Walter-titex 5057132 Screw Machine Drill Bit 0.3438 in

Product Description

The WALTER-TITEX 5057132 is a screw machine length drill bit designed for high-performance drilling in demanding shop and field applications. Built from cobalt and vanadium high speed steel with a bright, uncoated finish, it measures 0.3438 inches (11/32 inches) in diameter with an overall length of 3-5/16 inches and a flute length of 1-9/16 inches. The 130-degree split point reduces walking on entry and cuts through tough workpiece materials without a center punch. A parabolic flute geometry promotes efficient chip evacuation and helps maintain cutting speed in deep-hole applications. This bit is suited for machinists, maintenance technicians, and fabricators working in production or repair environments.

The 5057132 is engineered for universal application across a broad range of workpiece materials including steel, stainless steel, cast iron, hard materials, and non-ferrous metals. Its screw machine length keeps the bit rigid and reduces deflection compared to jobber-length bits, making it a common choice for drill press work, CNC machine setups, and hand-held operations where hole location accuracy is critical. The straight cylindrical shank seats securely in standard three-jaw chucks and collet holders. Conformance to DIN, ISO, and BS standards makes it suitable for use across domestic and international manufacturing specifications.

Key Features

• Cobalt and vanadium high speed steel construction for extended tool life in hard and abrasive materials
• 130-degree split point reduces entry force and eliminates the need for center-punching on most surfaces
• Parabolic flute geometry with a 3xD flute-to-diameter ratio for fast, clean chip removal
• Web-thinned, tapered web configuration reduces thrust and improves drilling efficiency
• Screw machine length provides greater rigidity and tighter hole tolerances versus jobber-length bits
• Meets DIN, ISO, and BS standards for dimensional and performance consistency

Compatibility

Designed as an OEM-style replacement or direct-use drill bit for standard three-jaw chucks and collet holders accepting a straight cylindrical shank. Compatible with workpiece materials including steel, stainless steel, cast iron, hard materials, and non-ferrous metals per Series A1148 application specifications.

Installation Notes

This bit is installed by qualified machinists or maintenance technicians using standard drill press, CNC, or hand-held drilling equipment. Secure the straight cylindrical shank fully in the chuck or collet before operation to prevent slippage and maintain runout tolerances. Ensure the workpiece is properly fixtured and the machine spindle speed is set to a rate appropriate for the workpiece material and bit diameter. No coolant-through capability is present on this bit; external coolant or cutting fluid application is recommended when drilling stainless steel or other hard materials.
