This SAE Recommended Practice provides a systematic method for the identification of single diameter and taper reamers. It is intended to assist in the cataloging and supplying of these tools.

1. NOTE 1— Caution must be taken when assigning codes for designators to prevent specifying reamers that cannot be physically or economically manufactured.

2. NOTE 2— The Code Number coming from the manufacturer MUST reflect the actual tool construction.

3. NOTE 3— In particular without limitation, SAE disclaims all responsibility for the accuracy or completeness of information contained within this report if the standards of this report are retrieved, combined, or used in connection with any software.
