A cutting arrangement (10) includes a pick holder (12) having a bore (14) containing a sleeve (16) within which a shank (18) of a pick (20) is located. The pick (20) and the sleeve (16) each have heads (22; 24). The head (24) of the sleeve (16) has an outer abutting surface (26) and an inner abutting surface (30). The outer abutting surface (26) abuts an abutting surface (28) of the head (22) of the pick (20). The inner abutting surface (30) abuts an abutting surface (32) of the pick holder (12). The abutting surface (28) of the head (22) of the pick (20) has an outwardly curved formation (28.1) which abuts an inwardly curved formation (26.1) on the outer abutting surface (26) of the sleeve (16). The inner abutting surface (30) on the head (24) of the sleeve (16) has an outwardly curved formation (30.1). The abutting surface (32) of the pick holder (12) has an inwardly curved formation (32.1). The inwardly and outwardly curved formations (30.1; 32.1) abut one another.
A cutting arrangement including a pick holder having a bore containing a sleeve within which a shank of a pick is located, with the pick and the sleeve each having heads, the head of the sleeve having an outer abutting surface and an inner abutting surface, the outer abutting surface abuts an abutting surface of the head of the pick, and the inner abutting surface abuts an abutting surface of the pick holder, with the abutting surface of the head of the pick having an outwardly curved formation which abuts an inwardly curved formation on the outer abutting surface of the sleeve.
A cutting arrangement including a pick holder having a bore containing a sleeve within which a shank of a pick is located, with the pick and the sleeve each having heads, the head of the sleeve having an outer abutting surface and an inner abutting surface, the outer abutting surface abuts an abutting surface of the head of the pick holder, with the inner abutting surface of the head of the sleeve having an outwardly curved formation interposed between inwardly curved formations and the abutting surface of the pick holder having a inwardly curved formation interposed between outwardly curved formations, with the respective inwardly and outwardly curved formations abutting one another.
A cutting arrangement including a pick and a pick holder, the pick having a head with a shank extending there he head having an abutting surface which abuts an abutting surface of the pick holder, the abutting surface of the head having an outwardly curved formation which abuts an inwardly curved formation on the abutting surface of the pick holder.
A sleeve including an outer abutting surface for abutting a head of a pick, and an inner abutting surface for abutting a pick holder, the outer abutting surface having an inwardly curved formation for abutting an outwardly curved formation on the head of the pick.
A sleeve including an outer abutting surface for abutting a head of a pick and an inner abutting surface for abutting a pick holder, the inner abutting surface having an outwardly curved formation, interposed between inwardly curved formations, for abutting an inwardy curved formation, interposed between outwardly curved formations, on the pick holder.
A pick holder including an abutting surface with an inwardly curved formation interposed between outwardly curved formations, for abutting an outwardly curved formation on a sleeve or a pick.
