Walter-titex 7377481 Carbide Jobber Drill 6mm DC160

Product Description

The WALTER-TITEX 7377481 is a solid carbide jobber-length drill bit engineered for high-performance drilling in demanding production environments. Sized at 6.00 mm (0.2362 inches) in diameter with a 140-degree split point, it cuts aggressively while reducing thrust and walking on entry. A dual-layer proprietary coating -- TiSiAlCrN over an AlTiN base -- delivers thermal resistance and wear protection for extended tool life in abrasive and hard materials. Overall length is 82.00 mm (3.2283 inches) with a 44.00 mm (1.7323-inch) flute length. The shank diameter is 6 mm with a straight-cylindrical profile, making it compatible with standard drill chucks and collet toolholders. This bit is suitable for machinists and tool-and-die professionals working in high-volume or precision drilling applications.

The 7377481 is rated for use in steel, cast iron, aluminum, and non-ferrous materials -- material codes P, K, N, and S. It supports blind hole drilling, cross holes, inclined hole exits, and stack drilling. The 5xD flute-to-diameter ratio and through-coolant capability make it well suited for deeper cuts and higher feed rates where chip evacuation and heat management are critical. It is appropriate for CNC machining centers, drill presses, and automated drilling operations where dimensional accuracy and consistent hole quality are required. Maximum drilling depth is 35.00 mm (1.378 inches).

Key Features

• Solid carbide construction with material grade WJ30ET for high rigidity and wear resistance
• Dual-layer TiSiAlCrN / AlTiN coating for thermal stability and extended tool life
• 140-degree point angle reduces thrust and minimizes drill walk on entry
• Through-coolant capable for improved chip evacuation and heat control in deep holes
• Supports blind holes, cross holes, inclined exits, and stack drilling
• Diameter tolerance to m7 for consistent, accurate hole sizing

Compatibility

Designed for use in steel, cast iron, aluminum, and non-ferrous workpiece materials (material codes P, K, N, and S). Part of the WALTER-TITEX DC160 series of high-performance carbide jobber drills. Conforms to ANSI and ISO standards. Fits standard 6 mm straight-shank chucks and collet systems.

Installation Notes

Installation and use should be performed by qualified machinists or CNC operators familiar with carbide tooling setup and feeds-and-speeds selection. Ensure the spindle, chuck, or collet is clean and properly torqued before use, and verify runout is within acceptable limits to prevent premature carbide breakage. Activate through-coolant supply before drilling when available to protect coating integrity and extend tool life. Carbide tooling is brittle -- avoid impact loads, interrupted cuts without appropriate parameters, and re-using drills with visible edge chipping.
