Up Down Compression Spiral Flush Trim Router Bit, 1/4 Inch Shank Solid Carbide Flush Trim Router Bits CNC Spiral Bit with Nano Coating by EANOSIC

I was using a flush trim bit with my router templates. The problem was the bit kept trying to pull the piece from my hands. I thought it was my fault, until I reread the instructions. It recommended using some brand of spirl bit. I checked here and found this gem. I popped in and went to work. First thing I noticed was zero grab. This thing was content just eating away at the wood. I even cut off chunks I couldn't hit with my jigsaw. I was extremely impressed. By the time I was done with the two dog bones in the picture, it only grabbed twice and I think it was because I didn't apply enough pressure downward. I wish I would have found this bit sooner. It has absolutely changed the game for me. It eats through dense hardwood like its nothing, it doesn't overheat, and the price is reasonable. If this one breaks I'm ordering another, overnight delivery. Trust me! If you are using templates this thing is a God send!

This bit works great with a template. Very good value. Much safer than a standard 2 cutter bit, with less tearout.

Very basic design and features. But it functions properly. I guess you can't expect too much at this price range. No regrets so far.

I had some 4/4 hard maple and some 4/4 black walnut that need to be flushed trimmed. I chose this bit on a whim and am very pleased that I did. It worked great. It performed better than some of my my expensive bits. A great product at a very fair price. Longevity remains to be seen.

do not buy these. the top comes off and the bearings fall off. i bought the 2 pack and the first one lasted about 3 minutes. the top comes off where theres supposed to be a set screw to hold them in place. but theres no screw. theres no way to tighten them. the second one i used lasted about 5 seconds before that one came apart and went flying off. i was using them in my handheld router and the one hit me in the shoulder before flying in some random direction. completely messed up my project. do not buy these, not only do they not last, but you will definitely screw up whatever you are working on. unfortunately my return window closed so im out the money i spent on them, but theres a reason they are cheap. guaranteed to fall apart and mess up you work so you are not only out the cost of bits, but the cost of material and time spent on whatever you are working on. total waste of money and time. be forwarned, these are the worst of any bit you can buy or use.

I recently purchased this EANOSIC quarter inch compression trim bit. I am really happy with it! I've been using it on a large cabinet project using cabinet grade Baltic birch plywood. With the compression bit, both sides of the plywood came out gorgeous with no tear out. Even after the large template driven project the bit remains razor sharp. This makes six bits I've bought from EANOSIC now and each has performed excellently. Most definitely would purchase again!

Perfect and good material, works great

It cut 3/4” plywood like it was butter. Make sure the guide board is secure and long enough and don't try to handle it without one. If the wood is hard, the router will pull away from you and slice quickly into places you don't want to cut. I made that mistake trying to finish the last inch to the corner of the work table I was trying to give a straighter edge. Instead it pulled itself out of my control just long enough to make a deep gouge before I could pull it away. I just didn't expect it to cut so well. But the reason I tried it first on that was because I didn't really care much about damage, since it's just a work surface that will get beat up anyway, so no big deal and it kept me from making that mistake on the shelves I was making. Not sure about how long it will last, but at least new it's pretty good for the price.

I am new to router table work and this bit was recommended, I’ve been using it successfully with acrylic templates to make shaped boards. So far it has cut well on mdf and hardwoods and my results have improved with practice.

Nice and easy cut on my guitar body. Very happy.

Used it for edge jointing, works perfectly.
