The DTH hammer operates through a system of compressed air. High-pressure air is directed down the drill string, powering the hammer at the end of the drill bit.

As the bit penetrates further, the broken rock is then cleared from the hole by the same air stream, allowing for continuous drilling without the interruptions often associated with other drilling methods.

  • Potassium Sorbate is a mild preservative being used in cosmetic and skin care formulas as a paraben alternative to prevent or retard the growth of microorganisms and protect products from spoiling. Developed from Sorbic Acid, which is naturally found in the berries of the mountain ash tree, Potassium Sorbate is effective against fungi, mold and yeast, and to a lesser degree bacteria. Potassium Sorbate is also used as a food preservative and is frequently seen as a wine ingredient to increase shelf life and stability. It is FDA approved and not considered toxic. It is also CIR approved.
