These reamers are especially designed for the reaming of structural steel plate commonly found in truck frames, rail cars, bridges and pressure vessels. For use only to enlarge previously formed or drilled holes.
Chucking Reamers are reamers held in a chuck and usually being stationary while the workpiece revolves. It can be used on lathes, drill presses, and screw machines.
Construction/Bridge Reamers are designed for lining up holes in structural steel fabrication bridgework, shop construction, automotive maintenance, and railroad car manufacture.
Hand reamers are designed with a longer taper to compensate for the difficulty of starting a hole by hand power alone. Hand expansion reamers are designed to enlarge holes by a few thousandths by turning an adjusting screw on the end of the reamer.
Jobber Reamer is a hand or machine reamer with flutes and taper shanks used to bring holes to a more exact size or improve the finish of a hole. It may be used either in a machine or when provided with a suitable holder as a hand tool.
A shell reamer is a type of rotary cutting tool used in metalworking, designed to enlarge the size of a previously formed hole by a small amount but with a high degree of accuracy to leave smooth sides and these reamers are designed for reaming bearing and other similar items. They are fluted almost their whole length.
A precision tapered reamer is used to make a tapered hole to later receive a tapered pin. A taper pin is a self-tightening device due to the shallow angle of the taper.
