A bit combining dome buttons, wear protection, water channels, inner cutting buttons and overcut for high effectiveness in demanding drilling conditions.
The combination of dome buttons, wear protection, water channels, inner cutting buttons and overcut makes this bit highly effective in more demanding drilling conditions. It is designed for projects with long drilling runs in medium-dense formations, hard clay and medium-hardness rock; water channels reduce the risk of overheating and clogging at the cutting face.
