Advantages
1. high quality carbide ensures high quality and performance.
2. Carbide grade options for long life in challenging applications.
3. Face designs to maximize penetration rate and tool life.
4. Optimized flushing designs to aid in cuttings removal and reduce
wear
Face shape Features
Concave Face
1. Capable of drilling straighter holes in medium to hard rock
which is broken or less consolidated
2. Offers high penetration rate in the above stated rock conditions
3. Has excellent air flushing characteristics
4. Predominant face style for majority of drilling conditions
Flat Face
1. Have a superior performance in hard, abrasive and broken rock
conditions
2.They however have a slower penetration rate in comparison to a
concave face bit
Convex Face
1. This face has been designed to offer high penetration rate in
soft rock such as shale, limestone etc
2.They are recognized for having excellent capability for drilling
into moderately consolidated rock conditions
