Value Collection 723-5538 Roughing End Mill 1-1/4 in 6 Flute

Product Description

The VALUE COLLECTION 723-5538 is a single-end cobalt roughing end mill designed for aggressive stock removal on ferrous and non-ferrous metals. Built from M42 cobalt high-speed steel, it delivers heat and wear resistance needed for heavy interrupted cuts and harder workpiece materials. The 1.25-inch diameter cutter carries 6 coarse-pitch flutes in a right-hand cutting, right-hand flute configuration, with a 2-inch length of cut and a 3/4-inch shank diameter. The bright, uncoated finish is suited for applications where coating adhesion to the workpiece is a concern. Machinists and toolroom professionals install this type of end mill on vertical knee mills, CNC machining centers, and manual bridgeports for roughing passes before finishing operations.

This roughing end mill is intended for single-end use and is not center-cutting, meaning it is suited for peripheral and side milling rather than plunge cuts. The coarse-pitch flute geometry breaks chips aggressively and reduces cutting forces, making it effective for hogging material on steel, stainless, and tough alloy workpieces in both job shop and production environments. A 4.5-inch overall length provides standard reach for most milling fixtures without sacrificing rigidity.

Key Features

• M42 cobalt HSS construction for improved heat resistance over standard M2 high-speed steel
• 6 coarse-pitch flutes for aggressive chip breaking and high material removal rates
• 1.25-inch milling diameter with a 2-inch length of cut
• 3/4-inch straight shank for use in standard end mill holders and collet chucks
• Right-hand cut, right-hand flute orientation for conventional milling setups
• Bright uncoated finish — no coating buildup concerns on sticky or abrasive materials

Compatibility

Designed as an OEM-style replacement or standard tooling selection for milling machines accepting a 3/4-inch shank end mill holder or collet, in both manual and CNC vertical milling applications.

Installation Notes

Installation is performed by qualified machinists or toolroom personnel. Secure the 3/4-inch shank in a properly sized end mill holder or collet chuck, ensuring full and even shank engagement before tightening. Confirm spindle speed and feed rate are set per material and cutter diameter recommendations before engaging the cut. This tool is not center-cutting — do not use for direct plunge operations.
