圓切刀片（玻璃、玻璃管、LD、石英以及平板玻璃等）硬脆材料超高耐磨型的切割、切斷、壓痕用）。刃口堅硬耐磨，鋒利（在顯微鏡下觀看，刃口鋒利一致，無缺口。用手拿刀片在玻璃管或石英管上輕輕就能劃出痕跡，不會出現打滑現象）。選用的鉆石鋼具有極高的耐磨耗性能，相應一般鎢鋼，具有3~6倍以上的使用壽命。（可生產任意外徑、內徑、厚度、切割角度等尺寸公差要求的制品，耐用性、鋒利性無以倫比）。采用德國鎢鋼素材和日本富士設備精密成型研磨加工。 高品質，超低價位。國內用戶，如有需要，可以免費3片樣品測試。各種角度都可以。您可以直接與國外原裝進口產品，對比品質。 round cutting blades ( glass, glass pipe, LD, quartz, sheet glass etc.) are used to cut hard and brittle material ultra-high wear-resistant materials. The blade is hard and wear-resistant and sharp（in the microscopic view, the blade is sharp and without gaps. It will be easy to leave traces when you draw on the glass or quartz tube and not slip）Optional diamond steel has a very high anti-abrasion properties, corresponding general tungsten steel, it has 3 or 6 times life.( Can produce any products with requirements of  diameter, inner diameter, thickness, dimensional tolerances and with an unparalleled durability and sharpness) we use Tungsten steel material of Germany and equipment in Fuji of Japanese to preciously grinding and molding. High quality and low price. We can provide 3 free samples for test if the domestic customer needs. It can be any angle. You can directly compare the quality of our products with that of original ones imported from foreign countries.
