Value Collection 724-1092 Roughing End Mill 3/8 in Cobalt

Product Description

The VALUE COLLECTION 724-1092 is a single-end roughing end mill designed for aggressive material removal in ferrous and non-ferrous metals. Built from M42 cobalt high-speed steel with a TiN coating, it runs hotter and harder than standard HSS tooling without rapid edge breakdown. The 3/8 inch diameter, 4-flute geometry produces a coarse chip load that clears material fast while reducing heat buildup at the cutting edge. With a 1.625 inch length of cut and 3.1875 inch overall length, it fits standard milling chucks and collet holders used in most vertical mills and machining centers. Center-cutting capability allows plunge entry without a pre-drilled pilot hole.

This end mill suits production and job-shop environments where roughing passes on steel, stainless, and hard alloys demand a durable, cost-effective tool. It is appropriate for CNC vertical mills, knee mills, and manual bridgeport-style machines running right-hand cutting and right-hand flute configurations. Machinists and toolroom technicians use this style of roughing end mill as a first-pass tool before finishing with a standard end mill.

Key Features

• M42 cobalt HSS construction handles elevated cutting temperatures better than standard M2 HSS
• TiN coating reduces friction and extends edge life on ferrous materials
• 4-flute right-hand geometry with right-hand flute direction for conventional milling setups
• Center-cutting design allows direct plunge entry without pilot drilling
• 3/8 inch shank diameter matches 3/8 inch collets and end mill holders directly
• Single-end configuration — replace when worn, no reversing

Compatibility

Designed as a standard 3/8 inch shank roughing end mill compatible with any milling machine spindle, collet chuck, or end mill holder accepting a 3/8 inch straight shank.

Installation Notes

Installation is performed by toolroom machinists or CNC setup technicians. Power down and lock out the machine spindle before loading or removing any end mill. Seat the shank fully in the collet or holder and torque the retention nut to the tool holder manufacturer specification. Inspect the cutting edges and TiN coating for chips or wear before each use — do not run a damaged end mill at speed.
