Abstract
A guide pad for a cutting tool is formed with at least one sliding surface, which is convexly curved in a plane perpendicular to a longitudinal axis of the guide pad. Each sliding surface includes two convexly curved sliding sub-surfaces separated by a fluid conveying formation having a longitudinal extension in a direction in parallel to the longitudinal axis. The fluid conveying formation is planar or has a convexly curved shape in a direction perpendicular to the longitudinal axis having a larger radius of curvature than the radius of the sliding surface.
Claims13
A guide pad for a cutting tool, comprising at least one sliding surface convexly curved as viewed in a plane perpendicular to a longitudinal axis of the guide pad, each at least one sliding surface including two convexly curved sliding sub-surfaces separated by a fluid conveying formation (20) having a longitudinal extension in a direction in parallel to the longitudinal axis, wherein the fluid conveying formation is planar or has a convexly curved shape as viewed in a plane perpendicular to the longitudinal axis and having a larger radius of curvature than a radius of the sliding surface.
The guide pad according to claim 13, wherein the fluid conveying formation has a width, in a direction in parallel to the median plane and perpendicular to the longitudinal axis, that is smaller than half of the guide pad width.
A cutter head for a drilling tool, the cutter head comprising a guide pad, the guide pad including at least one sliding surface convexly curved as viewed in a plane perpendicular to a longitudinal axis of the guide pad, each at least one sliding surface including two convexly curved sliding sub-surfaces separated by a fluid conveying formation having a longitudinal extension in a direction in parallel to the longitudinal axis, wherein the fluid conveying formation is planar or has a convexly curved shape as viewed in a plane perpendicular to the longitudinal axis and has a larger radius of curvature than a radius of the sliding surface.
