T9200 – Automotive Parts – T9235


Although T9225 allows 1.5 times longer tool life than T9025, the tool life becomes unstable especially after machining 20 work pieces. T9235 also provides 1.5 times longer and stable tool life than T9025 due to a significant reduction in sudden fracture on the cutting edge when interrupted cutting. T9235 offers balanced performance in tool life, resulting in the best grade for this situation.
