7pcs 1/4" Shank Tungsten Carbide Double&Single Flute Straight Dado Router Bit Set, 3/4/5/6/8/10/12mm Cutting Diameter Trimming Cutter for Woodworking, Green

Product was just as advertised. Packaging is pretty minimal, but that's ok, the last thing I need is another storage case. Quality is average, but that's ok too. because it is really nice to finally be able to find a set of METRIC SIZED router bits. Metric tools are really difficult to find in the US, and I am really happy that I found these. Shaprpness and functionality seem to be average. I do have to note the sizes are accurate within a tenth of a millimeter

I love these things for drilling 3D prints before tapping. They're have no problem cutting metal either and they're durable enough to stay sharp. Great value, easy to use, functional. The "idea" phrases make my review look artificial.

I know these are cheap bits but, two bits broke off immediately after starting one made it 4 inches and the other 3 inches. This was with only a depth of 3/16”.

I was a bit skeptical to purchase these after I had seen others say they were prone to shattering but I have been very pleased with their durability. I have only used them on chip board and MDF boards moderatley but they cut really cleanly. For how much they cost im please with the results.

First time I used the 4mm bit it broke in half. So I changed to the 5 mm and it broke. So I went to another brand and finished my project. I would not recommend buying this product.

Worked fine. Value for the money. Labelling could be improved. Size descriptions are vague.

I needed a couple 5mm slots in a Trim Router jig I built. Two passes in 1/2" oak and the slots are perfect. The bit is still razor sharp.

I took every precaution I could to try to make sure the bit wouldn’t break. The depth of the bit was only going in to about 2 layers of ply, so not deep at all, there were no knots in it’s path, and I went super super slow. Trying as best as I could to make sure it wouldn’t snap. I only went about a foot and boom, there it went. First time using this brand new bit and immediately became money wasted. If the bit can’t even do it’s job in my scenario then it shouldn’t even exist. Don’t waste your money. I gave it 2 stars because even though I haven’t needed to use the bigger bits, I assume they work fine, but I needed the smaller bits, and they were a waste.
