Frequently Asked Questions
Q: What reciprocating filer models are these CF-400 diamond files compatible with?
A: These flat taper diamond files are designed for CF-400 standard reciprocating filers. The 50mm effective bit length and flat taper profile are a direct fit for CF-400 attachments. Always verify your tool's accessory standard before purchasing.
Q: What is the difference between the three grit sizes included in this set?
A: The 150# grit is the coarsest and is best for initial shaping and rapid material removal. The 200# grit is a mid-range option for intermediate smoothing. The 400# grit is the finest and is ideal for achieving a smooth, polished surface finish on metal or glass. Using them in sequence delivers the best results.
Q: Can these files be used on glass as well as metal?
A: Yes. The emery (diamond abrasive) surface is hard enough to work on glass, metal, ceramics, and similar hard materials, making this set highly versatile for various grinding and polishing applications.
