6pcs 1/4-Inch Shank Slot Cutters Adjustable 3 Wing Router Bit Set for Woodworking Tool, 1/4", 3/16", 5/32", 1/8", 3/32", 1/16"

Packaged in 2 plastic boxes, One with arbor and 1 cutter attached and the remaining cutters on a dummy arbor with a spare shim washer in the second box. No instructions! "When changing cutters on the arbor make sure to place a shim washer between the cutter and the bearing". I spotted this but some may not. I dont think these will stack.Stamping or engraving the cutter size would have been helpful also.Works fine for T&G grooves etc. I built shaker style doors for cupboards in my garage this week. Nice clean sharp cuts. Once I dialed the cutting size and heights in, the rest was a breeze.

Purchased this set after my last cheaper set died very quickly..You clearly get what you pay for.. cut through hardwood ply like a knife..Very pleased

... to the orientation of the blades when assembling this as you can fit them upside down. They will work upside down but will burn the wood but work far better the correct way up! As no instructions came with this I didn't think about it before I started using it.Did the job at hand easily and comfortably.

Very simple to change cutters

Used on both chipboard and mdf. Good results clean cut

These cutters are not bad for the price. They came well packaged and on time. The only reason for the four star rating is that they don't arrive with enough washers to fit 1/4 shaft. I needed the smallest cutter for a job on a camper van. It's not a big problem but...

I used the 1/16" cutting blade to cut out a slot for trim edging on an arcade machine and it went pretty well. I did make the mistake of putting it in the wrong way to begin with and getting a lot of smoke. However, after remembering I had seen previous reviews about this, I corrected the blade and it cut perfectly. I probably cut about 20ft in plywood with ease on the smallest blade. I would buy again if needed.

I wanted a slot cutting set for specific reasons that were accurate and true for the sizes advertised. However this set from this seller doesn't appear correct or accurate size wise at all As the first job I wanted was to put some t moulding on to some custom furniture, this required a 1/16" (1.588mm) slot cutter to have a nice tight fit to hold the t moulding in place. This should be the smallest cutter in the set.However, after trying 2 different routers and 3 types of test wood the slot cutter appeared to be cutting a wider slot than it should be. So measuring the apparent (and definitely the smallest) 1/16" ( 1.588mm) slot cutter I was disappointed to find its bigger than it should be at a full 2mm as the picture shows. The difference might come across as meaningless to some, but the difference is the slot is to wide to hold the t moulding and it simply pops out.I then measured the 3/32" (2.381mm) cutter to find that's actually 3mm, not worth measuring the rest. Basically either I've got unlucky to receive a faulty inaccurate set of slot cutters or this set is useless and not fit for purpose when anyone buying these will likely need the exact sized spots advertised.
