Crown Typesare made so the impregnated diamond section is sintered onto the steel body of the barrel. This gives the diamond section more strength. The advantages are the bit can withstand more steel reinforcement and angle drilling without damage. Segmental Typesare made so the impregnated diamond segments ate braized onto the steel barrel. The advantage of this method is the barrel is easily retipped which helps reduce the cost of drilling
