Milled Tooth
- For use in soft alluvial formations, clays and soft rock
- 500-4000PSI Compressive Strength formation
- Rock formation, talk, shale, clay, mudstone, calcite and gypsum.
- Teeth are machined directly from hardened steel with tungsten.
- Hardfacing being applied to the trailing edge to maintain the shape of the cutter.
TCI (Tungsten Carbide Insert) Type 4
- Medium Rock
3000-15000PSI Compressive Strength formations. - Rock formation: calcite, limestone, sandstone, slates, marbles.
- Pointed TCI teeth have aggressive conical shaped points and create an aggressive penetration rate.
TCI (Tungsten Carbide Insert) Type 5
- Medium rock – hard rock
12000-25000PSI Compressive Strength formations - Rock formation: granite, marble, dolomite, schist, gneiss
- TCI teeth have less extensions, with gage protection mark extend cutter life.
- Thread Connections as per API Standards.
TCI (Tungsten Carbide Insert) Type 7
- Hard Rock
25000-45000PSI compressive strength formations . - Rock formations: quartz, basalt, taconite and quartzite.
- TCI Teeth are domed to prevent breakage when drilling in very hard rock. Cutters offer gage protection to extend cuter life
- Thread Connections as per API Standards.
