Abstract
Perfections in milling heads with reversible tip blades, comprising a circular body formed with a circular series of slots, an elongate stop block interchangeable in each of the slots, formed at one end with a seat that matches a part of the contour of a reversible tip for said head, and gripping means with each of said grooves for fastening in the latter its respective abutment blocks and tips, characterized each of said reversible stop blocks with respect to its slot and is formed at its opposite end with a further seat that differs from the aforementioned first seat, whereby a tip correspondingly different from said first tip is operatively accommodated in its inverse position in the slot.
