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.

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.

Using this bit in a router table with adequate dust collection. The top cut is nice and clean, but the underside cut is ragged. Even with the dust collection, it throws a lot of these shredded wheat shavings around. Causing me to have to stop and vacuum after every cut. Not great for time management. More expensive bits do not do this. For the money, it is sharp, it does cut and it gets the job done, but it adds time when you have to sand edges and clean up the mess.

Shipping to South Africa is a nag and takes forever but product is exceptional.

Didnt last. Used it twice and it was done.

Perfect for what I needed. Cut was clean.

Ive broken 2 of these bits cutting 1/4 aluminum.. Id like to know if theres a warranty for replacement on both of them??

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.

Terrible product and broke the first time I used it. Reached out to the seller and the offered to replace it, then gave me the run around for a week and now they say that they can’t send me a new one. Stay away from this poor crappy product
