Value Collection 720-1407 Ball End Mill 5/16 in 2 Flute Hss

Product Description

The VALUE COLLECTION 720-1407 is a single-end ball end mill designed for milling contoured surfaces, slots, and three-dimensional profiles in metalworking applications. Ground from M2 high speed steel with a bright/uncoated finish, this tool offers a 5/16-inch cutting diameter and a 3/4-inch length of cut. The 2-flute spiral geometry provides efficient chip evacuation and is well suited for profiling, plunge cuts, and finish passes in ferrous and non-ferrous materials. Right-hand cutting and right-hand flute direction follow standard conventions for most vertical and horizontal milling setups. Machinists, tool and die makers, and general machine shop operators are the primary users.

This end mill is used in standard milling machine and CNC machining center applications where a ball nose profile is required to produce radii, fillets, and complex contoured geometry. The 3/8-inch shank diameter fits common R8, ER, and side-lock toolholders found in most shop environments. The standard-length OAL of 2-1/2 inches keeps the tool rigid and minimizes deflection during light-to-medium material removal on steel, aluminum, brass, and similar workpiece materials.

Key Features

• 5/16-inch ball nose cutting diameter for profiling radii and contoured surfaces
• M2 high speed steel construction provides good wear resistance and toughness
• 2-flute spiral design promotes chip flow and suits slotting and profiling cuts
• Right-hand cut and right-hand helix for use with standard spindle rotation
• Bright/uncoated finish — suitable for general-purpose machining without added coating cost
• Single-end configuration with 3/8-inch straight shank for broad toolholder compatibility

Compatibility

Designed as a general-purpose replacement or production ball end mill for milling machines and CNC machining centers accepting a 3/8-inch shank diameter toolholder.

Installation Notes

Installation is performed by qualified machinists or CNC operators. Ensure the spindle is fully stopped and the machine is powered down or placed in an E-stop state before changing tooling. Seat the shank fully into the toolholder and verify runout with a dial indicator before beginning a cut. Follow the machine manufacturer's recommended clamping torque for the specific toolholder type in use.
