ReamMeister – Nuckle joint – AH725
IMPROVED TOOL LIFE
Due to the tight hole diameter tolerance and external coolant supply machining, competitors’ tools experienced random occurrences of hole diameter reduction caused by wear and enlargement caused by built-up edge. The ReamMeister, with its excellent wear and welding resistance, achieved 2.5 times longer tool life than the conventional tool.
