Aopin Router Bit 4mm Cutting Dia 6mm Shank Dia Single Flute Straight Bit Carbide for Woodworking Milling Cutter Tool, Green, Silver, 4Pcs

Fits router nicely i use these for freehand routing and they are very good ,good value for the price

Ordered these at short notice to replace my worn out bits. Certainly good enough to do the job if not super professional quality. I'd buy again if required

I was using these 6mm router bits to cut a 5mm deep track in morland light weight furniture plywood. They are absolutely useless. Even doing staged cuts of just 2.5mm depth at a time and going as slowly as possible, the bits just break, all bits broke in the same place as you can see from the photo. A waste of time and money. Avoid.

I was pleasantly surprised when I unpacked them to find they were in individual containers and the blade was protected by a coating of wax. The quality seems good considering the price. Did a couple of cuts with one and it made good clean cuts. With a pack of four they will last me for along period of time. Happy that I bought these which are a much better product than some I have bought. Will buy again in the future when time arrives to do so.

Two of the four ordered broke in a few seconds on my CNC, even at a really low feed rate and shallow cut. Two lasted about 20 mins of cutting before blunting. Well worth spending a bit extra on better quality.

Well packaged . Recommended

Bought these to cut 4mm channels for drawer bottoms. After cutting 3mm deep slots for about 4 linear metres in plywood the bit was looking distinctly burnt and causing significant tearout on edges of slots. Not a problem with the bits (its in the description), but worth mentioning these are 6mm and not 6.3mm (1/4inch) so make sure you are using the right collet in your router, I forgot to change mine and the bit screwed itself out of the collet before I realised and changed the collet.

Not brilliant...slightly bent so not getting true straight cut ...managed to get job done cheap alternative...better off getting more expensive ones TBO
