Cat designs tricone bits to lower drilling costs

Cat tricone drill bits have been designed for the most severe rotary blasthole applications but at the same time are cost effective for a wide range of drilling needs.

The new bit line from Caterpillar includes six diameters ranging from 171mm (6-3/4in) to 311mm (12-1/4in). Their carbide shapes and cutting face arrangements are optimised for high wear-resistance and improved rock fragmentation and the aggressive, long-lasting cutting structure is said to deliver a superior rate of penetration.

Caterpillar's heat treatment technology and advanced air-cooled bearing design yields longer bit life and results in lower overall drilling costs. Cat bits also use innovative technology to prevent cuttings and unbroken rock ridges from inflicting severe wear on the cone. The result is improved working life. Also, the gauge row design improves resistance to diameter shrinkage.
