CFA bits
Lead bits for continuous flight augers: a toothed bit for rock, a flat-tooth bit with centre pilot for soil, and bits for coal-seam sampling. Quoted to match your CFA rod.

The bit is the bottom section of a CFA string and does the cutting; the flights above it carry the spoil to the surface. The catalogue shows three types, each pictured below.
The catalogue gives no separate size tables for the bits. They are made to fit the rod, and our CFA rods are listed from Φ300 to Φ1000 (auger diameter 280–980 mm). Send us the rod type, diameter and connection and we will quote the matching bit.
