42R SERIES port tools are identical to the 42P Series cutters except that they are manufactured with an integral carbide tipped reamer pilot (rather than a plain pilot) which sizes the minor diameter of the Class 2 thread specification.
Modifications of standard tools are readily available. Special cutters, manufactured to customer's specifications, are given prompt attention.
