Allan,
Hmmm, I must not have clicked the submit reply button on my answer this morning. Been driving all day from Seattle and now down in Yreka, Ca for the night, so, I'll keep this short, very tired.
Actually those bits appear to be for heavy duty operations using a water based drill system. Perhaps for boring deep holes into rock for demolition charges in roadway construction, etc.
The bits shown in the link that I posted will last forever if only used in Lava.
One could also rent a roto hammer and bits from Home Depot in Hilo...
E ho'a'o no i pau kuhihewa.
