牙輪鉆頭是使用較廣泛的一種鉆井鉆頭。牙輪鉆頭工作時切削齒交替接觸井底，破巖扭矩小，切削齒與井底接觸面積小，比壓高，易于吃入地層；工作刃總長度大，因而相對減少磨損。牙輪鉆頭能夠適應從軟到堅硬的多種地層。
按牙輪數量可分為單牙輪鉆頭、三牙輪鉆頭和組裝多牙輪鉆頭。按切削材質可分為鋼齒（銑齒）和鑲齒牙輪鉆頭。
牙輪鉆頭作為一種鉆削巖層的工具已被廣泛應用，鉆頭性能的顯著改進直接降低鉆井成本，尤其是近十年進步較快。使用壽命和鉆速兩個性能指標，它們較終確定鉆頭影響鉆井成本的程度。提高鉆頭的機械鉆速和使用壽命是降低鉆井成本的有效途徑，有資料證實，鉆速的改進比鉆頭壽命的改進對降低鉆井成本的影響更大，其中鉆頭切削結構的改進是提高鉆頭的機械鉆速較直接的方法。很長時間以來，人們對切削結構的改進主要集中于主切削齒結構，例如在硬質合金齒結構方面，人們先后發明了楔形齒、勺形齒、偏**勺形齒、等磨損齒等等。人們逐漸認識到保徑結構也對鉆頭機械鉆速和壽命有較大影響，尤其在大斜度井和水平井應用的鉆頭要求具有合理的保徑結構，許多新型保徑結構被研究開發出來并應用到牙輪鉆頭上取得了良好的效果。
