The small diamond crosscut barrel bit is used for cutting, removing and shaping acrylic and hard gel. Its unique cross-cut pattern allows for debris to escape and not load up as quickly as smooth barrels do. The smaller barrel allows for more visibility and is great for small nail beds.
Optimal use at 10,000-20,000 RPM with an Erica’s ATA electric file. RPM will vary depending on technique, e-file and newness of bit.
