Eccentric-hole-PDC-Bit2 Eccentric-hole-PDC-Bit

Eccentric-hole PDC Bit

Eccentric-Hole PDC Bit is a key product developed with Genway’s patented invention technology. Designed for through-the-rod screen or gas drainage pipe installation in soft coal seams, it helps solve common problems such as borehole collapse, pipe installation failure, and blockage during gas drainage drilling.

Hole-Cleaning-Bit Hole-Cleaning-Bit2

Hole Cleaning Bit

The Hole Cleaning PDC Bit is used for borehole cleaning, re-cutting, and restoring hole condition after drilling. With reinforced cutting elements arranged on the outer section, it helps remove residual cuttings, smooth the borehole wall, and clear restricted or narrowed sections.

Retrieval-Bit Retrieval-Bit2

Retrieval Bit

Retrieval Bit is designed for borehole recovery and downhole tool retrieval operations. Its specialized retrieval profile helps capture broken tools, dropped components, or debris inside the borehole, while the PDC cutting structure assists with stabilization, clearance, and continued hole cleaning.

PDC-Reamer1 PDC-Reamer-overhead1

PDC Reamer

The PDC Reamer is designed for enlarging pre-drilled pilot holes in mining, gas drainage, ventilation, cable, and utility-hole applications. By reaming from a smaller pilot hole to the required final diameter, it helps improve borehole straightness, drilling stability, and hole-forming quality.

Frequently Asked Questions

Full-Blade-Roof-Bolt-Bits
Genway is a specialized manufacturer of PDC mining and drilling tools with 28 years of manufacturing experience. Genway We focus on PDC bits, roof bolt bits, core bits, non-core bits, cutting picks, coal picks, and customized drilling solutions for coal mining, tunneling, roadway support, gas drainage, geological exploration, and construction applications. Compared with general tool suppliers, Genway combines product design, precision machining, PDC cutter application, brazing technology, quality control, and field application support to provide more reliable solutions for demanding working conditions.
Genway was built on early innovation in applying PDC diamond technology to coal drilling tools. Its founder was among the pioneering inventors who introduced PDC into coal mining drill bits, helping improve tool life and drilling efficiency beyond conventional carbide tools. With diamond-enhanced cutting performance, Genway PDC tools offer stronger wear resistance, longer service life, and more stable operation in hard and abrasive formations. This helps reduce replacement frequency, minimize downtime, and lower overall operating costs.
Our quality assurance process includes raw material inspection, PDC cutter selection, precision machining checks, brazing quality control, dimensional inspection, cutter bonding verification, appearance inspection, and final product testing before shipment. These processes help ensure stable drilling performance, strong cutter retention, reliable wear resistance, and consistent product quality in demanding mining and construction environments.
The right tool depends on your formation, equipment, hole size, drilling method, and performance target. Genway can recommend suitable PDC bits or cutting picks based on formation hardness, abrasiveness, coal-rock ratio, machine power, drilling depth, required hole diameter, connection type, water flushing conditions, and field problems such as fast wear, low drilling speed, cutter breakage, or frequent replacement.
Genway provides technical support before and after product delivery to help customers improve field performance. Our team can assist with tool selection, working condition analysis, product matching, usage feedback, and improvement suggestions. For customized or application-specific products, Genway can also review field results and optimize cutter layout, body structure, waterway design, or material selection for future batches.
To provide an accurate quotation and product recommendation, international clients are encouraged to share key working-condition details. Useful information includes product type, diameter, connection type, quantity, drilling or cutting equipment, formation type, rock hardness, abrasiveness, working depth, current tool problems, expected service life, and any drawings, photos, or samples. The more field information provided, the more accurately Genway can recommend or customize the right solution.
