Walter-titex 5057124 Screw Machine Drill Bit 0.3937 in

Product Description

The WALTER-TITEX 5057124 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 (HSS-Co), this bit delivers extended tool life when cutting through tough workpiece materials. It measures 0.3937 inches in diameter with an overall length of 3.5 inches and a flute length of 1.6875 inches. The 130-degree split point reduces walking and thrust load at entry, while the parabolic flute geometry promotes efficient chip evacuation. The straight-cylindrical shank is compatible with standard drill chucks. Machinists, tool-and-die techs, and industrial maintenance professionals rely on this bit for production drilling environments.

This bit is suited for drilling cast iron, stainless steel, hard materials, non-ferrous metals, and general steel in screw machine and production drilling setups. Its screw machine (stub) length provides added rigidity compared to jobber-length bits, making it a preferred choice for short-hole drilling where runout and deflection must be minimized. The 3xD flute-to-diameter ratio supports a maximum drilling depth of 1.1 inches. It is appropriate for both manual drill press work and CNC machining centers where shorter, stiffer tooling is required.

Key Features

• Cobalt Vanadium HSS construction provides heat and wear resistance for high-productivity drilling
• 130-degree split point reduces entry thrust and minimizes bit walking on hard materials
• Parabolic flute geometry enhances chip evacuation and reduces heat buildup in the cut
• Web-thinned tapered web design improves cutting efficiency and lowers feed force requirements
• Screw machine (stub) length adds rigidity and reduces deflection in short-hole applications
• Bright/uncoated finish; compatible with cutting fluids without adhesion concerns
• Meets DIN, ISO, and BS standards; Series A1148 classification

Compatibility

Designed for drilling cast iron, hard materials, non-ferrous metals, stainless steel, and carbon steel. The straight-cylindrical shank fits standard keyed and keyless drill chucks. Suitable for use across screw machine operations, drill presses, and CNC machining centers that accept stub-length tooling in the 0.3500 to 0.4000 inch diameter range.

Installation Notes

Installation and use should be performed by qualified machinists or maintenance professionals familiar with rotating cutting tool safety. Always secure the shank fully in the chuck and verify concentricity before running the spindle. Power down and de-energize the machine before changing tooling. Use appropriate cutting fluid or coolant for the workpiece material to maximize tool life, noting that this bit does not support coolant-through delivery.
