Value Collection 724-4023 End Mill 1/4 in 4 Flute Cobalt

Product Description

The VALUE COLLECTION 724-4023 is a 4-flute cobalt roughing finishing end mill designed for aggressive material removal and finish milling in a single tool. Built from M42 cobalt high-speed steel, it handles tough ferrous alloys and hardened materials that standard HSS tooling cannot efficiently cut. The 1/4 inch cutting diameter and 30-degree helix angle promote smooth chip evacuation and reduced cutting forces. The bright uncoated finish suits applications where coating adhesion or heat buildup is not a concern. Licensed machinists and tool-and-die professionals use this style of end mill for profiling, slotting, and ramping cuts on vertical mills and CNC machining centers.

This end mill is suited for milling operations in job shops, maintenance facilities, and production environments working with steel, stainless steel, and similar ferrous materials. The Weldon flat shank provides a positive mechanical lock in end mill holders and reduces tool pullout under high feed loads. Its single-end configuration and square end geometry make it a direct fit for standard milling chucks and collet holders accepting a 3/8 inch shank diameter.

Key Features

• M42 cobalt construction for heat resistance in hard and tough materials
• 4-flute design balances chip clearance and surface finish capability
• 30-degree helix angle promotes efficient chip evacuation and smooth cutting action
• Weldon flat shank prevents tool pullout in side-lock holders
• Square end geometry supports profiling, slotting, and shoulder milling
• Bright uncoated finish for general-purpose milling without coating concerns

Compatibility

Designed for use in standard end mill holders, Weldon-style side-lock holders, and collet chucks accepting a 3/8 inch shank diameter on vertical knee mills and CNC machining centers.

Installation Notes

Installation should be performed by a qualified machinist following machine tool manufacturer guidelines. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Secure the Weldon flat against the side-lock set screw to the manufacturer-specified engagement depth to prevent pullout under load. Verify runout with a dial indicator before beginning cuts when tight tolerances are required.
