Spiral Flush Trim Router Bits 4 Inch Review

This router bit was a disappointment. Despite its claims to be industrial strength and scientific design, it failed to deliver the clean, accurate cuts I needed. The only positive aspect was its size but even that wasnt enough to make up for its poor performance... The worst part was the damage it did to my expensive project material, rendering it unusable. Save your money and invest in a higher-quality product from a more reputable brand..

Using this router bit, our team found that it gave very precise and clean cuts to our woodwork. The spiral design allowed for a smooth and stable operation, leaving a flawless finish on our material. We also appreciated the bit's long lifespan making it a great investment for any woodworking project .However, we did notice that the BIT was a bit loud during use. Overall, a fantastic addition to any industrial and scientific cutting tools collection..

I made 1 decent cut in 6" hole pattern for 1/2" plywood. noticed marks on the bit so instead of doing the following I took a piece of wood, pushed it just a little over the edge and 2 inches from the notch half the bit was gone.
