NK end-mills Four cutting-edge long cutting edge and a center cut 4NKLC 22

The sharpness was very satisfactory. However, I made a mistake in installation and damaged the cutting edge. I was aware of the need for careful handling for sharp cutting blades.

I tried digging with a cypress material suddenly at a depth of 10 mm, but it could be processed without problems. The problem is how long the sharpness lasts.

Sharpness will deteriorate quickly. .

Although it is not cemented carbide, the price is cheap and it is sufficient sharpness.

I bought the end mill with a long blade for the first time but it is very convenient and very comfortable

I use it with woodworking trimmer. Compared with router bit, finish of plate end face, tenon cut, groove cut and so on, the cut section is sharp and smooth finish can be satisfied. Two blades of long blades and four blades distinguishably from the plate end finish and the deep mortise, the two blades of short blades are distinguished by shallow tenon and groove cutting. I think that it does not change to the finished state with 2 blades, 4 blades.

I am satisfied that you can work comfortably.

I bought it as a router bit with a hobby woodworker. It is satisfied with the smoothness of the machined surface, that the noise during machining is small. I felt that kickback was also unlikely to occur.

I used it as a straight bit. You can smoothly cut unexpectedly. I also want to use it for creating a tenon.
