Specials - Many of the above standards can be adjusted to a special by altering the dimensions, adding a hole, lengthening the part length etc. Specific physical information or a print is required to develop a special. Refer to the ANSI B94.13 specification and list for more information on the specific alterations and tolerances required to define the special part.
Bur Blank Identification:
The Bur Blank identification is a developed descriptor using the following details:
Example: BSA-6
·BS - Bur Blank
·A - Type (Cylindrical)
·6 - Size (.640" +/-.005" Diameter X 1.000" +/-.010" Long)
