Matt Ring Tube Sizer-USA Sizes
With this tool you can enlarge the finger hole of wax ring models with speed and accuracy. Hardwood mandrel is machined to incorporate a steel cutting blade that extends from the handle to the tapered tip. Slide this reamer through the hole of a wax ring or ring tube and gently rotate clockwise. As the blade turns, it scrapes the inner wall enlarging the ring to the size that is clearly marked on the mandrel and leaves a smooth, and uniform finish on the ring.
Because the ring mandrel is slightly tapered, you may have to reverse the side you are cutting to even out the inside of the wax. Additional flatting can be achieved with a file, or use the new Matt Ring Reamer 121.02887 to make a perfectly flat inside cut.
