Product Description
The R32 threaded button-bit series lists 45, 48, 51, 57, and 64 mm gauges for hydraulic rock drills working in mine development, bench preparation, and civil excavation. A common thread family can simplify tooling, but every diameter still needs to match the required hole and available impact energy. Place the selection within the construction drilling application archive and compare the rock with the medium formation archive. The series is not intended for soft ground where the hole cannot support impact loading.
The filename identifies an R32 connection and five nominal diameters, plus a threaded tapered-button description. The structure is represented as an alloy-steel threaded body carrying fixed carbide buttons. It does not establish one universal face pattern across the full 45–64 mm range. Larger gauges may require different button counts, flushing holes, or skirt proportions, and none of those layouts is verified by the source name. Confirm shoulder condition, thread form, gauge protection, and port geometry for the exact diameter rather than scaling details from the product photograph.
Use 1,000–3,000 lbf/in of bit diameter and 25–60 RPM. Calculate total load from the selected gauge and begin conservatively when the hydraulic drill is newly matched to a diameter. Medium and hard formations are appropriate planning classes; abrasive rock warrants frequent thread, face, and gauge inspection. Flow is left open because the source does not specify rod bore or flushing pressure. The stated limitation is that R32 fit is known while face configuration varies by size. Thread-system background can be reviewed through the IADC.
