Value Collection 723-5738 Roughing End Mill 0.5 in Cobalt

Product Description

The VALUE COLLECTION 723-5738 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, it delivers the heat resistance and edge retention needed for ferrous and tough alloy cuts. The cutter measures 0.5 inches in diameter with a 0.5-inch shank, a 2.5-inch length of cut, and a 4.5-inch overall length. Four right-hand flutes with a right-hand cutting direction produce coarse chip loads that clear material quickly. Licensed machinists and toolroom professionals install this type of cutter in vertical machining centers, knee mills, and manual bridgeports.

This roughing end mill is suited for roughing passes on steel, stainless, cast iron, and similar materials where stock removal rate matters more than surface finish. The coarse flute profile breaks chips aggressively, reducing heat buildup and tool deflection during heavy cuts. It is not center-cutting, so ramp or helical entry is required when plunging into a workpiece. Shops running production roughing cycles or prototype work that demands fast material removal before a finishing pass will find this geometry appropriate for those applications.

Key Features

• M42 cobalt high-speed steel construction for elevated heat and wear resistance
• 4-flute roughing geometry for high chip load and fast material removal
• 0.5-inch diameter with matching 0.5-inch shank for standard collet and end mill holder fitment
• 2.5-inch length of cut supports deep slotting and side-milling passes
• Bright, uncoated finish suitable for use with or without cutting fluid
• Right-hand cut and right-hand flute direction, standard for conventional milling setups

Compatibility

Designed as a standard-geometry replacement roughing end mill compatible with any milling machine spindle or tool holder that accepts a 0.5-inch shank end mill, including ER collet chucks, end mill holders, and Weldon-style holders.

Installation Notes

Installation is performed by machinists or toolroom technicians. Power down and lock out the machine spindle before changing tooling. Seat the shank fully into the holder and torque the set screw or collet nut to the machine manufacturer's specification using the correct wrench. Because this end mill is not center-cutting, avoid direct axial plunge moves and use a ramping or helical entry path instead.
