Value Collection 724-2093 Roughing End Mill 7/16 in Cobalt

Product Description

The VALUE COLLECTION 724-2093 is a single-end roughing end mill designed for aggressive material removal in milling operations. Manufactured from M42 cobalt high-speed steel with a bright, uncoated finish, it measures 7/16 inches (0.4375 inches) in diameter with a 3/8-inch shank diameter. The cutter features 3 flutes and a 1-inch length of cut, delivering a 2-5/16-inch overall length. The roughing geometry breaks chips into smaller segments, reducing cutting forces and heat buildup compared to standard end mills. Machinists and tool-and-die professionals rely on this style of cutter for roughing passes in steel, stainless, and other ferrous materials where cobalt grades outperform standard HSS tooling.

This end mill is suited for use in vertical machining centers, knee mills, and manual or CNC milling machines where roughing passes precede finish milling. The 3/8-inch straight shank fits standard end mill holders, collet chucks, and Weldon-style holders commonly found in job shops and production environments. It is a single-end tool intended for right-hand cutting with right-hand flute direction, and it is not center-cutting, meaning it is not designed for direct plunge entry.

Key Features

• M42 cobalt construction for heat resistance and wear life in ferrous materials
• Roughing geometry reduces cutting forces and chip load per flute
• 3 flutes with right-hand cut and right-hand helix for efficient chip evacuation
• Bright, uncoated finish suitable for use with cutting fluid or dry in appropriate materials
• 3/8-inch shank diameter fits widely available end mill holders and collet chucks
• Not center-cutting — designed for peripheral milling and side milling passes

Compatibility

Designed as a standard-shank roughing end mill compatible with 3/8-inch end mill holders, ER collet chucks, and Weldon-style toolholders used in vertical milling machines and CNC machining centers.

Installation Notes

Installation should be performed by a qualified machinist following shop safety protocols. Ensure the machine spindle is fully stopped and locked out before changing tooling. Confirm the holder is clean and free of chips or burrs before seating the shank, and torque set screws or collet nuts to the toolholder manufacturer's specification. Because this tool is not center-cutting, avoid plunge cuts directly into solid material.
