Drill Chucks - tools and machinery equipment
For machines with removeable, interchangeable arbors: To find an arbor/chuck combination that works for a given machine, first identify the type of spindle on the machine. (For instance, a milling machine might have an R8 spindle; a drill press might have a #3 Morse Taper (MT) spindle; a lathe tailstock might hold 2MT tooling.)
