RC50 Hammer button Bits 5 3/8" For the Reverse Circulation Drilling
Reverse Circulation Button Bits RC Bits 5 3/8" for RC Drilling
Reverse Circulation Bits
Our bits for Reverse Circulation (RC) drilling are produced according the highest quality control standards. Our concave bits are available with a patented Trubbnos buttons for longer life and enhanced rate of penetration (ROP) and improved sample quality. Our RC drilling bits are also made from premium grade tungsten carbide.
Choose from a variety of bits, shanks and buttons depending on your needs.
1. Two shapes of buttons including spherical and trubbnos
2. Several different bit shank styles to choose from
3. PCD button bits on demand
Your choice of bit will depend upon the type of RC hammer you are using.
Use our RC Configurator to make sure you get the product you need.
Precision hardened keys are lighter weight and facilitate short shank lengths. Shank design gives highest Piston-to-Bit weight ratio—maximizing button face energy. Airflow channel design and control minimizes Bit face plugging and eliminates unwanted pressurization of surrounding formations.
Roschen manufacture various drilling equipment needs from outstanding performance solution (equivalent to Atlas Copco COP Gold and MISSION series DTH hammer & button bit), to economical solution (equivalent to Atlas Copco DHD and SD series DTH hammer & button bit), to low working air pressure drilling solution (equivalent to Atlas Copco CIR series DTH hammer & button bit), to Overburden drilling solution(equivalent to Atlas copco Symmetrix and Odex casing system), to RC drilling solution(equivalent to Atlas Copco RC45, RC50 and RE004, RE542, RE543, RE054 RC DTH hammer & button bit).
