CNC Spoilboard Surfacing Router Bit, 1/2" Shank 2" Cutting Diameter, Insert Carbide Slab Flattening Router Bit Planing Bit Wood Planer Bit by BINSTAK

I left an earlier 1 star review because my router bit (1/2" x 2" spoilboard surfacing bit with carbide inserts) arrived missing one of its three carbide inserts.The missing insert was shipped immediately (with a few extras for my trouble). I was contacted several times to be updated during the process. Very good communication, it felt like personal service. Thank for that!The tool itself exceeded my hopes. The geometry looks correct and the finish is high quality. It's a large, heavy bit, but it spun up to speed without any vibration whatsoever. (My router indicated 13,000 rpm. I was advised that the bit's maximum is 16,000. I'm using the router on a sled-type fixture- I'd be hesitant to use any bit this large in a hand-held application.)The resulting finish was beautiful. I often push my bits past their prime because of the cost, but the replacement inserts for this bit are cheap enough to never have to live with a dull cutter ever again.To sum up- Very fast shipping, wonderful customer support and an excellent product.

For a cheap bit that can be used in a medium sized router, this thing just eats slabs. I've flattened a few dozen slabs and have been very impressed. It takes upwards of 1/8" at a time if I'm not careful with my depth adjustments, and the cutters are still running really sharp on the first side. Haven't had the need to rotate them but having the option is a really nice feature.

This bit is great , it chewed through a red oak slab like it wasn't even there. I ran it in a triton 3 1/4 hp router on a sled. Was super pleased by the performance and the indexable cutters is an added bonus and value. If you do a lot of live edge flattening this bit will do the job just fine

It was my first slab to flatten, an old oak desktop. YouTube videos cautioned against running this big of a bit at full speed so I dialed it down to 9K and moved the sled by 1" increments. That left fuzzy lines across the wood so I speeded it up to 14K and that merely left some shiny, thin bars across the wood.I seemed to cut effortlessly but even going back over the desktop I had those bars. I couldn't feel them but I could see the,. Some 220/400 sandpaper on the orbital sander got rid of them but I had to sand the whole desktop.

This thing is awesome! If you're a know it all like me and have tried to surface a piece of wood with something like a motiseing bit then trust me, this thing is like 10,000 times better.....it leaves a surface every bit if not nicer than my planer. It's 100 percent worth every penny.

The media could not be loaded.  Not sure how this would perform but received it put it into the cnc and did a test run and it cuts like butter. Carbides cutters look great and are sharp. I tried cut in one direction and bidirectional and it did great. I was cutting 0.02 " , 0.03" and tried 0.125" with no problems. Shipping was quick the price is good and seems to be good quality. It really looks exactly like the SPE Tool version and used their settings with no issues.

I used this bit to flatten a 6 ft long by 35 inch wide oak woodworking bench top. The bit did a perfect job, no burning and no chattering. The router was a 2-1/4 hp Dewalt, which wasn't strained at all. The cutting edges are still as sharp as new.

Got this bit because i was tired of going through bits leveling my epoxy boards. I have used many other high end bits and they last the same amount of time, but the difference with this bit is the ability to rotate the blades and swap them out with replacement blades. Rotating alone allows for 4 times the longevity and i only have to replace the blades. I only use this for leveling on my router sled, but for this purpose alone, its the best I have ever used. I dont think you will be disappointed in using this bit. You may want to double check the tightness of the screws before using. But otherwise, its perfect. I hope this review helps others.

I purchased this to flatten large wood slabs with my hand held router(DeWalt 2.25hp) - it is working well so far. I've leveled/flattened 2 24 inch by 16 inch slabs. Zero issues, and a quality cut line. I'm very happy with this product (again, so far).Will update if any issues arise.

Product met all my expectations

Hopefully, yours will come with extra screws and the Allen key, mine was missing🤷

Item was as described and it is of very good quality with a very reasonable price tag. It arrived before the specified time. Thank you.

Have been using normal flattening bits for a few years now but I have 4 so that I always have a sharp one while the others are being sharpened. Was excited to try this and am not disappointed. This should replace all my old bits and uses the same carbide tips as my new king planer. This new technology is amazing and well worth the extra money.
