Value Collection 320-3705 Ball End Mill 1/4 in 4 Flute Hss

Product Description

The VALUE COLLECTION 320-3705 is a single-end ball end mill designed for milling contoured surfaces, slots, and three-dimensional profiles in metalworking and machining applications. Built from high speed steel (HSS), this tool delivers reliable performance in general-purpose cutting operations. It features a 1/4 inch mill diameter, a 5/8 inch length of cut, and a 3/8 inch shank diameter, with a 2-1/2 inch overall length. The bright, uncoated finish suits standard cutting conditions where specialized coatings are not required. With four flutes in a right-hand spiral configuration, this end mill provides a balance of chip evacuation and surface finish quality. Machinists and CNC operators working in job shops, tool rooms, and production environments are the primary users.

This ball end mill is suited for use in vertical and horizontal milling machines, CNC machining centers, and manual knee mills. It is appropriate for profiling, contouring, and finishing passes on a variety of workpiece materials where an HSS tool meets the cutting speed and feed requirements. The standard length classification makes it compatible with common toolholders and collet systems that accept a 3/8 inch shank. This tool is sold as a single unit and is well suited for low-volume tool room use or as a replacement end mill in ongoing production.

Compatibility

Designed as a standard-shank replacement ball end mill for use in milling machines and machining centers that accept a 3/8 inch collet or toolholder. Verify spindle speed, feed rate, and material compatibility before installation.

Installation Notes

A licensed machinist or qualified CNC operator should install and set this end mill. Confirm the toolholder collet or end mill holder is clean and undamaged before seating the shank. Power down and lock out the machine spindle before changing tooling. Follow the machine manufacturer guidelines and applicable shop safety procedures for tool runout verification and cutting parameter setup.
