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

As a cheaper version of a pin vice this one is great for a beginner Modeller

Drill bits simply arent sharp enough even for 40K plastic

The ones I received are are so out of balance they nearly made my Makita trim router shake out of my hand they are that bad. These are too dangerous to use as having one of these fly out of my router has the potential to kill someone? In over 35 years as a cabinet maker I have never had router bits do this but you get what you pay for I suppose? As I got these as low cost units for home DIY use. They have gone striate to the rubbish bin I did keep all the roller bearings as the do fit a lot of my other router bits. I do mot recommend them at all.

The shafts bend too easily, I should have gotten the 1/2” shafts

Ive used this once to drill holes into 2 copies of super smash bros for nintendo 3ds... if you need a product that is appropriate for that very specific task, look no further. Bits were quite sharp, and it was easy to use accurately.

This item is dangerous to use. Despite the reviews I purchased anyway, was just nibbling just a small amount of material around a template, working great then all of a sudden BAM. I consider myself lucky, in addition ruined my router have to buy new router.

The bit does work but it is not strong enough to cut thick wood without chattering so if you want to cut 1 1/2 inch stock you may want a 1/2 shank bit

Piece of garbage. Only used once on 3/4” oak plywood and it almost hit me in the face. Highly do not recommend.

Good variety of sizes. Works well... Still requires quite a bit of presure to drill hard resin.

I needed a flush cut router bit that was longer than 1in. So I jumped on Amazon to see if I could find one for cheap. I found this one and thought it would be a good cheap option. However, after using it once the ballbearing failed. After replacing the bearing, I turned my router back on and the bit shank bent from the torque. The bit smashed into my router guide plate and damaged it. So in the end, I spent more in the long run. I can not recommend this product to anyone for any use. Matter of fact I recommend that you not purchase from this brand under any circumstance. If I could give negative stars, I would!
