Here is the guide to eliminating faults with HSS saw blades while cutting metal pipes or tubes:
Wear on teeth
• Larger tooth pitch if the saw blade clogs with chips
• Improve coolant feed or use the correct coolant
Teeth break off
• Improve poor chip removal
• Use appropriate tooth pitch
• Optimise workpiece clamping
Tool breakage
• Re-sharpen tool
• Reduce cutting speed
Clogging and material adhesion to saw blade
• Optimise feed
• Optimise saw blade shape
• Coolant optimisation
