Walter-prototyp 7991096 Square End Mill 3/8 in 6 Flute

Product Description

The WALTER-PROTOTYP 7991096 is a solid carbide square end mill designed for precision milling in demanding machining environments. With a 3/8 inch cutting diameter and 6 flutes, this tool delivers high material removal rates and superior surface finishes on ferrous and non-ferrous metals. The 50-degree helix angle promotes aggressive chip evacuation and reduced cutting forces. A TiAlN coating adds thermal and oxidation resistance, extending tool life in high-speed and dry cutting applications. This end mill is installed and operated by machinists and CNC programmers working in job shops, production facilities, and toolroom environments.

This end mill is suited for slot milling, peripheral milling, and profiling operations on machining centers and CNC mills. The 1 inch length of cut accommodates moderate-depth passes, while the 3 inch overall length keeps the tool stiff and minimizes deflection. Its right-hand cutting and right-hand flute direction make it compatible with standard spindle rotation on vertical and horizontal machining centers. The single-end configuration is typical for production tooling where indexing is not required.

Key Features

• Solid carbide construction for rigidity and long tool life in hardened and abrasive materials
• 6-flute geometry increases feed rate capability and improves surface finish
• 50-degree helix angle enhances chip flow and reduces heat buildup at the cutting edge
• TiAlN coating provides oxidation resistance and supports high-speed dry or semi-dry cutting
• Right-hand cut and right-hand flute direction for standard CNC spindle compatibility
• Single-end design with 3/8 inch shank diameter for direct collet or end mill holder mounting

Compatibility

Designed as an OEM-style solid carbide square end mill for use in standard 3/8 inch collets, ER collet chucks, or end mill holders on CNC vertical and horizontal machining centers.

Installation Notes

This tool is installed by machinists using a compatible collet chuck or end mill holder sized for a 3/8 inch shank. Ensure the spindle is fully stopped and the machine is in a safe lockout state before changing tooling. Verify runout with a dial indicator after seating the tool, as excessive runout accelerates wear on carbide cutting edges. Follow the machine tool manufacturer and toolholder manufacturer guidelines for torque and clamping force when securing the tool.
