Diamond Drill Bit Lip Shape:

Full Round		Higher diamond content in the bit face.higher penetration rate.and suitable for drilling hard rocks.
Semi-round		Even diamond distribution in the bit face,suitable for drilling medium-hard and hard rocks.or a little broken and loose formations.
Fiat		For impregnated diamond bit oniy,suitable for drilling hard abrasive rocks.
Bottom Discharge Design		Suitable for drilling sedimentary or metamorphic formations containing more powder mineraiw with high core recovery percentage,and no excessive core washout.
Stepped		Suitable for dr drilling medium-hard,broken or interbedded formations, hoie deviation can be prevented.
Tapered		Suitable for drilling soft and medium-hard formations with high penetration rate.
Serrated Profile		Suitable for drilling hard dense formations with high penetration rate.
Staggered Concentric Profile		Suitabie for drilling hard dense formations with high penetration rate under low bit weight.
GearWheel		Suitabie for drilling hard dense formations with high penetration rate.
