Value Collection 723-5817 Roughing End Mill 1-1/8 in Cobalt

Product Description

The VALUE COLLECTION 723-5817 is a single-end cobalt roughing end mill designed for aggressive material removal in milling operations. Built from M42 cobalt high-speed steel with a bright, uncoated finish, this tool features a 1.125-inch cutting diameter and 6 flutes configured for roughing cuts. The 2-inch length of cut and 0.75-inch shank diameter suit it for use in vertical mills and machining centers where high chip loads and interrupted cuts are routine. Machinists and toolroom operators use this style of end mill when stock removal rate takes priority over surface finish.

This end mill is suited for roughing passes on ferrous and non-ferrous metals in both job-shop and production environments. The right-hand cutting and right-hand flute direction are standard for conventional milling machine spindles. The non-centercutting geometry means it is intended for peripheral cuts and side milling rather than plunge operations. It is a practical choice for removing large amounts of material before a finish pass with a standard end mill.

Key Features

• M42 cobalt construction for improved heat and wear resistance compared to standard HSS
• 6-flute design increases feed rate capability during roughing passes
• 1.125-inch mill diameter with 2-inch length of cut handles significant depth-of-cut requirements
• Bright, uncoated finish — compatible with a wide range of cutting fluids and lubricants
• Right-hand cut, right-hand flute direction for standard milling machine spindles
• Non-centercutting geometry — suited for side milling and peripheral roughing, not plunge entry

Compatibility

Designed as a standard roughing end mill with a 0.75-inch shank diameter, fitting collets and end mill holders sized for that shank on vertical mills and machining centers with compatible spindle tooling.

Installation Notes

Installation should be performed by a qualified machinist or toolroom professional. Secure the shank fully in a clean, undamaged collet or end mill holder and confirm runout before cutting. Verify spindle speed and feed rate against published data for the workpiece material and tool diameter before engaging the cut. Because this is a non-centercutting tool, do not use it for plunge milling without a pre-drilled entry point.
