New Drill Bits Last 3 to 5 Times Longer
Sandvik has announced the release of a
new range of drill bits for mining exploration, production and grade control applications that are claimed to deliver substantial increases in bit life, particularly in
challenging ground conditions. Its new
Diamond Enhanced (DE) Carbide range of
drill bits offer far superior wear- and abrasion-resistant characteristics in difficult
mining conditions, according to the company, which noted that the properties of DE
Carbide bits have resulted in increases in
bit life by a factor of three to five times—
greatly reducing the need for multiple bit
changes when drilling deep holes in abrasive formations. The new bits have been
successfully trialed in a range of drilling
applications, including DTH (down-thehole), TH (top-hammer) and RC (reversecirculation) drilling.
