Frequently Asked Questions

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.
