Value Collection 724-2266 Roughing End Mill 1 in 5 Flute Cobalt

Product Description

The VALUE COLLECTION 724-2266 is a single-end roughing end mill designed for aggressive material removal in ferrous and non-ferrous machining applications. Built from M42 cobalt high-speed steel with a bright/uncoated finish, this tool handles interrupted cuts and harder workpiece materials where standard HSS tooling falls short. It features a 1-inch mill diameter, 5-flute geometry, and a 3-inch length of cut, making it well suited for slotting, profiling, and roughing passes where chip load and heat resistance are priorities. The right-hand cutting and right-hand flute direction are standard for conventional CNC and manual milling setups.

This roughing end mill is intended for use in vertical machining centers, knee mills, and manual milling machines across job shop and production environments. The 5-flute configuration increases feed rate capability compared to 4-flute designs, while the roughing geometry breaks chips into smaller segments to reduce cutting forces and heat buildup. Machinists and toolroom operators working in steel, alloy steel, stainless, and similar hard materials will find this an appropriate roughing tool before a finishing pass.

Key Features

• M42 cobalt HSS construction for improved red hardness and wear resistance over standard M2 HSS
• 5-flute roughing geometry reduces cutting forces and improves chip evacuation
• 1-inch mill diameter with matching 1-inch shank diameter for direct collet or end mill holder mounting
• 3-inch length of cut supports deep pocket and slot roughing operations
• Right-hand cut, right-hand helix — compatible with standard spindle rotation on most mills
• Bright/uncoated finish suitable for use with cutting fluid in ferrous machining

Compatibility

Designed as an OEM-style replacement or standard tooling option for milling machines accepting a 1-inch straight shank end mill via collet chuck, end mill holder, or side-lock holder.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Seat the shank fully into the holder to the recommended engagement depth before tightening — never run a tool with insufficient shank engagement. Verify spindle speed and feed rate are appropriate for the workpiece material and tool diameter before beginning the cut; consult published speeds-and-feeds data for M42 cobalt end mills.
