Value Collection 724-6526 Roughing End Mill 3/4 in Cobalt

Product Description

The VALUE COLLECTION 724-6526 is a single-end roughing end mill designed for aggressive material removal in milling operations. Built from M42 cobalt high-speed steel and finished with a TiN coating, it handles tough ferrous and non-ferrous materials where standard HSS tooling loses edge life. The 3/4 inch diameter, 3-flute geometry produces coarse, wave-pattern cuts that break chips efficiently and reduce heat buildup during heavy roughing passes. With a 3 inch length of cut and 5-1/4 inch overall length, it provides reach suited to moderate-depth pocketing and profiling work on vertical mills and CNC machining centers.

This end mill is used in general machining environments for roughing operations on steel, stainless, cast iron, and similar materials. The right-hand cutting direction and high-helix flute geometry combine to pull chips away from the cut zone, reducing re-cutting and tool deflection. It is center-cutting, allowing plunge entry without a pre-drilled pilot hole. Machinists and tool-and-die professionals typically deploy this type of tooling in production shops, job shops, and maintenance machining settings where maximizing metal removal rate before a finishing pass is the priority.

Key Features

• M42 cobalt steel construction for extended tool life in hard and abrasive materials
• TiN coating reduces friction and improves wear resistance at the cutting edge
• 3-flute design balances chip evacuation with core strength in roughing applications
• High-helix, right-hand flute direction promotes efficient chip flow and reduced heat
• Center-cutting geometry allows direct plunge entry into the workpiece
• 3/4 inch shank diameter matches standard collets and end mill holders

Compatibility

Designed as a standard 3/4 inch shank roughing end mill compatible with collet chucks, end mill holders, and milling machine spindles accepting 3/4 inch straight-shank tooling.

Installation Notes

Installation should be performed by a qualified machinist following safe tooling change procedures. Power down and lock out the machine spindle before seating or removing the end mill. Ensure the shank is fully seated in the holder to the recommended engagement depth and that the set screw or collet nut is properly torqued per the toolholder manufacturer specifications. Inspect the cutting edges for chips or damage before each use.
