• Characteristics
• A wide range of tooling Capable of handling various types of machining processes including grooving, traverse machining, copying, facing and boring
• Stable tool life A variety of chipbreakers improve the chip control in various applications. Prevents sudden breakage due to chip clogging
• Reduced chattering and high efficiency machining The mono-block, die steel tools reduce vibration by approximately 30% as compared to the conventional products.
• Precision edge width of polishless inserts The high precision sintering technology allows a tolerance of ±0.03 mm in grooving width for 1.25 to 6.0 mm edge width.
