Dynabrade 53533 Cone or Plug Straight-Line Triple Extension Grinder 1 hp, 18,000 RPM, Rear Exhaust, 3/8″-24 Spindle Thread

Includes 3/8″-24 Male Threaded Adapter (53610) Extension Grinders allow operator to extend into work pieces and reach lengthy distances. Extension length of 8-3/8 allows longer reach than competitive models! Extensions are constructed of steel for maximum durability. Designed for minimal vibration. Extensions do not spin during tool use, so continuous tightening is not needed (as with some one-piece shaft-type extensions). Tools can also be fitted with optional Buffing Pads, optional collets and inserts, plus optional Cone/Plug Wheels. (Note: Speed of tool must not exceed maximum operating speed of accessory.)
