Used in CNC machining centers requiring precision hole finishing, the Tecnara / Kyushu Kogu ABH-40 is a single-insert offset boring head mounted on a CAT50 integral shank with part number 150-340-6. The assembly is manufactured in Japan under the Kyushu Kogu brand, distributed in the US through Tecnara Tooling Systems. The CAT50 shank carries the designation 150-340-6, indicating a 6-inch projection from gauge line to the boring head body. The ABH-40 head provides a boring range of 1.654 inches to 2.165 inches and accepts a triangular carbide insert, visible and installed in the photos. The head body features a micrometer-style adjustment dial for fine radial positioning of the cutting edge, a hex-socket locking screw for insert and cartridge retention, and an additional setscrew port on the shank body. The CAT50 taper is fitted with a 45-degree pull stud as visible at the shank end. Kyushu Kogu boring heads are premium Japanese-made precision tools recognized in the US surplus tooling market for accuracy and build quality. The shank and head markings are clearly visible across multiple photos: "KYUSHUKOGUS / TECNARA" on the body, "ABH-40" on the head, and "TECNARA / 150-340-6" on the flange area. A carbide insert is installed and included.
