Great quality router bit. It leaves a very smooth surface and works perfectly for flattening cutting boards and glued panels. The replaceable carbide inserts are a big advantage and the cutter feels well-balanced with very little vibration. I would definitely buy it again.
I was so impressed with my previous coated spiral bit that I went for the set on these. No disappointment at all. They all perform as good as the previous spiral bit. Very happy with SpeTool bits so far.
This is not my first router bit from SpeTool, so I was already expecting it to perform as advertised. It did a great job in 3/4" to 1" oak and sapele, with smooth cuts and easy movement in the router table. I used it with a skil router 2.5 HP 14 amp, and it did not even blink with pattern trimming in 1/8 to 3/16 material overhang from the template. Did not even get hot. No burn marks on the surface either. Pretty happy with this one.
I bought this and put it on the end of the Jessem box joint jig and it picks up 100% of this sawdust very nice. Very impressed. I screwed a magnet to it so it sticks right to the table and you can spin it in this place only one magnet.
