I needed a flush router bit over 1 inch long. So I pounced on Revain to see if I could find it cheaper. Found this one and thought it would be a good budget option. However, the bearing broke after one use. After replacing the bearing, I turned the router back on and the bit shank bent from the torque. The drill hit the guide plate of the router and damaged it. So I ended up spending more in the long run. I cannot recommend this product to anyone for any use. In fact, I recommend you not to buy this brand under any circumstances. If I could put negative stars, I would!
