High Quality: Long service life and High durability. 200 times more than the small wheel durability.Processing all kinds of metal(including all sorts of hardened steel) and non-metal (such as marble, jade bone). Material: Tungsten Carbide (10 times higher than the durability of high speed steel cutter) No Dust Pollution: High production efficiency. In most cases, it can replace a small grinding wheel, the processing efficiency higher than small wheel stalk nearly ten times without dust pollution. Easy to Use: Convenient control, Safe and reliable.Good machining quality,high degree of finish,can work out the high accuracy of various shapes mold cavity.Convenient control,using simple,safe and reliable,reduce labor intensity,improve the working environment. Widely Application: For processing of metallic and Non-metallic surfaces. Suit for materials such as wood, plastic, soft metal like aluminum.Great for craft, airfix modelling, home, repairs etc.A variety of mechanical parts chamfer,round and groove processing.
