I agree with KP91 about the 1/2 inch shanks,,,I was using a 1/4 inch shank flush trim bit when I started to make the first batch of those canes,,, and I did not get very far and I heard a little "plink" and then almost instantly,, a little "Bang" clear across the shop in a pile of boards leaning against the wall,,, so much for the 1/4 inch trim bit,,,,, just glat it took off in that direction,,,, Never even went to search for what was left,,, just went to Lowes and bought a 1/2 inch shank trim bit and so I could get back to work,,, It was a 2 flute of 1 1/2 inch lenght, it worked ok but after a while it seemed to burn quite easily,,, so I went online and bought 3 fluted trim bit from White Side,,, it worked a lot better and the finish showed the difference,,, so you might consider a 3 flute over a 2,,, the cost was not a lot more and it did cut smoother,, I am sure that eagle america probably makes them also,,,
