Walter-titex 7377452 Solid Carbide Jobber Drill 4.80 Mm

Product Description

The WALTER-TITEX 7377452 is a solid carbide jobber drill designed for high-performance drilling in demanding trade and industrial applications. It features a 4.80 mm diameter with a 140-degree split point and a dual-layer TiSiAlCrN/AlTiN coating that extends tool life when cutting steel, cast iron, aluminum, and non-ferrous materials. The 5xD flute-to-diameter ratio and through-coolant capability make this drill well suited for deep, repeatable holes where heat and chip evacuation are critical. It is installed by machinists and tool-and-die professionals working with CNC machining centers and precision drill presses.

This drill fits standard straight-cylindrical shank toolholders with a 6 mm shank diameter. It is used in production environments for blind holes, cross holes, inclined hole exits, and stack drilling operations across steel and non-ferrous workpieces. The right-hand spiral flute geometry and 140-degree point angle work together to reduce thrust force and improve hole entry accuracy. Typical applications include aerospace component machining, automotive part production, and general metalworking where tight diameter tolerances are required. The m7 diameter tolerance ensures consistent fit across repeat production runs.

Key Features

• Solid carbide construction for rigidity and wear resistance in ferrous and non-ferrous materials
• Dual-layer TiSiAlCrN/AlTiN coating provides thermal protection and extends cutting edge life
• 140-degree point angle reduces axial thrust and improves drill entry on flat and inclined surfaces
• Through-coolant design supports deep hole drilling up to 35 mm maximum depth
• Right-hand, 2-flute regular spiral geometry optimizes chip evacuation in blind and cross-hole applications
• Straight cylindrical shank with m7 diameter tolerance for consistent toolholder fit

Compatibility

Designed for use in standard straight-shank drill chucks and precision toolholders accepting a 6 mm shank diameter. Rated for primary workpiece materials including steel, cast iron, aluminum, and non-ferrous metals per material codes K, N, P, and S. Conforms to ANSI and ISO standards. Part of the WALTER-TITEX DC160 series.

Installation Notes

Installation is performed by qualified machinists using CNC machining centers or drill presses equipped for through-coolant delivery. Ensure the spindle and coolant supply are fully shut down and locked out before inserting or removing the tool from its holder. Verify toolholder collet or chuck bore matches the 6 mm shank diameter to maintain runout tolerances. Do not exceed the rated maximum drilling depth of 35 mm without re-evaluating feeds, speeds, and coolant flow.
