S12K-SCLCR06 Boring Bar

The S12K-SCLCR06 boring bar is a versatile internal turning tool designed for CCMT and CCGT 0602 positive inserts. Featuring a 12 mm shank diameter and a rigid steel body, this holder delivers excellent stability, smooth cutting action, and high surface finish quality in a wide range of internal machining applications. Designed for precision boring, internal turning, profiling, and finishing operations, the positive insert geometry significantly reduces cutting forces compared to negative insert systems. This makes the holder ideal for machining steel, stainless steel, aluminum alloys, brass, cast iron, and other engineering materials. The reduced cutting pressure also helps minimize vibration, improving dimensional accuracy and extending tool life. The S12K-SCLCR06 boring bar is especially suitable for medium-sized bores where a balance between accessibility and rigidity is required. Its robust construction allows reliable machining performance even in deeper internal turning operations. When used with polished CCGT inserts, the tool produces excellent surface finishes in aluminum and non-ferrous materials, while CCMT inserts provide dependable performance in steel and stainless steel applications.
