Standard Sample Pin = Pin Number X Taper Length
Non-Standard Sample Pin = Large Diameter X Taper Length
Standard Taper 1/4″ to 12

When ordering sizes other than those included in the above list, specify the length and diameter at the large end.
Standard reamers are available for pins given above the line.
Pins nos. 11 (size .806), 12 (size 10.32), 13 (size 1.241), and 14 (size 1.523) are special sizes — hence their lengths are special.
