Value Collection 723-1001 Square End Mill 1/8 in Cobalt

Product Description

The VALUE COLLECTION 723-1001 is a cobalt square end mill designed for metal removal in milling applications on ferrous and high-temperature alloy workpieces. Built from M42 cobalt high-speed steel, it delivers greater heat and wear resistance than standard HSS tooling. The cutter measures 0.125 inches in diameter with a 0.375-inch length of cut, a 0.375-inch shank diameter, and a 2.3125-inch overall length. The bright uncoated finish suits applications where coating adhesion or thermal buildup is not a primary concern. Two spiral flutes at a 30-degree helix angle provide efficient chip evacuation in the materials this tool is rated for.

This end mill is suited for milling steel, stainless steel, cast iron, and high-temperature alloys in light-duty to moderate machining operations. Its centercutting geometry allows plunge entry as well as peripheral and slot cuts. The regular-length body fits standard vertical milling machines, CNC machining centers, and manual knee mills where a 3/8-inch collet or end mill holder is available. Single-end configuration means the cutting end is one side only, keeping overall tool length compact for tight setups.

Key Features

• M42 cobalt HSS construction for improved heat resistance over standard M2 HSS tooling
• Two spiral flutes with 30-degree helix angle for efficient chip evacuation
• Centercutting design enables plunge milling without a pre-drilled pilot hole
• Right-hand cut and right-hand flute direction — compatible with standard spindle rotation
• Bright uncoated finish — no coating concerns for re-sharpening or reactive workpiece materials
• Regular-length series for general-purpose reach in most fixturing setups

Compatibility

Rated for use in steel, stainless steel, cast iron, and high-temperature alloys. Fits any spindle or tool holder accepting a 0.375-inch straight shank.

Installation Notes

Installation is performed by a machinist or toolroom technician using a collet chuck or end mill holder sized to the 0.375-inch shank. Ensure the spindle is fully stopped and the machine is powered down or in E-stop before changing tooling. Secure the shank to the full recommended grip depth in the holder to minimize runout and tool pullout risk. Verify shank engagement and holder torque per the machine tool manufacturer specifications before beginning a cut.
