As regards its importance it is second only to the lathe machines.Holes were drilled by the Egyptians in 1200 B.C. Actually, diamond tool generally used to grind away material on a micro level, it can last up 20 times as long as a bare tungsten carbide tool, but it also cost much higher than any other options. Whether the job is well completion, re-entry, oil, gas, water, or mining, drill bit manufacturers have risen to the challenge to meet the needs of the drilling industry. Uses: When traditional drills can’t perform massive works, an impact driver can do it with much ease.
