Frequently Asked Questions About PCD/PCBN Cutting Tools
Polycrystalline Diamond (PCD) is a synthetic superhard material made by sintering diamond grains together under high pressure and high temperature (HPHT) with a metallic catalyst binder. PCD is known for its exceptional hardness, wear resistance, and thermal conductivity, making it ideal for cutting non-ferrous metals, composites, wood, and abrasive materials.
Polycrystalline Cubic Boron Nitride (PCBN) is the second hardest material known after diamond. It is synthesized from cubic boron nitride grains under high pressure and temperature. PCBN is primarily used for machining ferrous materials (steel, cast iron) where diamond would react chemically, offering excellent wear resistance and high-temperature stability.
PCD (diamond-based) is best for non-ferrous materials like aluminum, copper, brass, wood, plastics, and composites. PCBN (boron nitride-based) is designed for ferrous materials such as hardened steel, cast iron, and high-speed steel. The key difference lies in chemical compatibility β diamond reacts with iron at high temperatures, while PCBN does not.
Our products are manufactured in Zhengzhou, Henan Province β the largest superhard materials production base in China. This region accounts for the majority of the world’s synthetic diamond and CBN output. Our parent company, SINO QTECH INDUSTRIES CO., LIMITED, is headquartered in Hong Kong and manages global sales and logistics.
Our team has over 20 years of experience in the superhard materials and cutting tool industry, dating back to 2005. We have built long-standing partnerships with leading manufacturers and testing laboratories in China’s superhard materials hub.
We offer a comprehensive range of superhard cutting tools: PCD Cutting Tools & Blanks, PCD Inserts, PCBN Cutting Tools & Blanks, PCBN Inserts, PDC Drill Bits, PDC Picks, Synthetic Diamond Grits & Powders, and CBN Abrasives. We also provide custom cutting tool design and manufacturing services.
PCD tool blanks range from D6mm to D36mm+ in various thicknesses. PCBN grades include BN500, BN600, BN800, BN900, and BN950 for different hardness levels. PCD inserts are available in ISO standard geometries (TPGH, CCGT, VBMT, etc.). Custom sizes and grades are available upon request.
Yes, we provide custom cutting tool design and manufacturing based on your specific application requirements. Share your workpiece material, machining parameters, and desired outcomes, and our engineering team will recommend or design the optimal tool geometry and grade.
Yes, we provide free samples of standard products for evaluation and testing. Customers typically cover shipping costs. For custom tools, we can produce prototype samples for trial before full-scale production.
Our MOQ is flexible. For standard products, orders start from 10 pieces. For custom tools, we typically require a minimum of 5-20 pieces depending on complexity. Contact us for specific requirements β we’re happy to work with both small and large orders.
Standard products: 3-7 working days after payment confirmation. Custom orders: 7-20 working days depending on complexity and quantity. Urgent orders can be expedited β contact us for specific timelines.
We accept T/T (bank transfer), PayPal, Western Union, and Alibaba Trade Assurance. For large orders, we typically require 30% deposit and 70% before shipment. Flexible payment terms are available for long-term partners.
We ship via express courier (DHL, FedEx, UPS) for small orders, air freight for medium orders, and sea freight for bulk shipments. Our parent company’s Hong Kong logistics team handles all shipping arrangements with real-time tracking. FOB, CIF, and DDP terms are available.
Our manufacturing facilities operate under ISO 9001:2015 quality management system. Material composition certificates and test reports are available for all products. We can also arrange third-party inspection upon request.
Every product undergoes a multi-step quality process: (1) Raw material inspection with full traceability, (2) HPHT sintering parameter monitoring, (3) Dimensional inspection using precision instruments, (4) In-house cutting performance tests, (5) Final visual and packaging inspection before shipment.
Yes, we operate an in-house PDC performance testing laboratory in Zhengzhou. Our lab is equipped with cutting test machines, hardness testers, metallographic microscopes, and wear analysis equipment. We use test data to optimize tool designs and verify quality for every batch.
Yes, we provide lifetime technical support including: product selection recommendations, cutting parameter optimization (speed, feed, depth of cut), tool life improvement consulting, and troubleshooting. Our engineering team is available via email, WhatsApp, and video calls.
We stand behind the quality of our products. If a product fails due to manufacturing defects, we will replace or refund it. For custom tools, we work with customers to resolve any performance issues through design adjustments or material selection changes.
