Yakamoz 2Pcs 1/4'' Shank Top and Bottom Bearing Guide Flush Trim Pattern Router Bit Set Woodworking Cutter Tool with 10 Pcs Top Mounted Replacement Bearings

Well made and durable product with one caution. Fine print in the instructions state, but does not emphasize, that they should not be run at > 10,000 rpm. This is critical. Run them too fast, they can self destruct. Got exciting.

Liked extra bearings for pattern trimming. Good price

Had a little tear out but that was probably my bad technique.

I was worried because other flush trim bits this long with 1/4" shafts have had bad reviews, and most of the big names don't make them this long - probably because the force applied at that length can really damage a shaft. These bits had no problems. I used them in a Ridgid compact cordless router to trim the bullnoses off thirteen 1 1/2" thick yellow pine stair treads. It was a little slow going but the bit handled it perfectly and is still going strong. Will definitely look for this brand again. Oh - and it was sharp and much less expensive than those big name brands.

The media could not be loaded. These router bits are so unbalanced it's crazy. My child can make a better bit from Legos bruh. These bits just destroyed my router base and router table. Not to mention the bit itself is toast. Actually both bits in the set were so out of balance too even at low rpms. These are not safe for even someone who knows what they're doing to use. I buy a lot of stuff from Amazon and I mean A LOT and never have I ever experienced such a horrible product. This was a brand new but never use one time, placed in my router, flipped the power switch on and within a hundredth of a second catastrophic failure. I'll be lucky if this didn't destroy my router internals also. This is seriously a major safety hazard and one that only costs a few dollars which means the majority of people buying these are inexperienced weekend warriors who don't want to spend 30 or 40 dollars on a decent bit. That's a scary thought to me.

The bits are working as expected

The bearings are trash, that is why you get so many. I was able to complete my project with them so they are passable. Less than an hour of run time destroyed 3 bearings.

The flush bit did what it was supposed. Worked great.
