Bullet teeth for bore piling drill buckets augers, core barrel in foundation engineering

For drill bits, there are bullet teeth, flat soil teeth, pilot bits, roller bits. For bullet teeth, they are usually for hard stratum situation. Above pictures are all drill tools of Drillmaster ( UNIMATE and UNIDRILL are both brands of DRILLMASTER). So, what kind of bullet teeth should be chosed for different bore pile drilling core barrels, kinds of drill buckets, drill augers? Since there are many different shapes and different sizes of bullet teeth, also called tungsten carbide bullet teeth. So, how to choose the suitable kind of bullet teeth for your bore pile drilling buckets, rock augers, core barrels or centrifugal drill buckets?

Firstly, this depends on the bore pile need to drill, or, we can say, decided by the geologic condition of the project.

Secondly, the OD (size) of the drill bucket or augers used. Experienced manufacturers can recommend the suitable bullet teeth / drill teeth / drill bit directly according to the customers' description for the construction site and the drill tools they use.
