Value Collection 723-8634 Square End Mill 7mm 4 Flute Cobalt

Product Description

The VALUE COLLECTION 723-8634 is a cobalt square end mill designed for metal cutting operations in machine shop and production environments. Built from M42 cobalt high-speed steel, it delivers improved heat and wear resistance compared to standard HSS tooling, making it suitable for harder materials and higher cutting speeds. The 7 mm (0.2756 inch) cutting diameter pairs with a 4-flute spiral geometry and a 30-degree helix angle to balance chip evacuation with surface finish quality. This is a single-end, right-hand cut tool with a bright/uncoated finish, appropriate for use in vertical mills, CNC machining centers, and manual knee mills.

This end mill is suited for general-purpose milling of ferrous and non-ferrous metals, including alloy steels, tool steels, and cast iron, where cobalt tooling is preferred over standard HSS. The regular-length configuration and 3/8 inch shank diameter make it compatible with standard ER and end mill holders. It is center-cutting, allowing plunge entry in addition to conventional peripheral and slot milling. Machinists and tool-and-die professionals will find it appropriate for profiling, slotting, and light contouring work.

Key Features

• M42 cobalt construction for improved heat resistance and longer tool life in harder materials
• 4 spiral flutes with 30-degree helix angle for efficient chip removal and smooth cutting action
• Center-cutting geometry allows direct plunge entry without a pre-drilled pilot hole
• Right-hand cut and right-hand flute direction for use in standard spindle rotation setups
• Bright/uncoated finish suitable for use with or without cutting fluid
• Single-end design; regular length series VCCC-C-4

Compatibility

Designed as a general-purpose replacement or production end mill for standard 3/8 inch end mill holders and ER collet chucks used in vertical milling machines and CNC machining centers.

Installation Notes

Installation should be performed by a qualified machinist following shop safety procedures. Ensure the machine spindle is fully stopped and locked out before inserting or removing the tool. Seat the shank to the minimum recommended engagement depth in the holder and torque the set screw or collet nut per the holder manufacturer specifications. Verify runout with a dial indicator before beginning a cut, particularly for tight-tolerance work.
