Kirjes Heavy-Duty Flex Shaft

With a reinforced wire core and heavy-duty bearings, this is a robust flex shaft. It comes with two chucks – a 3/8" drill chuck for general use, and a smaller 5/16" keyless chuck that improves visibility and clearance when using carving burrs or small sanding drums.

The large-diameter contoured handle is comfortable to grip for extended periods. The shaft has a reach of about 51", will run at speeds of up to 10,000 rpm (cannot operate in reverse) and has a 1/4" shank that mounts in most drills.
