As a result of my tests I determined that this router bit is a complete waste of money. The cut was not clean, leaving rough edges on the wood.Additionally, the shank kept slipping, making the whole process frustrating. The only pro was that the bit arrived quickly. Save yourself the hassle and buy a better quality router bit..
Pros
Made of durable carbide material for long-lasting use.
Cons
Not compatible with routers that do not have a 1/4-inch shank size.
This tool does exactly what it says on the tin and more. It's fast, very sharp, and cuts 1/8-inch grooves in wood so fast it'll turn your head. Not only that, the price is right too. Every jack of all trades should have one in their tool box.
