Walter-titex 5153743 Screw Machine Drill Bit 0.6562 in

Product Description

The WALTER-TITEX 5153743 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, this bit delivers durability and heat resistance when cutting through tough workpiece materials. The 0.6562 inch (21/32 inch) diameter bit features a 130-degree split point, a parabolic flute geometry, and a web-thinned, tapered web configuration that together reduce thrust and improve chip evacuation. It is sized at 4-11/16 inches overall length and suits shop machinists, maintenance technicians, and fabricators working with high-performance tooling setups.

This bit is designed for use in screw machine length drilling operations across a broad range of base materials including steel, stainless steel, cast iron, hard materials, and non-ferrous metals. The parabolic flute and 3xD flute-to-diameter ratio make it well suited for applications requiring consistent chip removal at moderate drilling depths. Typical install scenarios include CNC drilling, manual drill press work, and turret lathe operations in production shops or maintenance facilities where precision hole tolerances and tool longevity are priorities.

Key Features

• Cobalt vanadium high speed steel construction for elevated heat resistance and extended tool life in hard materials
• 130-degree split point reduces walking and lowers entry thrust on hard and abrasion-resistant workpieces
• Parabolic flute geometry promotes fast, clean chip evacuation and reduces clogging at depth
• Web-thinned tapered web improves cutting efficiency and reduces feed force requirements
• Straight-cylindrical shank provides broad compatibility with standard drill chucks and collet holders
• Conforms to DIN, ISO, and BS standards for dimensional consistency and interchangeability

Compatibility

Designed as a Series A1148 screw machine length drill bit suited for steel, stainless steel, cast iron, hard materials, and non-ferrous metal workpieces. Compatible with standard straight-shank drill chucks and collet systems accepting a 0.6562 inch diameter shank.

Installation Notes

Installation and use should be performed by qualified machinists or maintenance technicians familiar with rotating cutting tool safety. Secure the workpiece and verify chuck or collet grip before operation. Always power down and de-energize the machine before changing tooling. Do not exceed the maximum drilling depth of 1.7000 inches in a single pass without adequate chip clearing.
