From APS Germany comes the FHA50, an extension which accepts larger polishing cones associated with the FLEX FS 140 and APS HEX cones.
Incorporated rotary attachment plugs directly into the machine like an OEM piece, and the opposing end of the extension adapter utilizes a sliding sleeve which allows the 'HEX' end of the cone to be inserted and locked into place for use. No unwanted spindle spinning under load, just mechanical lock while using a larger cone for polishing tight spaces. Perfectly balance, lightweight aluminum construction, OEM fit and finish, knurled grip for quick-fitting cones.
Pictured but NOT included is an example of the HEX cone attached to the FHA50 for reference. Those cones may be found and added to cart HERE
