Specifications and Product Details:

TRICONE BITS USE FOR FOUNDATION DRILLING TOOLS, THEY ARE MAINLY USE FOR CORE BARRELS, FOR VERY HARD GROUND. MAINLY USE FOR 8 1/2” AND 12 1/4” TRICONE BITS.

WE WILL SELECT VERY GOOD TRICONE BITS AND CUT THEM INTO THREE PIECES AND USE THEM ON THE CORE BARRES. WE USE VERY GOOD IADC 537 AND IADC637 etc for hard rocks . save more money.
