摘要: A gage surface cutting element (22, 30, 50, 70, 100, 120) for a cutter (20) in roller cone drill bit (10) has generally cylindrical body (32, 52, 72, 102, 122) formed of hard and wear-resistant material. The end (34, 54, 74, 104, 124) the conical (38, 58, 78, 108, 128) substantially perpendicular to longitudinal axis 122). plurality parallel shallow elongated grooves (40-42, 60-63, 80-82, 110-112, 130-132) are 128), strips an ultra material (44-46, 64-67, 84-86, 114-116, 134-136) is disposed grooves. result that alternating surfaces can be oriented at 0°, 90°, or any angle between with respect rotational direction (20).
