Walter-titex 7377471 Solid Carbide Jobber Drill 7/32 in

Product Description

The WALTER-TITEX 7377471 is a solid carbide jobber-length twist drill engineered for high-performance drilling in ferrous and non-ferrous materials. It carries a dual-layer AlTiN/TiSiAlCrN coating that extends tool life under elevated cutting temperatures. The 140-degree split-point geometry reduces thrust force and improves self-centering on entry. At 7/32 inches (0.2188 inches) in diameter with a 3.2283-inch overall length, this drill fits standard machining setups and is installed by machinists, tool-and-die technicians, and precision metalworking professionals working on production or maintenance operations.

The 7377471 is rated for steel, cast iron, aluminum, and non-ferrous alloys, making it suitable for general machining, fabrication, and maintenance applications. Its 5xD flute-to-diameter ratio and coolant-through design support deep-hole drilling with effective chip evacuation. Approved tool applications include blind holes, cross holes, inclined-hole exits, and stack drilling. The straight cylindrical shank seats directly in standard drill chucks or collet holders without modification.

Key Features

• Solid carbide construction in material grade WJ30ET for rigidity and wear resistance
• Dual-layer AlTiN/TiSiAlCrN coating for heat resistance and extended tool life in steel and cast iron
• 140-degree point angle for reduced entry thrust and accurate self-centering
• Coolant-through design supports chip evacuation in blind-hole and deep-hole applications
• Right-hand cut, regular spiral flute with 5xD ratio and 44.00 mm flute length
• Meets ANSI and ISO standards; diameter tolerance held to m7

Compatibility

Designed as part of the Walter-Titex DC160 series for high-performance drilling in steel (P), cast iron (K), aluminum and non-ferrous materials (N), and special alloys (S) across CNC machining centers and drill presses equipped with coolant-through capability.

Installation Notes

Installation and tool changes must be performed with the machine powered down and the spindle fully stopped. Secure the straight cylindrical shank in a properly sized collet or drill chuck, verifying runout before beginning a cut. Coolant-through setups should confirm pressure and flow rate are compatible with the machine spindle before use. Follow shop-specific speeds and feeds for the workpiece material; do not exceed the 35.00 mm maximum drilling depth rating.
