1/4" Shank 45 Degree Lock Miter Router Bit - 1/2" 9/16" 3/4" Cutting Height Woodworking Glue Joint Tools Set 3Pcs by ROOCBIT

These are absolutely amazing! NOTAbsolutely a waste of hard earned money. Not sure what they used to measure the radius, as they are way off

While I did not experience significant cutting-head variances as did some of the other buyers of this 4-piece router bit set, I immediately noticed the quality control on the products was missing. I am working on a project requiring the routing of a single groove on the concave burnt surfaces of short sections of oak whiskey staves which will ultimately be used as cigar ashtrays. The 1/4" shanks were oversized and COULD NOT BE EASILY inserted into the collet of my 1/4" commercial router. All four shanks were measured using a Mitutoyo digital caliper and all were in the range of 3-6 thousandths oversize. I am truly disappointed Amazon Prime sells such inferior quality merchandise!

Extremely poor quality....to be expected coming from either China or some third world country.Quality similar to Harbor Freight. Could be possibly dangerous when using.

Needing a 1" router bit for light duty, soft wood grooving, with no need for an overly expensive name-brand this bit set hit the mark. 3 bits for less than the big box outlets get for 1 and the 1" bit (all I've used so far) does an excellent job for what I bought it for. A good purchase on my part.

These are good quality router bits at a fair price. Worked great on my router for cutting hand holds in a red oak cutting board. Manufacturing quality looks pretty good. Does not really look like high end steel or anything but got the job done. There was some burning on the surface of the piece but that was probably operator error. I would recommend to anyone that needs a bit to route circular slots.

These are supposed to have 1/4 inch shank, but 3 of the 4 bits are oversized so much that they do not accept a 1/4 inch I.D. bearing or fit in a 1/4" router chuck. The cutting edges themselves are not nicely curved as the photos show, but wavy at the point between radius and a vertical section of the blade. You get what you pay for.

I bought these to make my own mouldings and trim for projects. They work very well in a hand held router as well as a router table. They have a good sharp edge that does not split the wood. The bit edge does not burn or burn the wood surface. Makes woodworking fun!

Used the 1" bit to level off a 4 foot by 8 foot butcher block table made from pallet wood. Handled hogging out 3/16" to 1/4" deep passes on the bottom side, nails and all, and 4 passes ranging from 3/16" to 1/8" on the top and still in excellent shape with no visible damage.

They work perfectly.

Enjoy working with my new tool. Just what I needed!
