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)

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.

Works great

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.

WORKS GREAT with my dewalt drill. Easily cut through drywall and 1/2 inch plywood. By far a great investment. Used for 2 days straigh and bit is still sharp. Cuts are clean and concise.

I had two of em and they broke very easily

They hold up pretty well we use on mdf all day. Last about a month

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

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.

I ordered this bit in hopes it would give me a nice clean cut with my router table. First one spun the bearing off within the first two minutes of use. I ordered a replacement and the second one snapped in half and flew across the shop after trimming about 4 of 1/4 acrylic sheet. Avoid this one

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