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

Needed to get straight sides on 5/4 maple boards did not have a cutter tall enough. This bit cut the hardwood easily and very smoothly. Cut 76 ft of board with no wear.

Works great

Made a deep channel in a highly figured block of walnut. Made a smooth cut until it came to a swirl of grain and it chattered,not enough to ruin the job but scary

This is solid and would probably work great if I had the proper size of router. Unfortunately it won't work in my router, though it is sharp, solid, and looks good.

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 extra long cutter with a 1/2” shank is accurate and smooth cut. without this extra long length you can’t get the job done.made my life easy.the carbide quality and a very fair price.

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.

Cutter was chipped and clearly used. JUNK
