Walter-titex 5057207 Screw Machine Drill Bit 0.2244 in

Product Description

The WALTER-TITEX 5057207 is a screw machine length drill bit designed for high-performance drilling in demanding materials. Built from cobalt vanadium high speed steel with a bright uncoated finish, this bit delivers consistent performance in cast iron, stainless steel, hard materials, non-ferrous metals, and steel. The 0.2244-inch diameter and 130-degree split point keep the bit on center at entry and reduce thrust in tough workpieces. The parabolic flute geometry promotes efficient chip evacuation, making it well suited for production and maintenance drilling environments where cycle time and hole quality matter.

This bit is sized for screw machine length applications, offering a compact overall length of 2-19/32 inches with a maximum drilling depth of 0.700 inches. The straight-cylindrical shank fits standard drill chucks without adapters. Web thinning with a tapered web configuration reduces cutting resistance at the tip. It is intended for machinists, tool-and-die technicians, maintenance mechanics, and fabricators working with stainless steel, hard alloys, and cast iron in both production and job-shop settings. The universal tool performance rating means it handles a broad range of materials without specialized setup.

Key Features

• Cobalt vanadium high speed steel construction for heat resistance in hard and abrasive materials
• 130-degree split point for self-centering entry and reduced walking on hard surfaces
• Parabolic flute profile with 3xD flute-to-diameter ratio for fast, clean chip removal
• Web-thinned tapered web reduces cutting force and extends tool life
• Straight-cylindrical shank fits standard chucks without adapters or sleeves
• Meets DIN, ISO, and BS standards; rated high performance grade

Compatibility

Designed as a screw machine length drill bit suitable for use in drill presses, CNC machining centers, lathes, and hand-held drill motors accepting straight-cylindrical shank tooling. Primary workpiece materials include cast iron, hard material, non-ferrous metal, stainless steel, and steel per Series A1148 specifications.

Installation Notes

Installation and use should be performed by qualified machinists or tooling technicians familiar with drill bit selection, speed, and feed requirements for the target workpiece material. Secure the straight-cylindrical shank fully in the chuck and verify runout before drilling. Ensure the workpiece is clamped securely to prevent movement during the cut. This bit does not support coolant-through delivery; apply cutting fluid externally as appropriate for the workpiece material.
