Value Collection 723-3653 Cobalt Square End Mill 3/32 in

Product Description

The VALUE COLLECTION 723-3653 is a cobalt square end mill designed for precision milling operations in metal fabrication and machining applications. Built from M42 cobalt high-speed steel, this single-end tool features a 3/32 inch (0.0938 inch) cutting diameter and a 1/4 inch length of cut, making it well suited for tight-tolerance slotting, profiling, and peripheral milling in harder materials. The 3-flute geometry and 30-degree helix angle promote efficient chip evacuation while maintaining a strong cutting edge. The bright/uncoated finish keeps the surface true to the base material. Overall length is 1-1/4 inches with a 1/4 inch shank diameter.

This end mill is intended for use in manual mills, CNC machining centers, and benchtop milling equipment where small-diameter tooling is required. The long-length designation and 3/32 inch diameter make it particularly useful for reaching into narrow slots or tight pockets in steel, stainless steel, cast iron, and other ferrous alloys. Machinists, tool and die makers, and production CNC operators working with harder workpiece materials will find the M42 cobalt construction appropriate where standard HSS tooling falls short.

Key Features

• M42 cobalt construction for improved hardness and heat resistance compared to standard HSS
• 3-flute design balances chip clearance with cutting edge strength at small diameters
• 30-degree right-hand spiral helix promotes smooth chip flow and reduced chatter
• Centercutting geometry allows plunge entry into the workpiece
• Bright/uncoated finish maintains tight dimensional tolerances on the cutting edges
• Single-end configuration with 1/4 inch straight shank for standard collet or end mill holder use

Compatibility

Designed as an OEM-style replacement or standard tooling option for manual and CNC milling setups requiring a 1/4 inch shank, small-diameter square end mill in cobalt or high-speed steel grades.

Installation Notes

Install in a compatible collet or end mill holder rated for a 1/4 inch shank diameter and confirm runout with a dial indicator before cutting. Ensure the spindle and quill are fully powered down and the machine is locked out before changing tooling. Follow the machine tool manufacturer guidelines for feed rate and spindle speed appropriate to the workpiece material and tool diameter. Do not exceed the recommended depth of cut for the 1/4 inch length of cut specification.
