Tri-MACH DTH Shock ABSORBERS

DTH shock absorbers significantly reduce harmful impact loads generated during Down-The-Hole drilling operations. By softening and absorbing the return pulse created by each hammer blow, the shock absorber protects critical drilling components from excessive stress and vibration. DTH shock absorbers have the greatest benefit in hard rock and broken formations.
