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

I tried these out today on a piece of butcher block I am turning into a cutting board. The first one bent and got unstable the second it touched the wood...I am not exaggerating. I tried to use it, but it was too unstable. I loaded the second one into my router and it made it around one long side and one short side and then half way up the other long side before it bent and was no longer usable. I was not putting any more pressure on them than I had to to keep it against my template. These are junk.

I use these to drill the barrels on my 40k miniatures, works a treat.

Abolutely thrilled with this hand drill, didnt expect it to arrive as soon as it did, super fast delivery which was great as I urgently needed it. Works like it says and was very pleased
