It can be used as a hand tool or mounted in a radial drill for a more permanent and positive installation. Works well in C N C controlled machines. The tool is adjustable from 22 to 54 mm (7/8” to 2 1/8”) from the face of the sheet to the back side of the inner groove. Larger sizes on request. TUBE-END FACERS For facing ends of tubes in heat exchangers and condens- ers. It has one replaceable tool bit and a set of rotating pilot bushes. Fitted with an adjustable thrust collar the unit incorporates a depth gauge which accurately controls the amount of tube projection. An important safety feature is the left-hand threaded adjustment of this part to prevent accidental self feeding of the cutter. Available for tubes from 5/8” to 1 1/4” (15.8 mm to 31.75 mm) O.D.
