H49R SERIES port tools profile the A.N.D. 10050 or MS 33649 contour. This cutter features the economical, integral reamer pilot construction, which makes it desirable for short runs and prototype work. The reamer pilot sizes the minor diameter per the applicable thread specification.
Made from high steel, its short, sturdy construction performs well in highly abrasive materials, and in both ferrous and non-ferrous materials. Like the H49 series, this port tool may be used in a wide range of machinery and equipment not suitable for carbide's high rigidity and high horse power requirements.
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. A slight positive axial rake provides shear action, preventing buildup on the cutting edges and reducing cutting pressures.
Modifications of standard tools are readily available. Special cutters, manufactured to customer's specifications, are given prompt attention.

Explanation of pilot sizes for all Craig Port Contour cutters. On reamer pilot tools, the reamer diameter approximately the mean diameter. This hole, in order to meet applicable Mil. Spec. should be sized according to the mean of the min-max tolerance on the minor diameter of the specifications. The common practice of using a standard drill without reaming and/or referring to tap drill charts, cannot be followed since, in most cases, there are no standard drills which produce hole sizes that will meet the Mil. Spec. tolerance on minor diameters.
