H42R SERIES port tools are manufactured with an integral reamer pilot (rather than a plain pilot) which sizes the minor diameter of the Class 2 thread specification. They profile the internal O-ring boss and port contour for the S.A.E. straight thread tube fitting (identical to MS 16142). One operation forms the complete port accurately to military specifications. This high speed steel, short, sturdy cutter performs well in both ferrous and non-ferrous materials and may be used in a wide range of machinery and equipment (such as drill presses, lighter equipment, older machines, etc.), which are not suitable for carbide’s high rigidity and high horsepower requirements.

Precision ground between centers to insure concentricity. All cutting edges are form relieved and all flutes cut the entire form to provide balance, distribution of chip load, maximum tool life between grinds, and ease of sharpening.

Modifications of standard tools are readily available. Special cutters, manufactured to customer’s specifications, are given prompt attention.
