Product Overview

This custom multi-stage detachable pagoda-type PDC hole opener features a standard 3 1/2 REG thread , professionally designed for staged reaming and hole enlargement in water well drilling, geological exploration, and mining drilling projects. Adopting a unique four-stage layered enlargement structure, the drill bit realizes gradual hole diameter expansion, with a progressive size range from 132mm to 171mm, 219mm, and finally 254mm, meeting diverse caliber drilling and reaming construction requirements.
Different from integral reaming drill bits, this PDC reaming bit adopts a fully detachable layered design. Each stage of the reaming module can be independently disassembled, replaced, and maintained separately. Users can flexibly match and use single-stage or multi-stage combinations according to actual formation conditions and on-site drilling needs, effectively avoiding overall bit scrapping caused by partial wear, greatly reducing drilling costs and improving construction flexibility.
Manufactured with high-strength alloy steel and premium PDC cutters, the drill bit boasts high hardness, strong wear resistance and impact resistance. The optimized cutter layout ensures stable rock-breaking performance and high reaming efficiency, suitable for various soft and medium-hard formations. As a professional customized PDC drilling tool, it delivers stable performance and long service life for complex on-site drilling and reaming operations.

Key Advantages

Modular detachable structure realizes partial replacement and maintenance, lowering operation and replacement costs. Gradual multi-stage reaming reduces drilling resistance, protects the well wall, and improves reaming accuracy and flatness. Custom structural design adapts to complex formation drilling demands, with outstanding versatility and cost performance. Our factory supports personalized customization of PDC hole openers and various PDC drill bits of different specifications to meet diverse drilling project needs.
