Value Collection 723-3221 Square End Mill 1 in 4 Flute Cobalt

Product Description

The VALUE COLLECTION 723-3221 is a single-end cobalt square end mill designed for milling ferrous and high-temperature alloy materials in machining center and manual mill applications. Built from M42 cobalt high-speed steel, it delivers heat resistance and edge retention under demanding cutting conditions. The 1-inch mill diameter is paired with a 2-inch length of cut, a 4.5-inch overall length, and a 30-degree helix angle that promotes efficient chip evacuation. Four spiral flutes provide a balance of strength and surface finish capability. The bright, uncoated finish makes wear monitoring straightforward during a tool life cycle.

This end mill is suited for general-purpose side milling, slotting, and profiling operations in job shop and production environments. The 1-inch shank diameter fits standard R8, CAT, BT, and other common toolholding systems. Its regular-length geometry makes it appropriate for setups where extended reach is not required. Machinists working on steel, stainless, and heat-resistant alloys will find the M42 cobalt grade well matched to those workpiece materials. It is a right-hand cut, right-hand flute tool and is centercutting, allowing plunge entry.

Key Features

• M42 cobalt high-speed steel construction for heat and wear resistance in tough alloy cutting
• Centercutting design allows direct plunge entry into workpiece material
• 30-degree helix angle promotes smooth chip flow and reduces cutting forces
• Four spiral flutes balance material removal rate with edge strength
• Bright, uncoated finish enables easy visual inspection of cutting edge wear
• Right-hand cut and right-hand flute geometry for standard spindle direction use

Compatibility

Designed as a general-purpose replacement or production end mill for standard toolholding systems accepting a 1-inch shank diameter in fractional-inch milling applications.

Installation Notes

Installation is performed by a machinist or toolroom technician. Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before changing tooling. Seat the shank fully into the collet or end mill holder and torque the retention mechanism to the toolholder manufacturer specification. Verify runout with a dial indicator before engaging the cut; excessive runout accelerates edge wear and reduces surface finish quality.
