Accusize Industrial Tools Double Flute Extra Long Straight Carbide Tipped Router Bit, 1/2'' Diameter, 3'' Depth, 1/2'' Shank, 4.7'' Oal, 0021-0828

I bought this to do some really deep mortises on a gate I was building. The quality and sharpness of this bit is very good. It chattered a bit when really deep (3.5") but that can be expected and it does not harm the cut at all. As good as bits that are twice the price. I would purchase again.

I intended to use this router bit to clean out a deep mortise in fir. I'd pre-drilled the bulk of the mortise. This bit lasted about 2-3 minutes before it chipped. There was some chattering but not that bad. The cutting edges are obviously brittle. I should have paid more attention to the negative reviews.

This product is garbage. Used it for the first and only time today. First cut trying to mortise soft pine the shaft warped and took a nick out of the "carbide" cutter. It's too late to get a refund so I'll just warn everyone not to waste their money. I just glad it didn't bend the shaft on my router.

Using this for surfboard building. What a great cheat! I am cutting foam, I have no real load on this so take that into consideration. It is a solid bit though

This will allow me to make tapered furniture legs.

I used this with a straight edge clamp and DeWalt router to straighten out the edge on a 6" thick table. There were no issues with making a nice clean and straight edge. Top surfaces were made of MDF (1 1/2 inches thick), supported by pine lumber. Bit is still sharp; no damage sustained.

I bought this specifically to make box joints using a home-made jig. Also my box joint jig required a bit of this length. So far it has worked as expected, making professional looking box joints.

Carbide came apart in the first 30 seconds of running in poplar. This is dangerous junk causing bits of metal flying everywhere at very high speed.

This bit was sold as new, but clearly was used. I took these photos as soon as I open the package. The shaft clearly had marks from where it had previously been in a chuck. The tip if one blade was chipped. The side of the other blade was chipped. The surface of the bit was abraded. Not good. Not safe to sell a used and damaged bit for routing where these bits spin at up to 25,000 RPM.

Was cheaper than many, but very solid. I used it to cut a circle on 1.5" thick butcher block counter top (birch). Very clean clut, no hesitation and no burning makrs. Very happy with the choice.

Unfortunately broke right away the day we got it. Was very disappointed. Was really hoping it would work out.

Worked great to prepare an edge to glue and make a 2' th Catalpa live edge slab table 5' x 11'.

Works well
