Dental Bur Number Decoder

Every bur built to the international standard carries a number that describes it completely: material, shank, shape, grit, and head diameter. This tool reads that number for you.

Enter whatever is printed on the box or in the invoice line: the full ISO number, the short shape/diameter form, a supplier item number, or a Taft product ref. You get the instrument's full specification and, where we stock that shape, a link to it.

For the reference tables behind this tool, see our bur shape and number chart and the guide to bur shanks.

Works with a US carbide number like 557, a full ISO number, a short form like 199/014, a supplier item number like 199-014M, a European code like 850, or a product ref like TR-11.
