This professional-grade diamond saw blade set (four-tooth blade + riving knife) is designed specifically for cement-based materials such as fibre cement boards (e.g. EQUITONE, Eternit) and gypsum fibreboard. The trapezoidal or diamond tooth geometry (FT/TT) enables clean, stable cuts, reducing cracking and dust emission. The set includes a wider riving knife for precise cutting on mobile saws such as the PSS 3100 SE, MT 55 cc / 18 M bl and earlier KST-series models.
