrous metals, making it a reliable choice for production environments and maintenance shops alike. The straight cylindrical shank seats in standard drill chucks without modification.

Compatibility

Designed for use across primary workpiece materials including steel, stainless steel, cast iron, hard materials, and non-ferrous metals. Part of the WALTER-TITEX Series A1148 screw machine drill bit family, covering the 0.4000 to 0.4500 inch diameter size range.

Installation Notes

Install in a standard drill press, CNC machining center, or hand drill with a chuck rated for straight cylindrical shanks. Secure the shank fully in the chuck and verify runout before beginning a cut. De-energize and lock out all rotating equipment before changing tooling per applicable machine safety standards. Do not exceed the manufacturer-rated maximum drilling depth of 1.100 inches per pass without retracting to clear chips.
