IADCTricone Bit classification system

4 character code, first 3characters are numbers, the last is a letter

1st number isthe series. 1 to 3 represent a milled tooth tri cones, 4 – 8represent TCI tri cones. The higher the series number the hardermore abrasive the rock formation is.

2nd number isthe relative degree of hardness within a series. The number rangesfrom 1 – 4, the higher the number the harder theformation

3rd numberrepresents bearing design and gauge protection.

1. Openbearing
2. Roller bearingair cooled
3. Open bearinggauge protected
4. Sealed rollerbearing
5. Sealed rollerbearing gauge protected
6. Sealed frictionbearing
7. Sealed frictionbearing gauge protected

4th character isa letter and describes optional features. There are 16 alphabeticcharacter’s each representing the tricones most significantfeature.
