Value Collection 320-3765 Ball End Mill 7/8 in 4 Flute Hss

Product Description

The VALUE COLLECTION 320-3765 is a single-end ball end mill designed for contour milling, profiling, and 3D surface work in metalworking and machining applications. Built from high speed steel with a bright, uncoated finish, this tool measures 7/8 inch in diameter with a 1-7/8 inch length of cut and a 4-1/8 inch overall length. The 4-flute, right-hand spiral configuration supports efficient chip evacuation and smooth cutting in a wide range of ferrous and non-ferrous materials. The standard shank diameter matches the mill diameter at 7/8 inch, making it compatible with common collet and end mill holder setups found on vertical mills and CNC machining centers.

This ball end mill is suited for job shops, tool rooms, and production environments where operators need a reliable HSS ball nose tool for finishing passes, slotting, and contour work. It is a standard-length, single-end design intended for general-purpose milling operations on manual knee mills or CNC equipment. Machinists and tool room operators working with mild steel, aluminum, cast iron, and similar materials are the primary installers and users of this tool.

Installation Notes

Installation is performed by machinists using appropriate collet chucks or end mill holders rated for the 7/8 inch shank diameter. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Torque the retention mechanism to the toolholder manufacturer specification. Verify runout with a dial indicator before taking cuts, and follow shop safety protocols and applicable OSHA machine guarding requirements during setup.
