Value Collection 724-4088 Roughing End Mill 3/8 in 4 Flute Cobalt

Product Description

The VALUE COLLECTION 724-4088 is a roughing finishing end mill designed for aggressive material removal and finish-quality results in a single tool. Built from M42 cobalt high-speed steel, it handles tough ferrous and non-ferrous materials where standard HSS tooling falls short. The 4-flute, square-end geometry with a 30-degree helix angle provides efficient chip evacuation and smooth cutting action. With a 3/8-inch mill diameter and 1.375-inch length of cut, this end mill suits a range of slot milling, peripheral milling, and profiling operations. It ships in a bright, uncoated finish and is configured for right-hand cutting with a right-hand flute direction.

This end mill is suited for use in vertical machining centers, manual mills, and CNC equipment requiring a 3/8-inch shank. The Weldon flat shank provides positive drive and minimizes pullout in side-lock toolholders. It is a single-end tool and is not centercutting, so plunge entry into solid material is not recommended without a pre-drilled pilot. Typical applications include roughing passes on steel, alloy steel, stainless, and similar workpiece materials in job shop and production environments.

Key Features

• M42 cobalt material grade for heat and wear resistance in hard-to-machine alloys
• 4-flute square-end geometry for profiling, slotting, and peripheral milling
• 30-degree helix angle promotes smooth cutting and efficient chip flow
• Weldon flat shank for positive drive in side-lock toolholders
• Right-hand cut and right-hand flute direction, single-end configuration
• Bright uncoated finish — ready to use as supplied, no coating to manage

Compatibility

Designed as an OEM-style replacement or direct-use roughing finishing end mill for standard 3/8-inch collet or Weldon flat side-lock toolholders used in vertical mills and machining centers.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Ensure the spindle is fully powered down and locked out before changing tooling. Confirm the Weldon flat is properly aligned with the setscrew in the toolholder to prevent pullout under load. Because this tool is not centercutting, avoid direct plunge cuts into solid material without a pre-drilled entry point.
