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.

These work great. Recommended

If you're looking for an inexpensive set of flush trim bits, this Wolfride 4PCS set is unbeatable on price/value. However, there's a definite trade-off in longevity: they lost sharpness fairly quickly. For the one small project I used them for, they did great, but they won't stand up to extended professional use. Highly recommended for quick, small jobs where value is the top priority.

Im someone who rarely buys cheap things. I will say I received them this morning and used 1 to trim plastic laminate shortly after receiving and it was very sharp and balanced well. very lil vibration.

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.

very good

For the money, I'm not sure you can find anything better. They cut smooth, accurately and leave a nice flush surface. These were $12 and have dramatically outperformed my expectations, highly recommend thses to anyone who needs a set of flush cut bits asap!

You get what you pay for
