Value Collection 723-1088 Square End Mill Cobalt 7/8 in

Product Description

The VALUE COLLECTION 723-1088 is a cobalt square end mill designed for material removal in ferrous and high-temperature alloy applications. Built from M42 cobalt high-speed steel, this single-end tool features a 7/8-inch cutting diameter, a 1-1/2-inch length of cut, and a 30-degree right-hand spiral helix. The bright, uncoated finish suits applications where coating is not required or where re-sharpening is anticipated. Centercutting geometry allows plunge entry as well as conventional peripheral milling. Machinists and tool-and-die professionals use this geometry for slotting, profiling, and pocketing operations across a range of shop environments.

This end mill is suited for milling steel, stainless steel, cast iron, and high-temperature alloys in job shop, production, and maintenance machining contexts. The 7/8-inch shank diameter matches standard R8, CAT, BT, and collet-style toolholders found on manual knee mills and CNC machining centers. Regular-length geometry keeps overhang minimal, supporting stable cuts in moderate-depth applications. The Series VCCC-C-2 designation identifies this as part of a fractional-inch cobalt line intended for general-purpose trade use.

Key Features

• M42 cobalt steel construction for improved heat and wear resistance compared to standard M2 HSS
• 30-degree right-hand helix promotes efficient chip evacuation and smooth cutting action
• Centercutting design allows direct plunge milling without a pre-drilled entry point
• Bright/uncoated finish compatible with re-sharpening and coolant-free applications
• 2-flute configuration provides generous chip clearance for slotting and full-width cuts
• Single-end tool with 7/8-inch shank diameter for rigid toolholder engagement

Compatibility

Designed as a general-purpose replacement or standard-stock end mill for manual and CNC milling machines accepting a 7/8-inch straight shank. Primary workpiece materials are steel, stainless steel, cast iron, and high-temperature alloys per ISO material codes P, M, K, and S.

Installation Notes

Installation is performed by qualified machinists following standard toolroom procedures. Ensure the machine spindle and toolholder are powered down and fully stopped before inserting or removing the end mill. Verify collet or end-mill holder bore matches the 7/8-inch shank diameter and that the tool is seated to the full recommended engagement depth before tightening. Confirm cutting direction is set to right-hand rotation to match the flute geometry before initiating a cut.
