Scour protection for drill bits

PARZYNSKI JR DAVID B / CONGDON THOMAS M

A tool bit (200) includes a handle portion (202) defining an axis of rotation (218) and a working portion (208) including a plane (228) perpendicular to the axis of rotation (218), defining a perimeter in the plane (228) and surrounding the handle portion (202). The working portion (208) defines a bottom pocket surface (262) that defines a pair of side pockets (264, 264a), and a front pocket (265) that forms a "U-shape" with the pair of side pockets (264, 264a).

一种刀头(200)包括柄部部分(202)和工作部分(208)，该柄部部分(202)限定旋转轴线(218)，该工作部分(208)包括垂直于该旋转轴线(218)的平面(228)，在该平面(228)中限定周边并且包围该柄部部分(202)。该工作部分(208)限定底部凹穴表面(262)，该底部凹穴表面(262)限定一对侧凹穴(264、264a)，以及与该对侧凹穴(264、264a)形成“U形”的前凹穴(265)。
