The Mafell 092649 KSB-FI 237 is a specialized 237mm circular saw blade developed specifically for parting cuts in rigid and flexible wood fiber insulating materials. Featuring vacuum-brazed carbide particles strategically grouped in clusters along the edge, this blade severs fibers with exceptional precision to deliver a clean cut without tearing.

Unlike traditional toothed blades that can easily clog when cutting insulation, the KSB-FI produces a very fine sawing action that significantly reduces dust pollution and decreases the volume of chips requiring disposal. This design minimizes the likelihood of blockages in vacuum channels, improving overall dust extraction efficiency. Because of its self-sharpening carbide clusters, both sides of the blade can be used, ensuring a very long service life with reduced maintenance requirements.

This blade is ideal for cutting wood fiber insulating materials, plastic-derived rigid foam, lathing, and wood wool panels. It is designed for use with Mafell K 85 Ec, K 85-18, and KSS 80 Ec/370 portable circular saws and cross-cutting systems.

Features & Benefits

• Optimized Tooth Clusters: Vacuum-brazed carbide particles efficiently sever rigid and flexible insulation fibers for clean, precise edges.
• Improved Dust Extraction: Fine sawing action reduces large chip volumes and prevents blockages in dust extractor vacuum channels.
• Dual-Sided Cutting: The unique cluster arrangement allows cutting on both sides of the blade to maximize work efficiency.
• Self-Sharpening: Specialized carbide particles continuously expose new cutting edges for an extended service life.
• Reduced Maintenance: Cleaner cuts and reliable dust extraction reduce the need for frequent tool and workspace cleaning.
