Value Collection 724-5266 Roughing End Mill 1in 5 Flute Cobalt

Product Description

The VALUE COLLECTION 724-5266 is a single-end roughing and finishing cobalt end mill designed for aggressive material removal and finish passes in a single tool. Built from M42 cobalt high-speed steel and coated with Titanium Nitride (TiN), it delivers extended cutting life and heat resistance compared to standard HSS tooling. The 1-inch diameter cutter features 5 right-hand flutes with a 30-degree helix angle and a square end profile. The Weldon flat shank provides a positive, slip-resistant grip in the tool holder. This end mill is installed and operated by machinists and tool-and-die professionals working on mills and machining centers.

This end mill is suited for milling applications in ferrous and non-ferrous metals where both roughing stock removal and finish quality are required in the same operation. The 3-inch length of cut accommodates deeper shoulder and slot milling passes. The right-hand cutting direction and non-centercutting geometry make it appropriate for peripheral and side milling operations rather than plunge cutting. Typical applications include profiling, contouring, and slotting on manual or CNC vertical mills.

Key Features

• M42 cobalt HSS construction for improved heat and wear resistance over standard M2 HSS
• TiN coating reduces friction and extends cutting tool life
• 5 right-hand flutes with 30-degree helix for efficient chip evacuation
• Square end geometry for shoulder milling, slotting, and profiling
• Weldon flat shank prevents tool pullout in side-lock holders
• Single-end design — 3-inch length of cut, 5.5-inch overall length

Compatibility

Designed as an OEM-style replacement or direct substitute for 1-inch diameter, 5-flute cobalt roughing end mills with a Weldon flat shank and square end profile used in standard end mill holders and side-lock tool holders on vertical mills and machining centers.

Installation Notes

Installation should be performed by a qualified machinist following shop safety procedures. Secure the Weldon flat shank in a side-lock or set-screw end mill holder, ensuring the flat is aligned with the locking screw for positive engagement. Verify spindle speed and feed rate are appropriate for the workpiece material and cutter diameter before starting the cut. This tool is not centercutting — do not use for direct plunge operations.
