Wolfride 4PCS Flush Trim Router Bit Set 1/4 Inch Shank Top Bearing Flush Trim Router Bit

These have worked very well. I used them to cut openings in 7/16" OSB siding for windows and doors. The 1/4" unit worked very well but the bearing eventually ate it. This is no surprise as it is a very small bearing and it did quite a few feet (maybe 50-60 linear feet) before the bearing was burned. It is NOT a 1/4" bit, it is 7mm, I don't care what the item description says: the dial calipers say it's 7mm. The bearing stud is 3mm. I just ordered 20 of the 7mm x 3mm x 3mm bearings on Amazon so I can replace them as I want. I probably have more bearings now than the cutting edges will survive.

Nice clean sharp bits

I gave 4 stars because I found the pictures of these bits misleading. I thought I was ordering a set of different length bits. These are all the same length. The difference is how big around they are and how big the cutting blade is. The bits were very effective at flush trimming 1/4 inch cherry.

They were nice and kept their edge

Worked good does exactly what you bought it for

Bought these as a trial run / proof of concept. Used them to router some aluminum corners at slow speeds. Worked well but bearing failed after cleaning up maybe 6-8 corners. These are probably good for a few corners at best. Still gave 5 stars as it got done what was needed and proved my concept for $3.00 delivered. Now I'll buy a good one for $20-$30.

These work great. Recommended
