ZCC Cutting Tools Co., Ltd. A12M-SDXCR-3 Boring Bar

ZCC Cutting Tools Co., Ltd. A12M-SDXCR-3 is an indexable boring bar built for precision internal turning and boring on CNC lathes and turning centers. It holds DCMT 11T3 series inserts in a steel tool body, with a 3/4 in (19.05 mm) shank and an overall length of about 150 mm, enabling it to reach small internal diameters down to roughly 25 mm. This right-hand cutting bar supports through-coolant configurations depending on the model and is designed for use in CNC machining and metalworking environments where consistent dimensional accuracy, surface finish, and repeatability matter. The product is commonly replaced by the A12M-SDXCR-3-R right-hand variant, or by equivalent bars from Sandvik Coromant and Kyocera/Mitsubishi matched to the same insert type and size.
