Product Description
This 38 mm ball-tooth button bit is intended for short production holes, face drilling, and exploratory work where the rock is competent enough to accept repeated impact. Its compact gauge suits handheld or light mechanized drilling, subject to confirmation of the rod interface. The operating context should be checked against the mining and exploration application archive and the medium formation archive. It is not a casing-advancement tool and should not be selected to stabilize loose overburden.
The source filename identifies a carbide-tipped ball-tooth structure at 38 mm and also carries a “32” reference. Because that reference could describe a series or source model rather than an insert count, this record does not present it as thirty-two verified buttons. The practical construction is an alloy-steel bit body with fixed carbide inserts that transfer impact into multiple contact points. Exact shank geometry, flushing-hole count, gauge-button layout, and heat-treatment condition must be confirmed from a drawing or physical sample before the bit is matched to a drill string.
Begin within 1,000–3,000 lbf/in of bit diameter and 25–60 RPM, then adjust only after impact delivery, return quality, and gauge wear are stable. Medium and hard rock are the primary formation classes; abrasive ground requires closer inspection of peripheral inserts and more attention to recutting. No universal flow value is assigned because compressor capacity, hole depth, and rod passage govern flushing. The limitation is explicit: diameter and cutter family are known, but connection and port geometry are not. General classification context is available from the IADC.
