Custom 3‑Blade Drag PDC Bit

This three‑blade drag PDC bit is engineered for harsh and abrasive geological conditions. Different from ordinary three‑blade drag bits, its main cutting area is equipped with 1308 enhanced PDC cutters . The cutting structure delivers improved impact resistance and deeper rock‑cutting penetration, bringing outstanding rate of penetration (ROP) during drilling operations.

The side and lower sections of the bit are fully arranged with 1305 PDC gauge cutters for complete gauge protection . The gauge area is fully covered to prevent premature gauge wear and hole diameter reduction. While maintaining fast drilling speed, it greatly reduces matrix abrasion, extends overall bit service life, minimizes tripping times for bit replacement, and cuts down total drilling cost.

Specifications & Customization

Standard available sizes: 3 inch, 4 inch, 4.5 inch, 5 inch, 5.5 inch, 6 inch, 6.5 inch, 7 inch, 8 inch, 9 inch, 10 inch, 12 inch. Custom non‑standard sizes are fully supported. Thread connections including NC, REG, IF, FH and other well‑drilling standard threads can be customized to match various drill rigs and drill pipes.

Suitable Formations

Optimized for heavy‑sand complex formations . It performs reliably in gritstone, muddy sandstone, siltstone and other highly abrasive rock layers. Stable drilling performance can also be achieved in loose sand beds and alternating soft‑hard strata, with low risk of cutter chipping and premature wear‑out.

Application Scenarios & Projects

Widely applied in potable water wells, agricultural irrigation wells, shallow geological exploration, geotechnical investigation, shallow geothermal wells, foundation pilot drilling for construction projects, and shallow mine drilling. Ideal for field mobile drilling jobs with medium & small‑size drill rigs.

Popular Overseas Markets

This three‑blade drag PDC bit gains huge popularity in Philippines, Nigeria, Romania, Kenya, Ghana, Peru and other regions. It is heavily purchased for local water‑well construction, small‑scale mining and infrastructure drilling projects, and is a high‑repeat‑order core product for overseas wholesalers and drilling contractors.

As a direct PDC bit manufacturer, we accept bulk OEM orders. Tooth layout can be adjusted according to clients’ formation data to deliver bits tailored for local working conditions.
