Walter-prototyp 7438170 Square End Mill 4 Flute Solid Carbide

Product Description

The WALTER-PROTOTYP 7438170 is a single-end square end mill designed for precise milling operations in metalworking and machining environments. Built from solid carbide, this tool delivers rigidity and wear resistance suited to demanding cutting applications. It features a 0.5-inch shank diameter and a 4-flute geometry that balances chip evacuation with surface finish quality. The TiAlN coating provides thermal and oxidation resistance, extending tool life in dry or semi-dry machining conditions. Machinists and CNC operators working in job shops, production facilities, and toolrooms are the primary users of this tooling.

This end mill is suited for milling slots, pockets, profiles, and contours in ferrous and non-ferrous materials where a square shoulder finish is required. The right-hand cutting direction and right-hand flute direction make it compatible with standard CNC machining centers and manual knee mills configured for conventional toolholding. Its single-end design is standard for precision tooling applications where tool length and runout control are critical to part quality.

Key Features

• Solid carbide construction for rigidity and long tool life in demanding cuts
• TiAlN coating resists heat and oxidation, supporting dry or semi-dry machining
• 4-flute geometry balances material removal rate with surface finish quality
• 0.5-inch shank diameter fits standard ER and side-lock toolholders
• Right-hand cut and right-hand helix for use in standard CNC and manual setups
• Single-end design for precise length control and reduced runout

Compatibility

Designed as a standard-geometry square end mill with a 0.5-inch shank for use in CNC machining centers, manual mills, and toolholding systems that accept 0.5-inch shank tooling.

Installation Notes

Installation of end mills should be performed by a qualified machinist or CNC operator. Ensure the machine spindle is fully stopped and locked out before loading or unloading tooling. Use a properly sized collet or toolholder to achieve the recommended gauge length and minimize runout. Inspect the shank and toolholder bore for chips or contamination before seating the tool.
