Value Collection 320-3750 Ball End Mill 5/8 in 4 Flute Hss

Product Description

The VALUE COLLECTION 320-3750 is a single-end ball end mill designed for milling contoured surfaces, slots, and complex 3D profiles in a wide range of materials. Built from high speed steel (HSS), this end mill features a 5/8 inch cutting diameter, a 1-5/8 inch length of cut, and a 4-flute spiral geometry that balances material removal rate with surface finish quality. The bright, uncoated finish makes it well suited for general-purpose milling applications where lubrication is applied at the point of cut. A right-hand cutting and right-hand flute direction are standard. Machinists and tool-and-die professionals are the primary installers and operators of this tooling.

This ball end mill is used in vertical and horizontal milling machines, CNC machining centers, and manual knee mills for profiling, contouring, and pocketing operations in ferrous and non-ferrous metals, plastics, and composites. The 5/8 inch shank diameter mates directly to standard ER collets, end mill holders, and side-lock arbors of the same bore size. The 3-3/4 inch overall length provides adequate reach for most standard workholding setups without introducing excessive tool deflection.

Key Features

• 5/8 inch ball nose cutting diameter for contour and profile milling
• 4-flute spiral geometry balances chip evacuation and finish quality
• High speed steel construction suitable for general-purpose milling
• Bright, uncoated finish compatible with most cutting fluids and lubricants
• Right-hand cut and right-hand flute direction for standard spindle rotation
• Single-end configuration with 3-3/4 inch overall length and standard length type

Compatibility

Designed as a standard replacement or production tooling option for any milling setup requiring a 5/8 inch shank, single-end ball end mill in high speed steel. Compatible with ER collet systems, end mill holders, and side-lock arbors bored to 5/8 inch.

Installation Notes

Installation is performed by a machinist or CNC operator. Always power down and lock out the spindle before changing tooling. Ensure the shank is fully seated in the holder to the recommended grip length and that set screws or collet nuts are torqued per the toolholder manufacturer specifications. Inspect the cutting edges for chips or wear before use and confirm proper coolant flow is directed to the cutting zone.
