Machine - Shell Reamers High Speed Steel Shell Reamers are multi-fluted, end cutting tools used to enlarge previously formed holes to a precise diameter with a smoother finish. They are used with with a special shell reamer arbor which is tapered to fit the holes in the reamer.
Seco’s new generation Precimaster Plus modular, indexable-head reaming system provides accuracy and part processing versatility.Through a selection of various reamer shanks and heads, users can accommodate a variety of hole sizes and workpiece materials with fewer required tools.
Straight reamer A straight reamer is used to make only a minor enlargement to a hole. The entry end of the reamer will have a slight taper, the length of which will depend on its type. This produces a self centering action as it enters the raw hole. The larger proportion of the length will be of a constant diameter.
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. They may be driven into the tapered hole such that removal can only be done with a hammer and punch.
A tapered reamer may be used for cleaning burrs from a drilled hole, or to enlarge a hole. The body of the tool tapers to a point. This type of reamer consists of a body which, typically, is up to 1/2 inch in diameter, with a rod cross piece at the large end acting to form a handle.
