Bronze nano coating. Better heat and wear resistance. Handles high-speed cutting heat. This internal groove insert tool works on stainless steel, steel, aluminum, iron, cast iron, magnesium alloy. The advanced coating technology reduces friction during cutting, helping to lower cutting temperatures and prevent built-up edge formation. This results in smoother machining and improved surface quality across a wide range of materials.

Sharp cutting edge. Precision-ground, strong, low resistance. Chips clear smooth. Easy internal grooving. Fewer burrs, better finish. The optimized cutting geometry enhances chip evacuation, which is critical when working in confined internal spaces. By minimizing chip congestion, the tool ensures uninterrupted machining and reduces the risk of tool breakage.

Designed for small-diameter holes. Precision boring and internal grooving. Accurate dimensions, minimal errors. Good for batch work. Its compact structure allows it to access deep and narrow cavities with ease, making it especially suitable for precision components in industries such as automotive, aerospace, and mold manufacturing. Consistent dimensional accuracy makes it ideal for high-volume production.
