As a professional center drill bits manufacturer, ZXGLW uses selected imported materials and undergoes precise production steps to provide you with high-quality products. This drill bit can process a variety of materials and is suitable for a variety of CNC machine tools. We can also provide you with preferential factory prices and timely delivery.
1. High-quality materials
Imported tungsten steel high-quality raw materials, sub-micron carbide grains bring high heat resistance, high hardness, high wear resistance, hardness up to 58 degrees.
2. Unique process
The cutting edge is polished and coated, and the nanoparticles are covered in the coating on the surface of the knife to reduce friction and make it more wear-resistant. The two-edge design reduces cutting wear, and the knife head is sharp and durable.
3. Usage method
It is necessary to make points before drilling, and drilling requires a separate drill bit. Spraying is the best method for cold cutting of steel. Appropriately reducing the cutting speed and feed speed can extend the life of the tool.
4. Scope of application
Center drill bits are suitable for processing stainless steel, mold steel and other materials, suitable for CNC machining centers, engraving machines, precision engraving machines and other CNC machine tools.
5. Packaging features
Adopt exquisite plastic packaging boxes, universal pie shape, clamping and fastening as chamfered round pie, widely used.
As a manufacturer's direct sale, there is no middleman link, and the price is affordable. The product packaging is exquisite and atmospheric, and the quantity is accurate and reliable. Easy to use, allowing you to enjoy high-quality products and services with high cost performance.
