Value Collection 723-4436 Roughing End Mill 3/8 in Cobalt

Product Description

The VALUE COLLECTION 723-4436 is a single-end roughing end mill designed for aggressive material removal in milling operations. Built from M42 cobalt high-speed steel with a bright, uncoated finish, this tool delivers the heat resistance and edge retention needed for roughing passes on steel, stainless, and other ferrous materials. The 3/8 inch diameter cutter features 3 flutes with a high helix, right-hand cutting geometry, and a 1-1/8 inch length of cut. Overall length is 2-13/16 inches. Centercutting capability allows plunge entry without a pre-drilled pilot hole. This tool is a staple for machinists and toolroom operators running manual mills, CNC machining centers, or knee mills.

This end mill is suited for roughing operations on ferrous metals in both job shop and production environments. The high-helix, right-hand flute geometry evacuates chips efficiently during deep roughing cuts, reducing heat buildup and extending tool life between passes. The 3/8 inch shank matches directly to standard ER collets, end mill holders, and Weldon-style holders found on most vertical milling machines and CNC machining centers. It is a good fit for slots, pockets, profiling, and side milling where fast stock removal is the priority before a finishing pass.

Key Features

• M42 cobalt HSS construction for elevated heat and wear resistance during roughing
• 3 flutes with high helix angle for aggressive chip evacuation
• Centercutting design allows direct plunge milling without a pilot hole
• Right-hand cut and right-hand flute direction for standard milling setups
• Bright, uncoated finish suitable for a wide range of ferrous workpiece materials
• Single-end configuration — 1-1/8 inch length of cut, 2-13/16 inch overall length

Compatibility

Designed as a standard-geometry replacement or stock tooling option for 3/8 inch end mill holders, ER collet chucks, and Weldon-style tool holders used on vertical milling machines and CNC machining centers requiring a 3-flute roughing end mill.

Installation Notes

Installation is performed by a machinist or toolroom technician. Ensure the spindle is fully stopped and power is locked out before changing tooling. Seat the shank fully into the collet or holder and torque the retention mechanism to the machine manufacturer specification. Confirm runout with a dial indicator before beginning a cut, as excessive runout accelerates edge wear on cobalt tooling.
