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)

Didnt last. Used it twice and it was done.

Get the other style. This one pushes the tool away. The other will pull it down.

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.

Bit snapped first time using it. Wasnt even going through material fast, it just snapped. Save your money and look somewhere else.

Cuts through wood like butter and is not that expensive.

Bearings failed third time using it. Edit: Bit was replaced and no problems yet.

Worker better than perfect

Whiteside quality at half the price

Tried to use on 1/2 plywood broke instantly. Luckily the shrapnel didnt hit me. Highly disappointed.

Definitely one of my favorite bits. Such a clean finish!
