CFA bit for coal-seam sampling
Continuous flight auger bits for taking samples from coal seams.
Overview
The catalogue shows a set of these bits: hollow barrel-type heads and toothed auger heads, both used to bring coal-seam material to the surface for sampling.
The catalogue has no size table for them, so we quote each bit to match your rod diameter and connection.
