Walter-titex 7377844 Taper Length Drill Bit 5 Mm Carbide

Product Description

The WALTER-TITEX 7377844 is a solid carbide taper length drill bit engineered for high-performance drilling in demanding industrial and machining applications. Built to DIN 6537 K standards, this 5 mm diameter bit features a 140-degree point angle and a TiSiAlCrN coating that extends tool life under elevated cutting temperatures. The spiral flute geometry and right-hand cut configuration promote efficient chip evacuation. Coolant-through capability supports deep-hole and high-speed operations where heat management is critical. This bit is installed by machinists and tool-and-die professionals working on CNC and manual drill press setups.

The 7377844 is suited for a range of drilling strategies including blind hole, cross hole, inclined hole, stack drilling, and through hole drilling. Its 8xD flute-length-to-diameter ratio supports drilling depths up to 48 mm, making it appropriate for medium-deep hole work in steel, hardened materials, and alloys where carbide tooling is required. The parallel shank with a 6 mm shank diameter seats securely in standard collets and chucks.

Key Features

• Solid carbide construction rated to material grade WJ30ET for hardened and difficult-to-machine materials
• TiSiAlCrN coating reduces wear and improves performance at elevated cutting speeds
• 140-degree point angle minimizes walking and reduces thrust force at entry
• Coolant-through design delivers cutting fluid directly to the tip for deep-hole operations
• 8xD flute ratio supports maximum drilling depth of 48 mm
• Conforms to DIN 6537 K standard for consistent dimensional accuracy

Compatibility

Designed as a direct-fit replacement or standard tooling selection for setups requiring a 5 mm diameter, parallel shank, solid carbide drill bit conforming to DIN 6537 K. Compatible with collets and drill chucks accepting a 6 mm shank diameter.

Installation Notes

Installation is performed by qualified machinists. Ensure the machine spindle is fully stopped and the tool holder is clean and free of debris before seating the shank. Verify collet or chuck runout is within tolerance before operation, as carbide tooling is sensitive to lateral loading. Activate coolant-through supply prior to initiating the cut when drilling blind or deep holes.
