Import Diamond High-Knife — Buy in Bulk from Supplier in China

The Diamond High-knife from Dongguan Haiying Cutting Tool Co., Ltd. is a precision cutting tool crafted from natural diamond with a hardness of HV9000-10000, making it one of the hardest materials available for industrial applications. The tool maintains a stable cutting edge over extended use, ensuring a long service life, and its edge arc remains gap-free even under 400x magnification. This level of precision is critical for achieving ultra-smooth surface finishes, with roughness values as low as Ra 0.01-0.025 µm.

Designed for machining non-ferrous metals and softer materials, this tool excels in processing gold, silver, aluminium (and its alloys), zinc (and its alloys), and acrylic (PMMA). The natural diamond composition provides superior wear resistance compared to synthetic alternatives, reducing the need for frequent replacements. Standard diamond cutting tools in the industry often use polycrystalline or single-crystal diamond, but natural diamond offers enhanced durability for high-precision tasks.

These tools are widely adopted in industries such as jewellery making, electronics, and optical component manufacturing, where fine tolerances and flawless finishes are non-negotiable. Buyers typically source these tools for applications requiring micromachining or intricate detailing. The supplier’s specifications include multiple size options, such as D dhl 60 3650, 90 3650, 120 3650, 150 3650, 90 4650, and 120 4650, catering to diverse machining needs.

Dongguan Haiying Cutting Tool Co., Ltd. is based in Tiankeng Village, Hengli Town, Dongguan, Guangdong Province, China. The company specialises in manufacturing precision cutting tools, with a focus on diamond-based solutions for high-precision applications. Its address and operational base in Guangdong, a hub for advanced manufacturing, underscore its capability to serve both domestic and international markets with technical expertise.

The supplier operates under a harbor trust tier, though its current response rate is 0.00 due to no recorded interactions. The listing highlights its expertise in natural diamond tools, a niche that demands rigorous quality control and deep material knowledge. While the profile does not disclose additional details such as certifications, client lists, or production scale, the focus on natural diamond tools suggests a commitment to high-end machining solutions.
