Model 63-B stabilizers and welded blade stabilizers lead our complete line of blasthole stabilizers. The model 63-B is the original roller stabilizer specially designed for blasthole drilling. Positioned directly behind the bit, the model 63-B stabilizer centralizes and stabilizes the bit, providing smooth rotation, reduced vibration, and more effective drilling. Air is circulated through the rollers, cooling and cleaning the hardened bearing surfaces, maximizing wear life. The result is better penetration rates, high productivity, and lower overall cost.
Our welded blade stabilizers are manufactured with a body of alloy steel and can be supplied with straight or spiral ribs. Ribs are steel wear bars welded to the body and covered with a hard metal overlay or tungsten carbide inserts. The welded blade stabilizers are extremely effective in wet or dry, soft or medium formations, and have been designed for increased life and reduced operating costs.
