YONICO 13169 1-Inch Radius Round Over Edge Forming Router Bit 1/2-Inch Shank

The Yonico 13171 1-1/2" Radius Round Over Router Bit is 15.5 ounces of steel, carbide and yellow enamel glory. I am building an all-redwood potting shed for my wife which includes a fold-up potting table. As I am not using metal hardware in the entire construction of the potting shed (no nails, screws or metal hinges) I wanted the table pivot point to be durable. Thus I chose a radius of 1-1/2" to ensure there was plenty of material around the wooden hinge pin to support the weight of the table and whatever was placed on it. I considered several methods of getting a gentle radius to the top edge of the table near the pivot point, including belt sanding, using various power saws, routing with a smaller radius, and combinations of all of the aforementioned. In the end I could envision that the result could be less than visually pleasing. I settled on routing the radius with a big router bit, and after doing some research and reading reviews, chose the Yonico 13171 1-1/2" Radius Round Over Router Bit. I chose this brand due to several factors, including my previous experience with this brand (see below), other reviews of this brand and price point. I pressed the "Add to Cart" button and anxiously awaited the arrival of my new router bit. It arrived within three business days via United States Postal Service in an Express Delivery envelope. The router bit was further encased in a layer of flexible corregated cardboard and securely taped closed. The router bit itself is contained (just barely...it's a really big bit) in Yonico's typical soft plastic pouch. I inspected the packaging and router bit for any damage they may have received in transit. The packaging was intact and in perfect condition, and the router bit was pristine; no nicks or cracks. At 3-1/2" across, this router bit commands respect in terms of making sure that your particular router is set to the correct speed; it promises to do some serious damage to body and equipment if things go wrong. I have a Bosch 1617EVS mounted in a Bosch RA1171 router table. The Bosch 1617EVS router manual is vague regarding the specific speed setting (page 15), stating a range of 8,000-13,500-16,500 (dial settings 1, 2 and 3, respectively) for "Nonferrous metals, larger diameter bits, and cutters". The PrecisionBits.com site recommends that bit diameters of 2-1/2" to 3-1/2" have a maximum speed of 8,000 - 12,000 RPM. Given those parameters, as well as the nature of the wood type and the amount of material to be removed, I elected to be conservative and selected 8,000 RPM. I chucked the bit, made the proper height adjustments, donned my Personal Protective Equipment (PPE) and fired up the router. NOTE: On the Bosch RA1171 Router Table you will not use any of the plastic router table inserts; the diameter of the bit _just_ fits inside the opening of the router mounting plate. Prior to purchasing this bit, make sure the opening on your mounting plate can accept a 3-1/2" diameter router bit. ALSO NOTE: I had to completely remove the RA1171 router table fence, as the outside edge of the bit would make contact with the fence facing. I could have made a sacrificial fence and SLOWLY routed a zero-clearance opening, but I elected to simply remove the fence and all featherboards from the table top and make certain I kept fingers out of harm's way. Yeah, highly unsafe, but it worked out. I wanted to be certain that the speed was correct, so I made some test cuts on some scrap redwood. I made several slow-feed shallow cuts to gently remove material. Once satisfied, I then used the same gentle process on the project stock. The Yonico 13171 1-1/2" Radius Round Over Router Bit performed excellently on every cut, and was still very sharp after making over a dozen 22"-long runs. Make sure that you use a backing board, as tear-out on an unbacked board is significant, whereas a fully-backed board resulted in a perfect cut. A little hand-sanding with 220-grit sandpaper on the project stock and the end result was a very smooth and graceful 1-1/2" roundover and a gorgeous fold-up potting table. My wife is _very_ pleased, and that is what really matters. I have purchased the Yonico 17702 70 Bits Professional Quality Router Bit Set, the Yonico 15133 Drawer Front Joint Router Bit and Yonico 14522 5 Bit Straight/Dado Router Bit Set. All of the bits I have used so far from these sets have performed well, thus I recommend these router bits to any weekend woodworking warrior or home hobbyist who is looking for economical router bits that perform every bit (pun intended) as well as more expensive bits. From my experience and perspective, Yonico router bits are not "one-time use" bits as I have read in other reviews. Properly used and properly maintained, Yonico router bits will last many years. That all being said (or written, in this case) for short-term or infrequent use, Yonico router bits are great; if you find that you are using a specific profile more often or if you are using router bits for professional purposes, definitely upgrade to one of the more renown manufacturers. Thanks, Yonico!

Very good reliable product. Low vibration, great price point. Shipped and delivered uber fast. Does not burn wood, is holding up pretty good, easy to use, performs well.

This cutter was the only option that was available in that size, on a short delivery timeline. Although we wanted a full size shaper cutter that would have been much more expensive, this tool performed very well in the shaper. The final product turned out fantastic! We plowed quite a bit of marine ply backed with mahogany through it and is seems as good as new.

Work well

Good product. It’s solid and razor sharp, as it should be. Works just great in my small Bosch router, cutting at moderate speeds. Delivery was right on time too.

Did what I needed it to do. Have only used it once. Suggest at least 3 passes if using a hand held router.

Felt great before using and after still feel the same. Cut really smooth and fast.

Nice bit for a good price

Pour un achat d'un montant de 20,85€, j'ai du payer 9€ de TVA et frais de gestion de la poste (1,33€ de TVA + 8€ de frais de gestion). Le produit, quant à lui (fraise pour toupie), est de très bonne qualité.

Aucune quincaillerie de ma région avait ce fer en stock. Je l'ai trouvé sur Amazon à une fraction du prix des grosses compagnies. Et elle est arrivée chez moi le lendemain. J'ai pu continuer mon projet rapidement. Très heureux de mon achat!

De filo durable, calidad en el material

La he usado para hacer tarugos de domino de 10 mm para la festool df500, es la medida adecuada para hacerlos, hasta ahora todo bien.

am a carpenter. use router bits all the time. bearing is silky smooth . as good as quality name brands. better than most bargain brands
