Corehead - core bit
Flexible design, optimized coring performance

Tercel provides all types of core heads that can be fitted with PDC, Dual, Impregnated cutting structures, steel or matrix bodies. The CoreHeads are based on the same design approach as conventional fixed cutter drill bits and can be further customized according to specific applications. Such applications as lithology, formation hardness, abrasiveness, and core barrel adaptation requirements.

The flexibility and wide range of design features that focus on the cutting structure, inner and outer reinforcement and hydraulic settings are ideal for drillers looking to find the right CoreHead for their specific application.

Blade count, spiraling severity and cutting structure (PDC, Impregnated, Dual, TSP or natural diamond) as well as CoreHead profile and internal design can all be customized accordingly to help customers optimize both drilling performance and the quality of recovered core samples.
