Value Collection 724-0143 Roughing End Mill 5/8 in Cobalt

Product Description

The VALUE COLLECTION 724-0143 is a single-end cobalt roughing end mill designed for aggressive material removal in milling applications. Built from M42 cobalt high-speed steel, it delivers the heat and wear resistance required for cutting tough ferrous and non-ferrous metals. The 4-flute, right-hand cutting geometry with a bright uncoated finish provides a sharp, strong edge suited for roughing passes where chip evacuation and edge durability matter. At 0.625 inches in diameter with a 1.25-inch length of cut, this tool fits standard 5/8-inch collets and tool holders. It is center-cutting, allowing plunge entry without a pre-drilled pilot hole.

This roughing end mill is a practical choice for job shop machinists, tool-and-die makers, and maintenance machinists running manual or CNC knee mills, vertical machining centers, and similar setups. It suits roughing operations on steel, alloy steel, cast iron, and comparable materials where high stock removal rates are the priority before a finish pass. The 3.375-inch overall length provides adequate reach for most standard workholding setups without sacrificing rigidity.

Key Features

• M42 cobalt construction for heat resistance during high-load roughing cuts
• 4-flute, right-hand cut and right-hand flute direction for stable chip flow
• Center-cutting capability allows direct plunge entry into the workpiece
• Bright uncoated finish — ready for use with cutting fluid or neat oil
• Single-end design with 5/8-inch shank diameter matching the cutter diameter
• 3.375-inch overall length with 1.25-inch length of cut

Compatibility

Designed as an OEM-style roughing end mill for use in standard 5/8-inch end mill holders, collet chucks, or Weldon-style side-lock holders on vertical milling machines and CNC machining centers.

Installation Notes

Installation should be performed by a qualified machinist following established shop safety procedures. Ensure the spindle is fully stopped and the machine is powered down before inserting or removing the tool. Verify the holder is clean and free of chips before seating the shank, and confirm the tool is secured to the appropriate torque specification for the holder type in use. Do not exceed the recommended depth of cut or feed rate for the workpiece material.
