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.

The bearings disintegrated very first time using it, almost hurting me. I don’t recommend at all

works great.. and very durable..

You will be lucky if you can get through your first cut without the bearing spinning off and ruining your work.Avoid like the plague.$65 down the tube.They have a nerve selling this crap.

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

Works great on all plastics, we route many different plastics and this bit does it all!

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

Cut 3/4 mdf no problem

was a little apprehensive on the 1/4 shank size -- had been using a 1/2 shank but it got $$$ -- this bit worked perfect in a template routing project to cut a hole in the middle of a 7/8 piece of walnut -- took a little longer but one side of the hole is only 1/2 from the edge i think the smaller bite of the bite is better -- will order more

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