This drilling frame uses ER 16 collets, five of which are included which will accommodate 1/8″, 3/16″, ¼”, 5/16″, and 3/8″.  The spindle can be shortened or extended in the bearings by loosening the shaft collars and sliding it to a new position in order to allow for reaching into tighter spots.  The aluminum bearing block mounts into a typical tool quick change tool holder and features non-contact, sealed bearings that deliver a freer running and cooler operation.   Also included is an eccentric cutter of Fred Armbruster’s design with a 60 degree carbide cutter (other angles available).  The cutting frame accepts 1/8″ diameter cutters.  The set also has one 3/16″ fly cutter that is useful as an internal cutting frame and for thread cutting.

The individual components are also available and priced upon application.
