Description
Klingspor 317821 5" x .045" x 7/8" Kronenflex Edge Depressed Center Cutting Wheel
Flush-Cutting Type 27 Depressed Center. Ultra-Thin .045" Kerf Profile. Premium Kronenflex® Low Thermal Load Abrasive Grain.
The Klingspor Kronenflex Edge 5" Depressed Center Cutting Wheel brings rapid material separation, clean flush-slicing agility, and industrial-grade wheel longevity straight to your production floor. Purpose-built to eliminate the binding limitations of flat cutting wheels when working close to welds, the ugly blue thermal discoloration common with cheap abrasives, and the dangerous fragmentation risks of budget discs, this premium Type 27 depressed center zip wheel serves as an industrial engineering benchmark. It equips professional sheet metal fabricators, pipe welders, pipeline crews, and structural steel installers with a high-velocity cutting edge optimized to slice through stainless steel tubes, crop structural carbon steel channels, flush-cut protruding bolts, and segment heavy flat iron bars without loading or stalling the grinder.
Unparalleled free-cutting precision and structural safety serve as the foundational architecture for this Klingspor 317821 Cutting Disc. Featuring a specialized depressed center (Type 27) shape, this wheel allows the locking nut of your angle grinder to sit recessed within the wheel profile, enabling smooth, flush-to-surface cuts that flat wheels simply cannot achieve. The ultra-thin .045-inch profile slices a narrow kerf path through metal, minimizing friction and operator push-force to significantly lower local thermal loads and prevent warping on sensitive stainless steel (Inox). Heavily reinforced with multi-layered fiberglass mesh for ultimate break-resistance, the disc is certified to meet strict European EN 12413 and oSa safety guidelines at speeds up to 12,200 RPM.
Why the Klingspor® Kronenflex® Edge Depressed Center Disc Dominates the Shop Floor:
- Type 27 Flush-Cutting Hub: Depressed center structure configuration allows grinder adapters to run flush against the metal surface, opening up clean close-quarters cuts.
- Ultra-Thin .045" Free-Cutting Kerf: Slices rapidly through metal with minimal resistance, significantly reducing battery draw on cordless 18V angle grinders.
- Zero-Play Minimal Thermal Discoloration: High-velocity cutting action sheds frictional heat quickly, eliminating ugly blue tempering stains on sensitive stainless metals.
- Low Burr Edge Finish Production: Produces immaculate, laser-straight cuts that drastically lower the need for tedious secondary grinding or manual deburring work.
- oSa Certified Structural net Reinforcement: Rigid fiberglass netting reinforcement guarantees superior centrifugal break-resistance at top speeds up to 12,200 RPM.
