Bits and drilling systems for civil construction, mining and construction

Self-drilling Bits or 4-ring bit with TC buttons

Krham manufactures self-drilling bits (or 4-wing bit with TC buttons) up to 200mm in diameter that can be produced for any type of drilling machines and in any thread.

Because this is a piece that should have a single use, its level of hardness is not the same as other systems that require micropilling as 3-wing bits, casing crowns or bits. Still, Krham can produce them taking into account the needs of each specific case, including tungsten carbide buttons to perform their tasks as quickly and efficiently as possible.
