Walter-titex 5057072 Screw Machine Drill Bit 0.213in

Product Description

The WALTER-TITEX 5057072 is a screw machine length cobalt vanadium high speed steel drill bit designed for demanding drilling applications across a range of workpiece materials. At 0.213 inches (Wire Size #3) in diameter, this bit features a 130-degree split point and parabolic flute geometry that combine to reduce walking at entry, clear chips efficiently, and extend tool life under high-cycle production conditions. The straight-cylindrical shank seats securely in standard drill chucks. With a 3xD flute-to-diameter ratio and web-thinned, tapered web construction, it delivers consistent hole quality rated for universal performance across ferrous and non-ferrous materials.

This screw machine length drill bit is suited for production drilling in metalworking shops, maintenance environments, and fabrication operations where short, rigid tooling is preferred over jobber-length bits. Primary workpiece materials include steel, stainless steel, cast iron, hard materials, and non-ferrous metals. The bright uncoated finish and cobalt vanadium HSS composition make it appropriate for both manual drill press setups and CNC short-run operations. It is sold individually and built to DIN, ISO, and BS standards, indicating dimensional and geometric conformance for interchangeable tooling programs.

Key Features

• Cobalt vanadium high speed steel construction for improved heat resistance and wear resistance in hard and abrasive materials
• 130-degree split point reduces drill walk and lowers thrust force at entry
• Parabolic flute profile promotes efficient chip evacuation, especially in deep or interrupted cuts
• Web-thinned tapered web reduces cutting resistance and improves centering
• Screw machine length (overall length 2-19/32 inches) provides added rigidity compared to jobber-length drill bits
• Right-hand cut, straight-cylindrical shank fits standard drill chucks without adapters

Compatibility

Designed for use in standard straight-shank drill chucks on drill presses, CNC machining centers, and handheld power drills. Rated for universal performance across steel, stainless steel, cast iron, hard materials, and non-ferrous metals per Series A1148 design parameters.

Installation Notes

Installation and use of this drill bit should be performed by qualified machinists or trade professionals familiar with metal cutting operations. Secure the shank fully in the chuck and confirm runout is within acceptable limits before drilling. Always power down and lock out the machine before changing tooling. Do not exceed the recommended maximum drilling depth of 0.700 inches for this bit size without retracting to clear chips.
