Value Collection 723-9201 Square End Mill 0.7874 in 2 Flute

Product Description

The VALUE COLLECTION 723-9201 is a 2-flute cobalt square end mill designed for material removal and profile milling in metalworking applications. Built from M42 cobalt high-speed steel, it delivers heat resistance and edge retention when cutting ferrous metals and high-temperature alloys. The 0.7874 inch (20 mm) cutting diameter pairs with a 1.5 inch length of cut and a 30-degree helix angle, making it well suited for slotting, side milling, and peripheral cutting operations. The bright, uncoated finish leaves the steel exposed for applications where coating buildup or heat masking is a concern. Licensed machinists and tool-and-die professionals are the typical end users.

This end mill is intended for use on CNC machining centers and manual mills in job shop, production, and maintenance environments. Its centercutting geometry allows plunge entry directly into the workpiece. The right-hand cut and right-hand flute configuration is standard for conventional spindle rotation. Primary workpiece materials include steel, stainless steel, cast iron, and high-temperature alloys, making it versatile across a wide range of industrial machining tasks. The regular-length body and 0.625 inch shank diameter fit standard ER and side-lock toolholders commonly found in most shops.

Key Features

• M42 cobalt steel construction for heat resistance and edge retention in ferrous and high-temp alloy cutting
• Centercutting design allows direct plunge milling without pre-drilling
• 30-degree helix angle promotes smooth chip evacuation in spiral flute configuration
• Bright, uncoated finish suitable for applications requiring bare-steel tool contact
• Right-hand cut and right-hand flute for standard spindle operation
• Single-end design with regular length for rigid setups and reduced deflection

Compatibility

Designed for use with standard 0.625 inch shank toolholders on CNC machining centers and manual milling machines. Compatible primary workpiece materials include steel, stainless steel, cast iron, and high-temperature alloys as specified by the manufacturer.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the machine spindle is fully stopped and locked out before changing or securing the end mill in the toolholder. The shank should be inserted to the minimum recommended engagement depth per the toolholder manufacturer's guidelines to prevent pullout under load. Verify runout with a dial indicator after mounting to confirm proper seating before beginning a cut.
