Value Collection 724-5164 Roughing End Mill 11/16 in Cobalt

Product Description

The VALUE COLLECTION 724-5164 is a single-end roughing finishing end mill designed for material removal and finishing operations in one tool. Built from M42 cobalt high-speed steel and coated with Titanium Nitride (TiN), it delivers extended tool life in ferrous and hard materials. The 11/16 inch (0.6875 inch) cutting diameter, 4-flute configuration, and 30-degree helix angle combine to reduce cutting forces while maintaining surface finish quality. The Weldon flat shank provides positive drive and prevents slippage under heavy feeds. Licensed machinists and toolroom operators are the primary users of this end mill in manual or CNC milling applications.

This end mill is suited for roughing and finishing passes on steel, stainless, and other tough alloys in job shop, production machining, and toolroom environments. The square end geometry produces flat-bottomed slots, shoulders, and peripheral cuts. With a 1-5/8 inch length of cut and 3-3/4 inch overall length, it handles standard-depth pocketing and profiling operations without excessive overhang. The right-hand flute direction and right-hand cutting rotation are compatible with conventional milling machine and machining center setups.

Key Features

• M42 cobalt steel construction for heat and wear resistance in difficult-to-machine alloys
• Titanium Nitride (TiN) coating reduces friction and extends tool life
• 30-degree helix angle balances chip evacuation with cutting stability
• Weldon flat shank ensures secure tool holding and eliminates pullout
• Square end geometry for flat-bottom slots, shoulders, and profiling cuts
• Right-hand cut, right-hand flute, single-end configuration

Compatibility

Designed for use in standard Weldon flat end mill holders and compatible milling chucks on manual knee mills and CNC machining centers accepting a 5/8 inch shank diameter.

Installation Notes

Installation should be performed by a qualified machinist following shop safety procedures. Ensure the spindle is fully stopped and machine power is locked out before changing tooling. Secure the Weldon flat shank in a properly sized end mill holder and tighten set screws against the flat to the holder manufacturer's specification. Verify runout with a dial indicator before beginning the cut.
