Value Collection 724-0086 Roughing End Mill 3/8 in 4 Flute Cobalt

Product Description

The VALUE COLLECTION 724-0086 is a single-end roughing end mill designed to remove material rapidly in milling applications. Built from M42 cobalt high-speed steel with a bright, uncoated finish, it delivers solid wear resistance and heat tolerance in ferrous and non-ferrous machining. The cutter measures 3/8 inch in diameter with a 1-1/8 inch length of cut and a 2-15/16 inch overall length. Four right-hand flutes with a roughing profile break chips aggressively, reducing cutting forces and vibration during heavy stock removal passes. Center-cutting geometry allows plunge entry. This tool is installed by machinists, toolmakers, and CNC operators in production and job-shop environments.

This roughing end mill is suited for horizontal, vertical, and CNC milling machines in both manual and automated setups. It handles roughing passes on steels, alloy steels, and other materials where controlled chip load and thermal resistance are priorities. The 3/8 inch shank diameter matches standard ER collets, end mill holders, and milling chucks without adapters. Single-end configuration means one cutting end with a straight shank on the opposite side.

Key Features

• M42 cobalt HSS construction for elevated heat and wear resistance versus standard M2 tooling
• Roughing flute profile reduces cutting forces and controls chip formation during heavy passes
• Center-cutting design permits direct plunge entry without a pre-drilled pilot hole
• Right-hand cut and right-hand flute direction compatible with conventional milling machine spindles
• Bright, uncoated finish suitable for use with or without coolant
• Equal shank and cutter diameter at 3/8 inch simplifies toolholder selection

Compatibility

Designed as an OEM-style replacement or direct-use roughing end mill for standard milling applications requiring a 3/8 inch single-end cobalt cutter with a 3/8 inch straight shank.

Installation Notes

Install by a qualified machinist using a properly torqued collet chuck or end mill holder rated for the spindle speed and material being cut. Ensure the milling machine spindle is fully stopped and the machine is locked out before changing tooling. Verify runout with a dial indicator after seating to confirm proper holder engagement. Follow shop-specific feeds, speeds, and depth-of-cut parameters for the workpiece material and machine capability.
