Greenfield Putnam 94288 is a 1/4-inch diameter end mill made from high-speed steel with a long 3/8-inch shank and four flutes. The extended shank offers increased reach for milling deeper pockets or contours where a standard tool can’t reach. This HSS end mill, identified by part number 94288, is designed for general metalworking milling tasks that benefit from a four-flute cutter.
