HOW DO THEY WORK?
Negative, cobalt tipped designed for maximum hardness and resistance to heat and wear and ultimate precision.
Low rake angle grinding enables the tip to bore through all materials with a filing action rather than a cutting action. This enables you to drill through brick, steel, stone, marble and many more products. The heat generated will not affect the tip because the high tech bonding allows the bit to withstand drilling temperatures up to 1,100 degrees Celsius.
