Value Collection 723-5859 Roughing End Mill 1.5 in 6 Flute Cobalt

Product Description

The VALUE COLLECTION 723-5859 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 and wear resistance required for cutting tough ferrous and non-ferrous materials. The mill measures 1.5 inches in diameter with a 1.25-inch shank diameter, a 2-inch length of cut, and a 4.5-inch overall length. The 6-flute configuration produces a chip-breaking geometry that reduces cutting forces and minimizes chatter during heavy roughing passes.

This end mill is suited for manual and CNC vertical milling machines, knee mills, and machining centers where high-stock-removal roughing is required. The right-hand cutting and right-hand flute direction make it compatible with standard spindle setups. It is a single-end, non-centercutting tool, meaning it is intended for peripheral and side milling rather than plunge cutting. Machinists, tool-and-die workers, and production machine operators will find it appropriate for roughing steel, alloy steel, and similar materials before finishing passes.

Key Features

• M42 cobalt construction resists heat buildup during high-feed roughing cuts
• 6-flute design increases chip load capacity and reduces vibration
• Bright/uncoated finish suits applications where coating is not required or would interfere with dimensional tolerances
• Right-hand cut and right-hand flute direction for standard milling setups
• Non-centercutting geometry — optimized for side and peripheral milling only
• Single-end configuration with a 1.25-inch shank for secure toolholder engagement

Compatibility

Designed as a standard replacement or stock roughing end mill for milling machines and CNC machining centers that accept a 1.25-inch shank diameter toolholder or collet system.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer's toolholder torque and runout specifications. Ensure the spindle is fully powered down and locked before changing end mills. Inspect the shank and toolholder bore for chips or contamination before seating the tool. Because this is a non-centercutting end mill, do not use it for direct plunge operations — use a center-cutting or drill to establish entry points first.
