Product Description
This ballistic button-bit family covers 43–51 mm gauges and source pairings that include 38R25 and 45R32 for mining rock drills. The range is suitable for development holes and construction rock work when the chosen diameter and connection match the installed rod string. Use the mining and exploration application archive and compare rock conditions with the hard formation archive. R25 and R32 are separate interfaces; the family must not be treated as a dual-thread physical bit.
The source identifies a threaded ballistic carbide structure with 43–51 mm gauges and the 38R25/45R32 references. The safest interpretation is a product family containing distinct R25 and R32 models. An alloy-steel threaded body carries fixed ballistic buttons, but face profile, count, gauge layout, skirt, and flushing ports are not stated. The numeric pairings may describe nominal diameter and connection, yet a drawing is still required because source naming alone does not establish shoulder dimensions or the complete available matrix.
Operate within 1,000–3,000 lbf/in of actual diameter and 25–60 RPM. Hard and abrasive formations suit ballistic carbide contacts, while fractured ground may require lower loading to avoid edge impact. Keep each thread family in separate inventory locations to prevent a visually similar but incompatible substitution. Set flushing from the chosen rod and face ports; no flow value can be supported by the filename. The limitation is that only two representative size-thread pairings are named within a wider 43–51 mm range. Thread and drilling-system context can be checked through the IADC.
