一种新的金刚石切削结构，通常被称为金刚石增强嵌件，已被开发用于旋转冲击钻井。几年时间致力于这一进步的开发和测试。其结果是将多层金刚石涂层粘结到碳化钨基底上。多层涂层大大提高了抗冲击性。与硬质合金相比，金刚石强化刀片有几个优点。它们增加了钻头寿命，提供了更好的井眼质量，减少了下井时间，降低了钻井成本。

A NEW DIAMOND CUTTING STRUCTURE, COMMONLY CALLED A DIAMOND ENHANCED INSERT, HAS BEEN DEVELOPED FOR ROTARY PERCUSSION DRILLING. SEVERAL YEARS WERE DEVOTED TO THE DEVELOPMENT AND TESTING OF THIS ADVANCEMENT. THE RESULT IS A MULTI-LAYERED DIAMOND COATING BONDED TO A TUNGSTEN CARBIDE SUBSTRATE. THE MULTI-LAYERED COATING GREATLY IMPROVES IMPACT RESISTANCE. DIAMOND ENHANCED INSERTS HAVE SEVERAL ADVANTAGES OVER CARBIDE. THEY INCREASE BIT LIFE, PROVIDE BETTER HOLE QUALITY, REDUCE DOWN TIME, AND DECREASE DRILLING COSTS.
