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)

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

Snapped in half after 1st use

Used this to trim some veneer on speaker cabinets. Half way through the second one, I noticed a line in the veneer. Turns out that the bearing was dragging. I could feel when I spun the bearing by hand that it was getting hung up. I can’t recommend this

I broke the first bit that was sent to me, but its because I didnt understand exactly what part of the bit could actually cut. At the top of the bit (the end that connects to the router), its solid cylindrical metal until you get to the point where the spiral groove starts to be cut into the shaft. That area cannot cut through the wood. Its not until you get a little further toward the bearing end that you get to the actually cutting area of the bit. I didnt realize this and was trying to cut plywood partially with that non-cutting area. It took a lot of force and ultimately the bit broke. Now that I understand, my replacement bit is working great. Ive seen a couple people complain about breaking bits, and I have to wonder if they did the same thing I did. Prior to this bit, I was using a 1/2 straight bit. It did the job, but it was a lot more work pushing it through, and the resulting cut was kind of rough. Needed a good deal of sanding. With this spiral bit, the cut is smooth as glass.

I purchased 2 router bits of this item for cutting letters w/ soft aluminum sheet. But theyve been all gone (Broken) even though I put 1 level below from max. speed of the router DeWALT and cutting slower.

Perfect for what I needed. Cut was clean.

It’s okay for the price. Ended up wearing out and getting dull and tearing out the wood after repeated cuts on soft wood. Ended up going through 3 of these just to finish the job I was doing.

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

Best flush trim bit I have used for veneer work. Will order another.

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.
