Value Collection 723-1142 Square End Mill 1-5/8 in 2 Flute

Product Description

The VALUE COLLECTION 723-1142 is a cobalt square end mill designed for material removal in ferrous and high-temperature alloy machining applications. Built from M42 cobalt high-speed steel, this single-end mill features a 1.625-inch cutting diameter, a 1.625-inch length of cut, and a 30-degree helix angle that promotes efficient chip evacuation and stable cutting action. The bright, uncoated finish is suited for applications where coolant or cutting fluid is applied externally. Machinists and tool-and-die professionals use this end mill in manual and CNC milling operations where a standard-length, large-diameter tool is required.

This end mill is rated for use on steel, stainless steel, cast iron, and high-temperature alloys. Its centercutting geometry allows plunge entry directly into the workpiece, making it viable for slot milling, pocketing, and profiling operations. The right-hand cut and right-hand spiral flute configuration is standard for conventional vertical milling setups. With a 0.75-inch shank diameter and a 4.125-inch overall length, this is a regular-length tool that fits standard ER and end mill holders sized for 3/4-inch shanks.

Key Features

• M42 cobalt construction for improved heat and wear resistance versus standard M2 HSS
• Centercutting design allows direct plunge cuts without a pre-drilled entry point
• 30-degree helix angle promotes smooth chip flow and reduced cutting forces
• Bright/uncoated finish compatible with external coolant and cutting oil use
• Right-hand cut and right-hand flute for standard milling machine spindle direction
• Single-end configuration with 2 flutes optimized for slotting and roughing in tough materials

Compatibility

Designed for use in standard end mill holders and collet chucks accepting a 3/4-inch shank diameter. Suitable for steel, stainless steel, cast iron, and high-temperature alloy workpieces in manual and CNC milling machines.

Installation Notes

Installation should be performed by a qualified machinist following shop safety protocols. Secure the shank fully into the holder to the minimum recommended engagement depth and torque the set screw or collet nut per the holder manufacturer specification. Verify spindle direction is right-hand before engaging the cut. Do not run this tool without confirming workholding is secure and appropriate cutting parameters for the workpiece material are set.
