Walter-titex 5153735 Screw Machine Drill Bit 0.377in

Product Description

The WALTER-TITEX 5153735 is a screw machine length drill bit designed for high-performance drilling in demanding materials including steel, stainless steel, cast iron, hard materials, and non-ferrous metals. Built from cobalt and vanadium high speed steel, this bit delivers the heat and wear resistance required for tough workpiece materials. It measures 0.377 inches in diameter (Letter V) with an overall length of 3.5 inches and a flute length of 1.6875 inches. The 130-degree split point and parabolic flute geometry reduce walking on entry and improve chip evacuation, making it well suited for production drilling and repair work across multiple material types.

This drill bit is configured for screw machine length applications where a compact, rigid profile is preferred over jobber or taper length options. The straight-cylindrical shank seats securely in standard drill chucks and machine spindles. Its universal tool performance rating and 3xD flute-to-diameter ratio make it appropriate for CNC machining centers, drill presses, and handheld power tools used in metal fabrication, maintenance, and industrial service settings. A maximum drilling depth of 1.1 inches suits typical through-hole and blind-hole operations in the materials listed.

Key Features

• Cobalt and vanadium high speed steel construction for extended tool life in hard and abrasive materials
• 130-degree split point reduces thrust and prevents bit walking on entry
• Parabolic flute geometry improves chip evacuation and reduces heat buildup
• Web-thinned, tapered web configuration lowers cutting resistance
• Bright/uncoated finish suitable for use with cutting fluids across varied materials
• Meets DIN, ISO, and BS standards for dimensional consistency and interchangeability

Compatibility

Designed as an OEM-style replacement or direct-use drill bit for screw machine length applications in Series A1148. Compatible with standard straight-shank drill chucks and machine spindles accepting a 0.377-inch shank. Rated for use in cast iron, hard materials, non-ferrous metals, stainless steel, and steel workpieces.

Installation Notes

Installation and use of this drill bit is performed by machinists, tooling technicians, and trade professionals operating drill presses, CNC machining centers, or handheld power tools. Secure the straight-cylindrical shank fully in the chuck before operation and verify concentricity to prevent premature wear. Power down and de-energize all equipment before changing bits or adjusting tooling. Use appropriate cutting fluid for the workpiece material to extend tool life and maintain dimensional accuracy.
