This reamer is an excellent addition to any industrial and scientific workplace.My analysis of this product showed that it is incredibly durable and can ream through thick materials with ease. The platinum coating ensures that it stays SHARP for a long time even with frequent use. One downside is that it is slightly heavier than other similar tools, which can cause fatigue after extended use. Overall the Champion SA80P SET 4 Platinum Maintenance Reamer is a high-performance tool that produces clean cuts on each job..
