> 3 dayEANOSIC Up-Down Compression Spiral Flush Trim Router Bit Versatile dual ball bearings allow for flush cutting as well as template use. The EANOSIC Up-Down Compression Spiral Flush Trim Router Bit is a versatile and durable tool for template cutting and flush cutting. The 1/4 inch shank and solid carbide construction make it suitable for a wide range of applications from hard and soft wood to plastic. The nano coating on the bit provides added durability and resistance to wear and tear. The unique feature of this router bit is its up-down compression design which helps to compress the material being cut, which results in a smooth and splinter-free finish. This saves a lot of sanding. This router bit is especially great for template cutting projects as it provides a precise and accurate cut every time, following the template perfectly. Exceptional value for the price. EANOSIC makes exceptional router/CNC bits!

> 3 dayThis is a very interesting take on a compression spiral bit, one Ive not seen before. Its not what you would typically expect from a compression spiral, with upward and downward flutes meeting at roughly the center of the cutting area. Instead, its more like a down-spiral bit, with a pair of shearing rakers like a Freud Quadracut bit at the tip end. I wouldnt want to use it for something you need a real compression spiral to get the best performance out of, but this has performed very nicely for me in the little bit of testing I have done so far. It was able to make nice, clean pattern cuts in walnut, oak, and pine with no fuzzing or tearout. The bit comes razor sharp, as youd expect from a spiral, and so far has held up well. I will be really interesting to see how it holds up longer term, but at least in the short term it has held and cut very nicely.

> 3 dayThis 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.

> 3 dayI 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.

> 3 dayUnreal quality for a great price. Leaves a great edge finish. No tear out or splinter. This is the 3rd brand of compression spiral I have tried and this one is far superior from the others. Used for several projects and havent seen any decline in the performance. Definitely recommend this product.

> 3 dayThis is well made, every bit as good as the more expensive Freud and Rockler bits I own. It comes in its own plastic case that closely matches the size of the bit for easy storage. It may seem trivial, but I store my bits in their original packaging, and the cases on Freud bits huge, so much bigger than the bit they hold, this case is perfect for how I like to store my bits. I haven’t used it enough to speak on its long term durability yet, but there are no red flags yet as far as the cut quality or craftsmanship is concerned. Recommended.

> 3 dayThis seems like a decent flush trim bit. The compression pattern does a decent job of making a tear-out-free cut on both the top and bottom of your workpiece. My main complaint with this is that the bearing seems a bit undersized, so if you have the cutting edge overlapping your template at all, it will cut a bit into the template, and it also leaves your workpiece ever-so-slightly undersized. Its only a slight annoyance, but its one I havent had with name brand (i.e. whiteside) router bits.

> 3 dayA spiral flush-trim bit such as this is a somewhat newish design that combines features and benefits of both upcut bits and downcut bits. And flush trim means that this bit is designed to follow a pattern along its bearing, to allow the material above the pattern to be cut flush to that pattern. You don’t want to ask a bit such as this to hog off much material; it’s forte is trimming small amounts smoothly even with sheet goods and areas of changing grain direction. So use your saw to cut close to the line, and this bit to just make that last 1/16” tight to the line and smooth. I can’t say that I have past experience with this company, but this bit does a nice job for a very good price and I would buy one of these again. I’ll update this if the bit seems to not hold up well! I hope this review has been helpful to you!
