Walter-titex 5057125 Screw Machine Drill Bit 0.4016 in

Product Description

The WALTER-TITEX 5057125 is a screw machine length drill bit designed for high-performance drilling in demanding industrial applications. Built from Cobalt Vanadium High Speed Steel with a bright, uncoated finish, it measures 0.4016 inches in diameter and 3.5 inches in overall length. The 130-degree split point and parabolic flute geometry work together to reduce walking on entry, improve chip evacuation, and maintain cutting efficiency through hard and abrasive materials. The straight-cylindrical shank ensures positive grip in standard drill chucks and quick-change holders. Licensed machinists, tool-and-die workers, and maintenance professionals handling tough materials rely on this bit for repeatable, accurate results.

This drill bit is suited for drilling cast iron, stainless steel, hardened steel, non-ferrous metals, and other hard materials in production and maintenance environments. The screw machine length format provides a rigid, short-body profile that reduces deflection in CNC machining centers, drill presses, and manual machine tools. The web-thinned, tapered web configuration minimizes thrust force at the cutting tip. The A1148 series is built to DIN, ISO, and BS standards, making it appropriate for shops working to international tooling specifications.

Key Features

• Cobalt Vanadium High Speed Steel construction for heat and wear resistance in hard materials
• 130-degree split point reduces entry thrust and eliminates center punching on most materials
• Parabolic flute design accelerates chip removal and reduces re-cutting
• Web-thinned, tapered web lowers axial cutting force
• Straight-cylindrical shank fits standard drill chucks and quick-change systems
• Meets DIN, ISO, and BS standards for dimensional consistency

Compatibility

Designed for use with standard drill chucks and quick-change toolholders accepting straight-cylindrical shanks in the 0.4016-inch diameter range. Suitable for CNC machining centers, drill presses, and manual machine tools working in the WALTER-TITEX A1148 series application range, including cast iron, stainless steel, steel, hard materials, and non-ferrous metals.

Installation Notes

Installation and use should be performed by qualified machinists or tool operators familiar with cutting tool setup and machine tool operation. Secure the shank fully in the chuck before operation and verify runout before committing to production cuts. Cutting speeds and feeds should be selected based on workpiece material and machine rigidity; consult the WALTER-TITEX cutting data recommendations for the A1148 series. Inspect the cutting edges before each use and replace the bit at first sign of chipping or excessive wear to prevent workpiece damage.
