Spiral Flush-Trim Router Bits，Solid Carbide Flush Trim Router Bit 1/4-Inch Shank Spiral Flush Trim Up Cut from TACKPRO (1/4 Shank Up-Cut)

This bit works amazingly! First use was to cut some kayak hatch holes, this bit sliced through the plastic smoothly and had no chatter just a clean easy to guide cut. Ive also used it on some wood projects and it performs equally well leaving clean smooth cuts that need almost no sanding. Its also very sharp you can feel the cutting edge on the bit so be careful taking it out of the protective case. Im very happy with the performance so far and will be ordering more for my wodshop.

Best flush trim bit I have used for veneer work. Will order another.

Used it to cut plywood out in window opening made it 2 inches snapped but it was a quick 2 inches. Disappointed to say the least.
