Product Description
The 46–100 mm cold-pressed carbide button family spans medium and large rock-hole gauges for mine development, quarry benches, and civil excavation. That range crosses several drill and connection classes, so the chosen diameter must be tied to a specific rig and rod system. Frame the use through the mining and exploration application archive and evaluate wear through the abrasive formation archive. This is a product family, not evidence that one physical body can cover every gauge from 1.81 to 3.94 inches.
The source confirms cold-pressed carbide buttons and a 46–100 mm mining-rock range. An alloy-steel body with fixed inserts is therefore appropriate, but connection, face profile, skirt, button count, and flushing pattern are not supplied. Those details normally change as diameter increases. A 46 mm bit for a light top hammer should not be assumed to share the impact class or connection of a 100 mm tool. Request a size-specific drawing that identifies the thread or shank, gauge protection, porting, and insert arrangement before release.
Operate within 1,000–3,000 lbf/in of actual diameter and 25–60 RPM. Calculate total load separately for each selected gauge and verify that the drill can provide stable impact without overloading the connection. Hard and abrasive rock suit the button mechanism, while fractured ground may require reduced input. Flow is blank because the range includes unverified port and rod combinations. The limitation is the absence of a diameter-to-connection matrix. Rock and mineral context can be reviewed through the U.S. Geological Survey.
