Abstract: A cutter holder has a body, a collet fastening unit, a collet, a cutter, multiple concentricity adjusting units, and multiple straightness adjusting units. The collet fastening unit is assembled on the body. The collet is assembled on the collet fastening unit. The cutter is inserted into the collet. The body has a fastening flange which has multiple concentricity adjusting holes. The multiple concentricity adjusting units are respectively screwed in the multiple concentricity adjusting holes and abut against the collet fastening unit to correct the error of concentricity between the cutter and the body. The collet fastening unit has an assembling flange which has multiple straightness adjusting holes. The multiple straightness adjusting units are respectively screwed in the multiple straightness adjusting holes and abut against the body to correct the error of straightness between the body and the cutter.

Abstract: A cutter holder has a holding segment and a flange. The holding segment has a triangular cross section, a first end, a second end, and a central hole. The second end is opposite the first end. The central hole is axially defined in the first end of the holding segment. The flange is disk-shaped, is coaxially formed on the second end of the holding segment, and has a periphery, an identifying hole, and a connecting hole. The identifying hole is radially defined in the periphery of the flange. The connecting hole is axially defined through the flange, communicates with the central hole in the holding segment, and has an inner thread formed in the connecting hole.

Abstract: A cutter holder includes a body, a collet, a cutter, and a fastening cap. The cutter is inserted into the collet. The collet is assembled on the body with the cutter. The fastening cap is mounted on the body, and the cutter protrudes from the fastening cap. The body has a fastening portion; the collet has an annular groove. The fastening portion has a fastening portion end face. The annular groove has a first face. The fastening portion end face and the first face are separated by a distance. By means of confining the distance between the fastening portion end face and the first face, a contact area between the body and the collet is increased to enhance the clamping force. Accordingly, the cutter holder can firmly clamp the collet for precise machining.

Abstract: An adaptor has a conjunction section and an abutting portion; wherein the abutting portion is axially connected to the conjunction section. The conjunction section has an external surface, a conduction recess, and an inlet hole. The conduction recess is defined in the external surface of the conjunction section and has a bottom face. The inlet hole is defined through the bottom face. The abutting portion has a cutter holder through hole defined through the abutting portion to assemble a cutter holder.
