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)

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.

Cuts through wood like butter and is not that expensive.

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.

You will be lucky if you can get through your first cut without the bearing spinning off and ruining your work.Avoid like the plague.$65 down the tube.They have a nerve selling this crap.

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

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

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.

Great router bit did everything I expected plus more

Great fast cutting bit, clean cuts

I like the way it cuts
