Product Description: The 500-9861 (also referenced as 500-0861) is a high-performance rotary blade precision-engineered for the rotary tool modules on Summa F-Series flatbed cutting systems. Manufactured from premium solid tungsten carbide, this circular knife utilizes a continuous rolling shearing action to flawlessly process challenging fibrous materials that are prone to snagging, stretching, or pulling when processed with traditional drag knives.

Featuring an enlarged 28.00 mm outer diameter (knife height) and an ultra-thin 0.60 mm profile, the 500-9861 is designed to effortlessly glide through single-ply or low-ply textiles with a maximum cutting depth of 5.00 mm. The precise 36° cutting angle delivers a razor-sharp edge, while the 8.00 mm center mounting bore ensures a perfectly concentric fit on the rotary tool's drive axle, eliminating wobble during high-speed production runs.

This blade is the definitive cutting solution for industrial fabricators and textile manufacturers processing high-tenacity, abrasive composites such as aramid fibers (Kevlar), carbon fibers, and glass fibers. It is equally highly effective at producing clean, unfrayed edges on soft goods like industrial felts, non-woven fabrics, and synthetic nylon or polyester textiles. With its high-density tungsten carbide construction, the 500-9861 provides exceptional wear resistance, dramatically extending tool life and ensuring consistent, professional-grade output in demanding manufacturing environments.
