Value Collection 723-6859 Roughing End Mill 1-1/2 in 6 Flute

Product Description

The VALUE COLLECTION 723-6859 is a single-end roughing end mill designed for aggressive material removal in milling operations. Manufactured from M42 cobalt high-speed steel and finished with a titanium nitride (TiN) coating, this tool delivers extended wear resistance and heat tolerance in demanding cutting environments. The 1.5-inch mill diameter pairs with 6 flutes and a 2-inch length of cut to produce high chip loads per pass while reducing chatter on workpiece surfaces. Machinists and toolroom operators use this style of end mill when rapid stock removal is the priority before a finishing pass.

This roughing end mill is suited for milling operations on ferrous and non-ferrous metals in both manual and CNC machining centers. The 1.25-inch shank diameter accommodates standard end mill holders and collet chucks. With a right-hand cutting direction and right-hand flute helix, the tool is compatible with conventional vertical milling machine setups and CNC knee mills. The 4.5-inch overall length provides adequate reach for most workholding configurations without excessive overhang.

Key Features

• M42 cobalt HSS construction for improved red hardness and tool life versus standard M2 HSS
• TiN coating reduces friction and extends cutting edge life in abrasive materials
• 6-flute configuration maximizes metal removal rate per revolution
• Single-end design with right-hand cut and right-hand flute direction
• 1.25-inch shank diameter fits standard end mill holders and collet chucks
• Non-center-cutting geometry — requires a pre-drilled or milled entry point

Compatibility

Designed as an OEM-style replacement or direct-use roughing end mill for standard vertical milling machines and CNC machining centers accepting a 1.25-inch shank end mill holder or collet.

Installation Notes

This end mill is installed by a qualified machinist or toolroom technician using an appropriate end mill holder or collet chuck rated for the 1.25-inch shank. Ensure the spindle is fully stopped and the machine is locked out before inserting or removing the tool. Verify holder runout with a dial indicator before commencing cuts, as excessive runout accelerates flute wear. Because this tool is non-center-cutting, always enter the workpiece from an existing edge or pre-drilled hole — do not plunge directly into solid material.
