Diablo's specialty Non-Ferrous Plastics thin kerf blade has a Triple Chip Grind TCG Teeth Design for long life and a clean， burr-free finish. Diablo's blade is ideal for on-the-job cutting of nonferrous metal such as copper pipe， aluminum extrusions， brass plate. New advanced laser-cut stabilizer vents absorb noise and vibration and prevent sideways movement for precise， clean cuts. Precision tensioning is a computer controlled process to keep the blade flat for a better quality finish.
