All materials have an optimal cutting speed which is typically stated in Surface Feet Per Minute (SFM).
SFM = Cutting tool diameter (inches) × RPM × 0.262
| Material | Cutting Speed |
| Aluminum – soft to medium-hard | 18,000 SFM |
| Aluminum – hard and/or anodized | 12,000 SFM |
| Brass – less than 150 Brinell | 10,000 SFM |
| Bronze – less than 150 Brinell | 12,000 SFM |
| Copper | 10,000 SFM |
| Lead | 14,000 SFM |
| Magnesium | 15,000 SFM |
| Plastics | 6,000–10,000 SFM |
The performance of all cutting tools, including Everlast saws, will be affected by these key factors:
- The type of machine being used
- Rigidity of the machine
- Cutting tool sharpness (dullness)
- Material feed type (manual or automatic)
- Secure clamping of material on both sides of the cutting tool
- Material being cut in single layer or stack cut
Consult with Everlast to help select the optimum saw for your cutting application.
