Provided are a guide pad having sufficient strength and a gun drill having the guide pad. A guide pad includes: a first surface; a second surface that is a flat surface located at a position opposed to the first surface; and a third surface that connects the first surface and the second surface to each other. When viewed along a rotational center axis, the first surface is a circular-arc-shaped surface, and when a point at which a virtual line passing through a circular-arc center of the first surface and perpendicular to the second surface and the second surface cross each other is assumed as a first point and a point at which a central axis of the through hole and the second surface cross each other is assumed as a second point, the first point is located at a position closer to the third surface than the second point.

A machining station especially arranged to carry out deep drill and milling operations is disclosed. The machining station now proposed presents a specific structural arrangement, enables the incorporation, contrary to already existing stations, of an axis dedicated to deep drilling, favoring the use of deep drill tools under ideal conditions, without size restriction. Accordingly, the station is comprised of an operating base, on which there lays an operating module and an arrangement module. This new arrangement for the machining station is therefore more versatile and adaptable to the specificities programmed for each part to be machined.
