Key Benefits
Popular Sizes & Specifications:
PDC bits for water well drilling are available in a wide range of diameters (commonly 3″ up to 17½″) to suit various well sizes
All sizes utilize standard API Reg connections for compatibility with drill rods. The number of blades (cutting wings) and the blade profile are tailored to the bit size and formation hardness – smaller bits usually have fewer blades and a flatter profile for soft formations, while larger bits have more blades and often a curved or serrated profile for stability in harder rock.
Rig Compatibility
TTM’s tricone bits are compatible with a wide range of rotary blasthole drill rigs, including Epiroc DM45, DML, Pit Viper 231, Pit Viper 275, as well as Sandvik D45KS, D50KS and other leading models in the industry.
