Tri-Cone™ Bits

For Rotary & Motor Applications

Century Products offers a full line of made in the USA Tri-Cone ™ Bits in both Tungsten Carbide Inserts (TCI) and Milled Tooth cutting structures.  There are a variety of sizes and configurations in both the TCI and Milled Tooth cutting structures which allow our products to be tailored to specific drilling conditions.

Soft Formation TCI Bits
For shales, sandstones, limestones and dolomites

These Tri-Cone ™ Bits are designed for maximum penetration rates.  Bit tracking is virtually eliminated by combining a large cone offset, sharp chisel-shaped inserts and non-uniform tooth spacing.  Shirttail protection along with carbide leg protection increases bit life for HDD applications.

Medium to Hard Formation TCI Bits
For medium-hard shales, limestones, sandstones and dolomites

These Tri-Cone ™ Bits have moderately sharp conical or chisel inserts with a shorter extension.  An increased insert count helps reduce breakage when drilling in harder formations.  Full bottom hole coverage and non-uniform insert spacing results in smooth drilling at high penetration rates.

Hard Formation TCI Bits
For hard sandstones, granites, dolomites, quartzite and pyrites

These Tri-Cone ™ Bits are designed to withstand high loads and drill abrasive conditions where rock is broken under high compressive point loads, with little scraping and gouging.  Therefore, the cutting elements tend to be small, exhibit shorter protrusion and are more densely packed, which prevents the high compressive loads from breaking the tooth before it breaks the rock.
