  • Worked great for me.
Style: 1/4" Shank-1" Cutting Diameter-4 Wing
I needed to surface my CNC’s spoil board and I’m making some end grain cherry and maple cutting boards. This tool worked great for both projects.

  • Decent for the price
Style: 1/4" Shank-1" Cutting Diameter-4 Wing
Works well but the inserts aren’t very well aligned. Will need to be adjusted for flatness

Super sharp bit. No fuzzies left behind. Nice that you can rotate the bits to extend time between replacement.

  • Great for resurfacing the spoilboard
Style: 1/4" Shank-1" Cutting Diameter-4 Wing
This is perfect for resurfacing the spoilboard on my 3018 PROVer. I like the replaceable inserts which can be rotated four times for a new sharp edge. This will be great to level the surface of the board for accuracy. Very sharp.

  • Great bit for flattening on a CNC. Can rotate/replace cutters when dull
Style: 1/2" Shank-1-1/2" Cutting Diameter-4 Wing
I ordered this 4-wing, 1/2" shank, 1-1/2" flattening bit from Genmitsu for my CNC. The bit has four cutters that are each 14 mm (9/16") square. The product description says they are 12mm cutters, but I measured 14mm with my calipers. There is a wrench included to swap out the cutters, and the corner of each cutter is numbered to help keep track when you rotate them after one side gets dull. The bit is a beast and works really well. Given the sharpness of the cutters' corners, you don't want to be too aggressive with the cut or you could get a catch. I've used it to flatten log cookies (end grain) as well as facing off boards (face grain). It works great in both situations. ... show more

  • Nice surfacing bit
Style: 1/4" Shank-1" Cutting Diameter-4 Wing
Very nice surfacing bit that can be used to flatten a CNC spoilboard or to flatten small slabs. I recently used this bit to flatten a new MDF spoliboard for my Genmitsu 4040-Pro. The bit worked great with the stock 75W spindle (using a 1/4" collet) and it left a nice smooth surface on the spoilboard. The carbide cutters on the bit each with four sharp edges. When the first edge becomes dull, you can rotate the cutter to expose a new, sharp cutting edge. The bit comes with a T15 torx tool which can be used to loosen the cutters so they can be rotated. This is handy since it would be likely impossible to access the screw heads on the two cutters which are positioned vertically with typical torx bits. Overall, this surfacing bit appears to be of good quality and so far has performed well for me. At $46.99, it is not cheap, but it should significantly outlast bits which have fixed cutters so I consider it to be a good value and I recommend this surfacing bit. ... show more
