Sinoprotools Rabbet Router Bit 1/2 Inch Shank，Slotting Router Bit with Insert Replaceable Knives，Adjustable Multi Depths Cutter with 17 Collars Kits Set for Woodworking

No complaints, I have used it for various jobs and it performs great. Obviously can't really testify about longevity but can tell you I have been using their surface levelling bit, which is of a similar design, for over 3 years, hence the reason why I stuck with this brand. No complaints here

Needs to be run quite slowly and gives a good finish but is unhappy if there are knots in the timber.

The quality of the product is outstanding. The equivalent piece of equipment from branded name companies equates to about £110, I bought this product for £28 plus the £5 to get delivery. It’s arrived two days later from my initial order and is incredible value for the money, there is no difference between this and how much The price product which has a Brand name to it . The money this is saved means that I went out and bought the top bearing flush cutter as well for the same price. In total I spent around £60 when if I had of gone elsewhere it would’ve cost me £240 for the two same items. Absolutely incredible value and excellent quality.

Used this product for v grooving panels was extremely clean v grooving…very impressive

I cnc route alot of signs for customer and v-carve near all of them. I went though alot of 90* bits.Then I found this... never going back to standard v bits. I have had to run my spindle about 20% faster to accommodate only 1 cutting edge. The finish is glass smooth on all types of wood I have used it with so far. After about 30 signs I had to rotate the carbide insert once.

Router bit gave an excellent finish,but for a replaceable tip product, replacement tip size should be included in the ad as,hit something blades shattered, dont know if trend rota tip blades will fit as no dimensions of blades shown.

as above
