How do I choose the most suitable pick for different rock hardness?
Selection depends on the Protodyakonov scale (f value) of the rock.
For Soft Rock (f<6): We recommend our standard grade (YG11C carbide) for cost-efficiency.
For Hard Rock (f≥8): We use premium large-grain carbide (YG13C/YG15C) with a reinforced body to withstand high impact.
Please provide your rock type (e.g., Coal, Limestone, Sandstone) and we will provide a customized recommendation.
Are your picks compatible with major roadheader brands like Sany, Sandvik, or Joy Global?
Yes. Our products are manufactured according to standard ISO and OEM specifications. We offer all standard shank sizes, such as Dia30/38mm, Dia35/42mm, and Dia38/46mm. As long as you provide the model number or the shank diameter, we can guarantee 100% compatibility with your existing cutting head and bit holders.
Can you manufacture tools based on our specific drawings or samples?
Absolutely. We offer comprehensive OEM/ODM services. Our engineering team can optimize tool geometry and carbide grades based on your specific geological conditions (e.g., granite, limestone, or mixed ground).
What is your standard lead time for bulk orders?
For standard specifications, we maintain a safety stock for immediate shipping. Custom orders typically take 10-20 days depending on the complexity and quantity.
Are you a direct manufacturer or a trading company?
We are a professional manufacturer specializing in TBM (Tunnel Boring Machine) cutters and mining tools. With our own advanced CNC machining facility and specialized heat treatment lines, we maintain full control over product quality and production schedules.
