Made of HHS steel with H7 accuracy.

The Sloting Plus reamers are specifically intended for use on any aluminum or plastic parts.

Advantages over conical reamers:

          precision - have the same diametrical measurment from end to end

          acccuracy - the finished hole is perfectly tailored through the whole length and will never be conical

          security - the shaft will always be perfectly adjusted to the hole throughout its length
