Value Collection 723-1081 Square End Mill 7/8in Cobalt

Product Description

The VALUE COLLECTION 723-1081 is a cobalt square end mill designed for metal removal in demanding machining applications. Built from M42 cobalt high-speed steel, it delivers heat and wear resistance beyond standard HSS tooling. The cutter measures 7/8 inches in diameter with a 1-1/2 inch length of cut and a 3-1/2 inch overall length. The 1/2 inch shank fits standard end mill holders and collet chucks. Two right-hand spiral flutes at a 30-degree helix angle promote efficient chip evacuation and reduce cutting forces across a range of ferrous workpiece materials. The bright, uncoated finish suits applications where coating buildup or contamination must be avoided.

This end mill is suited for milling slots, pockets, profiles, and shoulders in steel, stainless steel, cast iron, and high-temperature alloys. The single-end, regular-length geometry makes it a practical choice for general-purpose CNC machining centers and manual knee mills operating in job shop, maintenance, and production environments. The centercutting design allows plunge entry directly into the workpiece without pre-drilling.

Key Features

• M42 cobalt HSS construction resists heat and abrasion when cutting steel, stainless steel, cast iron, and high-temp alloys
• 30-degree right-hand helix promotes smooth chip flow and reduces cutting pressure
• Centercutting geometry allows direct plunge milling without a starter hole
• Bright, uncoated finish reduces buildup risk and simplifies regrinding
• Two-flute design provides larger chip clearance in slotting and deep-pocket operations
• Single-end, regular-length proportions offer rigidity for general-purpose work

Compatibility

Designed as a general-purpose replacement or production end mill compatible with standard 1/2 inch end mill holders, collet chucks, and Weldon-style tool holders used in CNC machining centers and manual milling machines.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the machine spindle is fully stopped and locked out before mounting or removing the tool. Seat the shank fully in the holder and torque set screws or collet nuts to the tool holder manufacturer specification. Inspect the cutting edges for chips or damage before each use, and confirm workpiece clamping is secure before initiating a cut.
