Cutting tool assembly

A cutting tool assembly (10), comprising a body portion (12) and at least one cutting portion (14), the at least one cutting portion (14) comprising a clamping portion (16), an insert retaining member (18), and a securing member (22);

• the clamping portion (16) comprising:
• a first base jaw (26) having an upper side (28) constituting a first clamping surface;
• a first clamping jaw (30) having an upper side and a lower side (32), the lower side (32) constituting a second clamping surface, the upper side (28) of the first base jaw (26) being substantially parallel to the lower side (32) of the first clamping jaw (30), the first base jaw (26) and the first clamping jaw (30) having a gap (34) between them for receiving the insert retaining member (18) therein, the gap having a front end and a rear end, the gap defining a front-to-rear direction;
• a slot (36) extending rearwardly away from the rear end of the gap (34) in the front-to-rear direction, the slot terminating in an aperture (38);
• a first location surface (44), located at the rear end of the gap, for fixing the location of the insert retaining member (18);
• the insert retaining member (18) comprising:
• a second base jaw (48) having a front end and a rear end, and a lower side (54) constituting a first clamping abutment surface and a second clamping jaw (50) having an upper side (56) constituting a second clamping abutment surface, the second base jaw (48) and the second clamping jaw (50) defining therebetween an insert pocket (52);
• and
• a second location surface (60) configured to abut the first location surface (44) for precisely locating the insert retaining member (18) in the gap (34);
• and
• a securing portion (58) comprising an elongated portion of the insert retaining member (18) extending from adjacent the rear end of the second base jaw (48) in the front-to-rear direction away from the front end of the second base jaw, the securing portion being shaped and sized to pass through the slot (36) and be received in the aperture, wherein
• the securing member (22) is removably attachable to the elongated portion of the insert retaining member for securing the insert retaining member (18) in the gap (34) between the first clamping jaw (30) and the first base jaw (26) of the clamping portion (16), with the securing member (22) being located in the aperture (38).

A cutting tool assembly having a cutting portion comprising a clamping portion, an insert retaining member, and a securing member, wherein:

• the clamping portion comprises a first clamping jaw and a first base jaw defining a gap therebetween, the gap having a front end shaped and sized to receive the insert retaining member, the gap also having a rear end terminating in a slot which extends in a direction away from the front end and leads to an aperture;
• the insert retaining member comprises a second clamping jaw and a second base jaw defining therebetween an insert pocket, the second base jaw having a front end proximate to an opening of the insert pocket, and a rear end, the insert retaining member further comprising an elongated securing portion extending from adjacent the rear end of the second base jaw in a direction away from the front end of the second base jaw, the elongated securing portion being shaped and sized to pass through the slot and be received in the aperture,
• and wherein the assembly is adjustable between:
• a disassembled position in which the insert retaining member and the securing member are separated from the clamping portion, and
• an assembled position in which the insert retaining member is positioned in the gap with the elongated securing portion extending at least partially into the aperture, and the securing member at least partially occupies the aperture and is attached to the elongated securing portion of the insert retaining member to thereby secure the insert retaining member in the gap.
