Tool Code: 4562256111948 CNC (Computer Numeric Control) Special model with milling and workmanship. The unique U-groove construction eliminates clogging. Use it and feel it! Uses a "carbon nitride" hardening method that achieves a surface hardening layer. Can be cut: light metals such as brass and copper, as well as polyputty, solder, wood pieces, acrylic, etc. Single eye (equivalent to #1000) can be cut with less snagging and sanding of fine etched parts. The single strand (equivalent to #400) has cutting power, and the single eye is finished cleanly, resulting in a much better work efficiency. Traditional sanding becomes a V-shaped bottom of your eyes and makes it difficult to clog and the bottom of the file will become a "V" shape and the cutting of the CNC milling results in a rounded bottom and a wide bottom, making it difficult to clog clog and even if it looks clogged, you can easily remove it by brushing it with a brush.
