A strong spring steel envelope which compresses rings in position on the piston enabling the assembly to be inserted easily into the bore without the risk of damage.

A power drill will drive this three legged tool via its integral flexible shaft to remove heat glaze & carbon deposits from cylinder bores up to 180mm diameter. The tension of the medium grade cutting stones can be adjusted to obtain the desired finish.

Specially designed spring-loaded pliers with tapered holding jaws make the job of fitting and removing piston rings that much easier and safer.
