The best Tungsten carbide, combined with accurate bore hole tolerance, to achieve best brazing connection and high durability.
1. Types: We can supply kinds of ROUND SHANK BITS and HOLDERS for different rotary piling rigs. Types as below: B47K-17H, B47K-19H, B47K-20H, B47K-22H.
2. Uses: These machine parts are widely used on foundation drilling, piling, Trenching, Tunneling, Road planing. They can suit for all kinds of drilling machines, Products can also be Custom-made.
3. Material: High Manganese Alloy steel Body, made of 42CrMo, heat treatment with 40-44HRC hardness, forged and Anti-rust treatment, has high toughness and wearable character.
4.Raw Material: Tungsten carbide is produced from wolfram carbide and cobalt. Wolfram carbide is one of the hardest known materials, but is also brittle. Combining it with weak cobalt a material is generated which is very hard and resistant to wear, and which can withstand extreme impact loads.
