Walter-titex 7377528 Jobber Drill Bit 5/16 in Solid Carbide

Product Description

The WALTER-TITEX 7377528 is a jobber length drill bit designed for high-performance drilling in demanding trade and industrial applications. Built from solid carbide with a dual-layer TiSiAlCrN/AlTiN coating, this bit delivers extended tool life and heat resistance when drilling hard or abrasive materials. It carries a 140-degree drill point angle optimized for fast chip evacuation and accurate entry. The straight-cylindrical shank measures 8.00 mm in diameter and 36.00 mm in length, making it compatible with standard drill chucks. With coolant-through capability and a 5xD flute-to-diameter ratio, this bit is built for precision work in production and maintenance environments.

This drill bit is rated for use in cast iron, non-ferrous metals, steel, superalloys, and titanium. It is well suited for blind hole drilling, cross hole drilling, inclined hole exit drilling, and stack drilling operations. The two-flute spiral configuration and 53.00 mm flute length support efficient chip removal across these applications. It is appropriate for use in CNC machining centers, drill presses, and handheld power tools where a straight shank is acceptable. Machinists, tool and die tradespeople, and maintenance technicians working with the listed materials will find this bit a practical choice.

Compatibility

Rated for primary workpiece materials including cast iron, non-ferrous metals, steel, superalloys, and titanium (material codes K, N, P, S). Part of the WALTER-TITEX Series DC160. Diameter tolerance class m7. Suitable for applications requiring blind hole, cross hole, inclined hole exit, or stack drilling with a maximum drilling depth of 43.00 mm.

Installation Notes

Installation and use should be performed by qualified machinists or tradespeople familiar with carbide tooling. Verify chuck compatibility with the 8.00 mm straight-cylindrical shank before mounting. Solid carbide bits are brittle compared to high-speed steel — avoid lateral loading, side pressure, or interrupted cuts that exceed the tool design. When using coolant-through capability, confirm the machine spindle and toolholder support internal coolant delivery at the required pressure.
