Cutter Specifications

Milled Tooth

Alluvial formations, clays, soft rock

(500-3,000 PSI) compressive strength formations

Formation types: Sandstone, shale, mudstone, clays, gravels and conglomerate

Teeth are milled directly from the hard cone steel and tungsten hardfacing applied on the trailing edge to maintain sharpness of the blade. TCI gage row MT cutters available on special order

Type 7 (IADC)

Medium - hard rock

(12,000 - 25,000 PSI) compressive strength rock

Formation types: Granite, marble, and dolomite

TCI teeth have moderate extensions

Gage area has all dome type cutters to maximize cutter gage life

Type 5 (IADC)

Medium rock

(6,000 - 15,000 PSI) compressive strength rock

Formation types: Limestone, sandstone, and shale

TCI teeth are aggressive conical shaped for aggressive penetration rates in medium type rock

Type 8 (IADC)

Hard rock

(25,000 - 45,000 PSI) compressive strength rock

Formation types: Quartz, basalt, and quartzite

TCI teeth are all hemispherical shape, providing a longer cutter life in extremely hard rock
