Product Description
The 45 mm nine-button threaded bit is intended for mine development, rock excavation, and compact jumbo holes where a distributed carbide face is preferred. Its 1.77-inch gauge and stated nine-button arrangement provide a defined starting point for matching a hole plan. Review the work under the mining and exploration application archive and compare the formation with the medium formation archive. The bit is not identified as a core bit, casing shoe, or tool for unsupported loose material.
The source confirms nine buttons, 45 mm, a threaded body, and tungsten-carbide construction. It does not state how many buttons protect the gauge, the face profile, or the thread series. The record therefore describes an alloy-steel threaded body with nine fixed carbide contacts without assigning R32, T38, or another interface. Flush-hole count, skirt length, and button shape also remain open. A thread drawing is essential because a correct 45 mm gauge can still be mechanically incompatible with the available rods and shank adapter.
Use 1,000–3,000 lbf/in of diameter and 25–60 RPM. Medium and hard formations are suitable; abrasive rock requires regular checks of the nine contacts and the gauge surface. Begin with balanced collaring so one portion of the face does not accept excessive impact. Record the verified thread beside the SKU so replacements cannot be selected by gauge alone. Flow is blank because the source gives no rod bore or port area. The explicit limitation is the unnamed thread system and unverified face distribution. Drilling terminology can be reviewed through the IADC.
