A reamer is turned by means of a wrench, or it can be set up in a vise and the work turned around it. The reamer should be turned slowly until the operator is sure that it is straight in the hole, and then should be turned with a steady, firm pressure until it has been put all the way through the hole. The leading end is subjected to the greatest amount of wear because it does the greatest amount of work. If, therefore, only this leading end is put through, the hole will not be of a uniform diameter throughout.

Taper Reamers.-Taper reamers are used to finish tapered holes for the insertion of tapered pins or other tapered parts.

Machine Reamers.-The machine reamer is usually inserted in a chuck or a socket mounted in the spindle of a portable electric

or air motor. Machine reamers are also made either solid or adjustable, and each of these groups may be subdivided into straight or taper reamers.

Care of Reamers.-As stated previously, a reamer must never be turned in any way except to the right, or clockwise, even when removing it from the work. Do not use too much feed (pressure) because the reamer may hit a hard spot in the metal and break. This is especially likely with small reamers. When using a lubricant on the reamer, it is good practice to remove the tool from the work frequently and wipe away the chips which stick to the flutes. If the chips should clog, they would be likely to damage the finish on the walls of the hole. Remember that an adjustable reamer must be kept absolutely clean to do accurate work. Handle reamers carefully; if they are dropped or thrown against other tools, their sharp edges will be nicked and dulled. If the hole is too small, enlarge it with a drill before reaming it.
