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)

Great router bit did everything I expected plus more

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.

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.

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

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

Whiteside quality at half the price

The bit snapped in half during first use. Still not able to find the other half. No injuries, so could have been much worse, but not impressed.

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 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.

This was the perfect bit for my job. Cut out 10 window openings and it’s just getting started.
