Rfvtgb 2Pcs Slot Cutter 3 Wing Router Bit 1/2 &1/4 inch Shank Adjustable Woodworking Tool

Itam was fit for the job and even when asked the seller about it nevet came back to me to sort /resolve the issue out

Next day delivery. Good router slot cutter for lots of uses. I used one for fitting trim to furniture board

...because the thread on the 1/4" spindle wasn't long enough to secure any but the thickest cutter with the washers provided. Had they included just a couple more of the thicker washers I would have given a much higher rating although I can't as yet comment on the accuracy of the results produced - I note others here have found discrepancies between the size of slots cut & the advertised cutter sizes although I doubt that will be a problem given the work I will use them for. Grateful for reviewers' comments about the need to ensure the cutters are used the right way round wrt router rotation.

After reading the description I purchased this item thinking it would do the job I required. With the product coming in two shift sizes (1/4 and 1/2 inch) I personally have a router with a 1/4 inch shaft, the cutting tools looked to be interchangeable between shafts, however they are not, nor provided with the correct items to make it so you can. The threads on the 1/4 inch shaft are not threaded low enough to allow the locking nut to clamp the cutter in place. I will have to turn the shaft down on the 1/2 shaft to fix the issue.

The cutters cannot be mounted onto the 1/4" shaft. The unthreaded part of the shaft is long enough for all 5 cutters to be mounted and only then can the locking nut be tightened.The 1/2" shaft is fine and can be used as expected.

The product was unbalance, the shaft bent and destroyed my router guard. I felt lucky not to have been damamged myself!

Had to find extra washers to use as spacers in order to tighten. Teeth are wider than they are supposed to be, and this coupled with the fact the bit are distorted means you get a slit 50% bigger than you wanted on the smaller bit

Really good quality for a DIYer
