    Bit works great, stays sharp

    It cut 3/4” plywood like it was butter. Make sure the guide board is secure and long enough and dont try to handle it without one. If the wood is hard, the router will pull away from you and slice quickly into places you dont 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 didnt expect it to cut so well. But the reason I tried it first on that was because I didnt really care much about damage, since its 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 its pretty good for the price.

    I took this little bit out for a spin and was very happy with the results. The pictures are with a piece of 1/2” plywood. I grabbed another piece to use below it to test out the bearing portion of the bit as well, but didn’t look to see that the edge was rough, hence the less than straight cut. This bit left a splinter free cut on both sides of the plywood. It cut quickly through the 1/8” of material I was trimming off. Just keep a few things in mind. This is only a 1/4” bit. Take it easy or you’ll probably snap it. The part of the bit that makes the clean upward cuts (just above the bearing) is small. As in about a 1/4”. You have to have the bit depth adjusted correctly so that the bottom of you board is inside that cutting area or else you’ll be using the downcut portion of the bit and probably get splintering.

    I used this bit for the first time to clean up the edges of a CNC carving. I purposely cut too shallow with the CNC into a piece of walnut, then cut the carving out with a jab saw. This to me provided the worst possible scenario I could come up with regarding the wood. Hard wood with jagged overhangs that have been stressed already, and a curved edge. As for the router, I used a cordless handheld DeWalt 1/4 in router. Its large in the hand so kinda hard to hold and it is easier to accidentally tilt than a larger router. Then I flushed the corners holding the router in one hand and the carving in the other. This was the worst possible scenario I was willing to tolerate. I got the best results I have ever gotten from any flush trim bit - with the worst conditions I could come up with. There was zero tearout, and perfect alignment. Look at the pictures, they speak for themselves. I hate to write gushing reviews, but this is a standout tool that radically outperforms every other version of the tool I have ever used. Cant recommend this bit highly enough.

    Hmm, well this has a good cutting edge, seems to make a perfect edge, no wobble in the bit and good longevity. Good buy when compared to the same bit I got from HD at a better price.

    I have a couple of bits from this company, and I’m impressed with the quality. This particular 1/4” bottom bearing flush cut bit is a useful size for following tight patterns or for trimming flush to another piece. You do need to make sure your pattern is accurate and smooth as any imperfections will show, given the small bearing diameter. I’d consider this a tool for precision work, rather than hogging out the edges of countertops- solid carbide is not for forcing, and the 1/4” diameter means you need to take it slow. If you have never experienced the improved quality of cut from a good spiral ground router bit, you should give this a try.

    This bit is 1/4 from head to toe. So the bearing is also 1/4. Ive never seen one this small. Who knows how long it will last? Ill update if there are any problems. The blue coating and/or the flute design makes this bit cut very clean! For the few materials I tried, there were no blowouts or chads left hanging on top or bottom! I didnt have any kind of chatter or wobbling that I expected. However with the tiny bearing diameter, it will definitely transfer smaller imperfections from your template to the workpiece. More so than with a 1/2 bearing. This is just a lot easier to work with. I think youll have to be careful not to rely on bit color to tell you when youre making too much heat. You wont see discoloration on this coating. I guess youd have already made way too much heat if your bit was bluing. Best to keep your pass speed under control anyway.

    This is my second bit from Eanosic and just like my first one I am happy with it. It comes in a nice case for protection, and it is very sharp. It cuts material cleanly and the up down compression leaves nice edges on both the top and bottom as long as you set the bit up correctly. It is not meant to take much material off so you will need to use a bandsaw or jigsaw to cut away most of the material first. I only use it for pattern routing which is what it is meant for. Pay attention to the size of the material you are using because you may need to get a larger bit. I am using it for 3/4 material and it works great. Very happy with this bit.

    This is my first experience with an up down compression spiral flush bit. It did not disappoint. So far, I’ve only used it in testing and one small project, but the results have been very encouraging. Plywood trims were clean with no significant chipping. Softwoods like fir and cedar trimmed clean and smooth. I used it with my trim router and, as another reviewer has stated, a larger base would be helpful. I did get a few waves but that was entirely due to my too-casual technique at the time. Key unresolved issue is longevity of the product. So far I’ve seen no red flags in that regard and expect this bit to serve my purposes for many years to come. If that should change, I will update my review.

    This bit is only used to produce repeatable results using a pattern attached to the workpiece as a guide. A bearing is used to follow the pattern and neither the process or this type of router bit are anything new. What sets this bit apart is that it cutting edges are slightly angled to slice both up and down. This results in a shearing cut rather than a chipping cut and should produce a smooth cut with little or no chip-out - well see. This is also a small diameter bit. Itll get into tighter areas, but its small size requires a bit more time and patience. You cant force this bit because its cutting tip speed is much slower than a bit of larger diameter. Both rotate at the same RPM, but the larger bit has to move faster around a larger circumstance. This little bit has the potential to produce edges ready for finish, but you cant rush it. Its also important to rough-cut work pieces very close to their finished size because you cant hog material with bits as small as this. This bit is for the last 1/8 give or take, youre not going to plow with it, at least not very far before it breaks from heat buildup. Use it as intended and with care and it shouldnt disappoint.
