Tungsten carbide insert bits for hard formations

Hard, well-compacted rocks such as: hard silica limestones, quarzite streaks, pyrite ores, petryfied, hematite ores, magnetite ores, chromium ores, phosphorite ores, granites.   A large number of short inserts with great top angle, closely spaced, ensure optimum condition for drilling in hard formation. Minimum cone axis offset against centre line of the bit prevents the inserts from breakage.A large number of heel row inserts maintain full gage longer.

We will never sacrifice quality for short term benefits.                               ---Reet XS
