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.They are sized by a number sequence (for example, a No.4 reamer would use No.4 taper pins).
Read MoreDeep hole machining is an industry segment for the production of holes in long parts. Typically, this is defined by the ratio of part length to hole diameter. Generally speaking, this is anything in excess of 20:1 ratio up to 100:1. Longer ratios are achievable with consideration of tolerance and final part requirements.
