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)

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

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

I use it for routing 3/16 beadboard. Waaay better than the formica bit I was using.

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

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

Great product

Cut very clean and without a lot of drag on the router motor...this is partially due to the small diameter, but also a sign of good design and sharp cutting edges.

Got the bit to route off the bullnose off stairs for hardwood install instead of cutting. The bit proved useless in that as it could not handle the 1 oak boards and just would not cut it. If you planning on making thick templates or routing hardwood look for something else.

Sharp long lasting bit. We use them for cutting window and door openings out when framing. Used with a trim router. I havent used in my big router yet.

Cut 3/4 mdf no problem
