This is a 57mm diameter button bit with R32 thread and 9 tungsten carbide buttons, designated as Part No. 3057R3209. The R32 thread is a standard rope thread interface used in medium to heavy duty rock drilling. The bit body is of normal design with a flat face profile, suited for drifting and tunneling applications where controlled breakage and moderate penetration rates are required.
The cutting structure uses nine inserts of tungsten carbide in spherical, ballistic, or conical geometries. Spherical buttons offers superior wear resistance and are standard for hard, abrasive rock; ballistic and conical alternatives suit softer or more fractured formations where versatility is needed. The carbide grade and braze joint integrity determine overall bit life, though the supplier does not specify carbide sub-grade or hardness values in this listing.
Typical buyers include mining contractors, tunneling specialists, quarry operators, and construction firms running hydraulic or pneumatic drill rigs with R32 shank adapters. The 57mm diameter sits within the common range for face drilling in development headings and small-scale production holes. Buyers should confirm exact button geometry, flushing hole configuration, and shank compatibility before ordering, as these affect cuttings evacuation and drilling efficiency.

Before placing an order, verify that Maxdrill Rock Tools can supply the exact button geometry matched to your rock conditions. Request a material certificate for the tungsten carbide inserts, including cobalt content and hardness. Confirm thread gauge compliance with your existing R32 shank adapters, and ask for a dimensional drawing showing flushing hole arrangement. The zero response rate in supplier metrics means proactive follow-up by email or phone is essential to secure documentation and avoid specification misunderstandings.
Logistics from Guiyang, Guizhou Province involve inland transport to a Chinese seaport, typically Shanghai, Shenzhen, or Guangzhou, adding 3-7 days to overall lead time. Confirm Incoterms with the supplier, whether EXW Guiyang or FOB port, as this determines freight and customs clearance responsibilities. Payment terms for harbor-tier suppliers often require advance payment or documentary credit; negotiate letter of credit or 30 percent deposit with balance against documents if cash flow permits. Standard export packing should be specified in the purchase order to prevent transit damage to cutting structures.
On arrival, inspect each bit for visible thread damage, button integrity, and correct part number marking. Mount a sample bit and check for excessive vibration or runout, which indicates concentricity issues. Request mill test certificates for body steel and carbide grade, and cross-check hardness values against agreed specifications. For critical tunneling projects, retain an independent inspection agency to witness pre-shipment tests or conduct destination port checks on first orders.
