Features Fast Chipping: This set really achieves a good finish, comfortable to use, fast chipping speed, high hardness, good machining quality, no clogging and increased productivity. Safe and Reliable: Considering the safety of the operator, this set is made of hard tungsten steel, which is stable and less error-prone, making the operator more assured of his own safety. Packed in a plastic storage box for safe storage and protection. The service life of these solid rotating burrs is 10 times that of high-speed steel and 200 times that of grinding wheels. Simple Operation: The kit is easy to master and use, just operate under the normal process to get good results, and it is also very friendly to novices. Different shapes can meet your needs, easy to grasp and use, safe and reliable. Reduced Manual Labor: The kit greatly reduces the heavy manual labor, reducing production costs and allowing users to work more vigorously in an easier mode. Ideal for your DIY woodworking, carving, carving and polishing. Applicable scenarios: The groove lines of these carbide rotary drills cross, making them more suitable for materials with relatively low density, mainly used for grooving narrow and deep metal materials such as copper, iron, aluminum, alloys, etc. below medium hardness And the outer surface is polished. It can also be used for milling of non-metallic materials such as plastic and wood.
