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

This up down compression spiral flush trim router bit is a great finish bit. Its small size makes it much easier to maneuver in tight places or for intricate work. I am a little new at getting the right bit for what I want to do, but this seems to be a sharp bit for smooth cuts with almost no tear out. This makes this a great bit for me.

This 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.

Unreal 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.

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.

This is the first spiral bit Ive used, and I gotta say Im a convert. It just chews through material, and produces a nice clean edge. Im very pleased with this.

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 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.

Bit works great, stays sharp

Sharp and leave a good top and bottom finish. I have had no problems with bits from this company. easy to use.

A 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!
