The FX series is designed for drilling soft formations, with rock compressive strength ranging from 0 to 12,000 psi.

The FX302 blasthole bits are the latest advancement in cutting structure design. This bit features the most aggressive cutting structure with larger diameter inserts and insert projections. The wider cutter profile allows for more inserts.
The FX Series is our air bearing series used for softer ground types in replacement of the traditional steel tooth bit. Great in coal and other softer formations.
