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)

First cut I used it was amazing, then when I did my second cut the end of it heated up, Im not sure if it was a bearing or not as it doesnt spin now and not sure if it did before, but it discolored the bit. Im really sad about it because my first cut went so well. Also I was cutting 3/4 mdf applying very little pressure to the bit trying to let it do all the work

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

I needed a small diameter router bit for trimming 1/2 plywood. This product is fabulously sharp and very easy to use. Highly recommended!

Less than 10 seconds into my first cut with pine plywood and it snapped in half. Very poor product

I was having trouble with my flush trim bit. The detail I was trying to create was somewhat delicate and my bit kept ripping up the edge. This bit left a perfect edge and gave me a much nicer cut. The price was good too. I’m very happy with this bit and would recommend it.

I used this bit to trim 3/8 drywall around a door. It cut 4 ft of drywall then the bit broke in the center of the shaft. I didnt expect it to be ultra-durable, but this is terrible. Not worth the risk of the bit exploding during light use.

Trimmed without splintering

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

This not broke the first time I tried to use it. It is very flimsy and not for heavy duty use by any means.

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
