Value Collection 723-3661 Cobalt Square End Mill 7/32 in

Product Description

The VALUE COLLECTION 723-3661 is a cobalt square end mill designed for precision milling operations in metalworking and machining applications. Built from M42 cobalt high-speed steel, this single-end tool features a 7/32 inch (0.2188 inch) cutting diameter and a 1/2 inch length of cut, making it well suited for slotting, profiling, and peripheral milling in harder workpiece materials. The bright, uncoated finish is standard for cobalt tooling used across a range of general-purpose metal removal tasks. With three flutes and a 30-degree right-hand spiral helix, it balances chip evacuation with rigidity in short-to-medium depth cuts. Machinists and tool-and-die professionals are the primary users of this tool.

This end mill is appropriate for use on manual mills and CNC machining centers handling ferrous and non-ferrous metals, stainless steel, and harder alloys where cobalt-grade tooling is specified over standard HSS. The long-series length designation and center-cutting capability allow it to plunge directly into material as well as perform conventional side milling. The 1/4 inch shank diameter fits standard collets and end mill holders commonly found in light-to-medium duty milling setups. It is sold as a single-piece unit and is intended for shop environments where tooling is selected by material grade and geometry rather than coated tooling alternatives.

Key Features

• M42 cobalt construction for improved heat and wear resistance compared to standard HSS
• 3-flute geometry supports efficient chip removal in slotting and profiling cuts
• 30-degree right-hand helix angle for smooth cutting action
• Center-cutting design allows direct plunge entry into workpiece material
• Bright/uncoated finish suitable for use with or without cutting fluid
• Long-series length type provides added reach for deeper setups

Compatibility

Designed as a standard fractional-inch shank end mill compatible with collet chucks and end mill holders accepting a 1/4 inch shank diameter on manual knee mills and CNC vertical machining centers.

Installation Notes

Installation and tool changes should be performed by a qualified machinist with the spindle fully stopped and the machine in a locked-out, de-energized state. Use a properly sized collet or end mill holder to secure the 1/4 inch shank with adequate tool stick-out while minimizing deflection. Verify runout with a dial indicator before beginning production cuts. Follow applicable shop safety standards and machine manufacturer guidelines for tool holding torque and spindle speed selection.
