Value Collection 723-3938 Square End Mill 1-1/2 in 6 Flute

Product Description

The VALUE COLLECTION 723-3938 is a single-end square end mill designed for milling ferrous and high-strength materials in machining applications. Manufactured from M42 cobalt high-speed steel, this tool delivers heat resistance and edge retention under demanding cutting conditions. It features a 1.5-inch mill diameter, a 2-inch length of cut, and 6 spiral flutes with a 30-degree helix angle for efficient chip evacuation and smooth material removal. The bright uncoated finish is suited for applications where coating is not required or where re-sharpening is anticipated. Overall length is 4.375 inches with a 0.75-inch shank diameter.

This end mill is used in vertical and horizontal milling operations across job shops, tool rooms, and production machining environments. It is appropriate for slotting, profiling, and peripheral milling in a range of materials including alloy steels, stainless steels, and other tough workpiece materials where cobalt tooling is standard. The right-hand cutting and right-hand flute direction are compatible with conventional CNC machining center and manual mill setups. The centercutting geometry allows for direct plunge entry into the workpiece.

Key Features

• M42 cobalt high-speed steel construction for elevated heat and wear resistance
• 6 spiral flutes with 30-degree helix angle for efficient chip evacuation
• 1.5-inch mill diameter with 2-inch length of cut for deep slotting and profiling
• Centercutting design allows direct plunge milling
• Right-hand cut and right-hand flute direction for standard CNC and manual mill compatibility
• Bright uncoated finish suitable for regrinding and general-purpose applications

Compatibility

Designed as an OEM-style replacement or standard tooling option for milling machines accepting a 0.75-inch straight shank end mill in the regular length series, fractional inch sizing.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Secure the shank fully within the tool holder or collet to the recommended engagement depth per the tool holder manufacturer specifications. Verify runout with a dial indicator after installation before beginning a cut.
