Walter-titex 5057073 Screw Machine Drill Bit 0.1285 in

Product Description

The WALTER-TITEX 5057073 is a screw machine length drill bit engineered for high-performance drilling in demanding trade and industrial applications. Built from Cobalt Vanadium High Speed Steel with a bright, uncoated finish, it carries a 0.1285-inch diameter (Wire Size #30) and an overall length of 1-15/16 inches. The 130-degree split point reduces walking and thrust, while the parabolic flute geometry improves chip evacuation and reduces heat buildup. With a maximum drilling depth of 0.500 inches and a tapered web configuration, this bit is suited for production drilling environments where tool life and hole quality matter. It is manufactured to DIN and ISO standards at a high-performance grade.

This drill bit is designed for use on cast iron, steel, stainless steel, hard materials, and non-ferrous metals, making it a versatile choice across fabrication, maintenance, and repair operations. The screw machine length profile - shorter than jobber length - provides added rigidity when drilling in drill presses, CNC machining centers, or screw machine setups where spindle clearance is limited. The straight-cylindrical shank fits standard drill chucks without modification. Machinists, millwrights, and industrial maintenance technicians commonly reach for this bit when working with tight-tolerance hole requirements in hard or abrasive materials.

Key Features

• Cobalt Vanadium High Speed Steel construction for extended tool life in hard and abrasive materials
• 130-degree split point reduces drill walk and lowers required thrust force
• Parabolic flute geometry promotes efficient chip removal and reduces heat in the cut zone
• Screw machine length body adds rigidity over jobber-length alternatives in close-clearance setups
• Web-thinned, tapered web design balances strength with cutting efficiency
• Meets DIN, ISO, and BS specification designations for dimensional consistency

Compatibility

Designed as an OEM-style replacement or direct-use drill bit for applications requiring a 0.1285-inch (Wire Size #30) screw machine length bit in standard drill chucks or machining center collets. Compatible workpiece materials include cast iron, steel, stainless steel, hard materials, and non-ferrous metals per Series A1148 design parameters.

Installation Notes

Installation and use should be performed by qualified machinists or maintenance technicians familiar with rotating cutting tools and applicable shop safety practices. Secure the straight-cylindrical shank fully in the chuck before operation and verify chuck key removal prior to spindle startup. Do not exceed the recommended maximum drilling depth of 0.500 inches in a single pass without retracting to clear chips. Cutting fluid or coolant is recommended when drilling stainless steel or hard materials, even though this bit does not have internal coolant-through capability.
