Import Drag Bit — Buy in wholesale FOB from Supplier in India

Drag bits from Prime Rigs Ltd are designed for drilling in soft formations such as sand, clay, and light shale, commonly used in water well, environmental, and geothermal applications. Each bit features tungsten carbide inserts that are 3/16 inch thick, hand-soldered with nickel silver rod, and mounted on blades forged from 4140 heat-treated tool steel. The forging process ensures consistent grain structure, and the blades are milled to precise tolerances to seat inserts securely. The nose is fully welded with 7018 high-tensile rod for impact resistance, and relief angles behind each insert are hand-ground to reduce friction and improve cutting efficiency.

These bits are not suited for coarse gravel or hard rock, where impaction and abrasion would rapidly degrade the cutting structure. The standard carbide insert size and placement align with industry norms for soft formation drilling, where controlled chip removal and low torque demand are priorities. The use of 4140 steel forgings, rather than cast or machined blanks, provides superior toughness under cyclic loading. Hand-soldering each insert allows for localized heat control, minimizing metallurgical distortion compared to automated processes.

Buyers typically source these bits for municipal water well contractors, environmental drilling firms, and exploration teams operating in alluvial or sedimentary basins. The bits are supplied loose, without packaging beyond protective coating, and are shipped in bulk to reduce freight cost. Minimum order quantities are not stated; buyers should confirm unit volumes and lead times directly with the supplier. Trade terms are typically FOB Hyderabad, with payment by T/T or L/C at sight.
