Description
Klingspor 317820 5" x .045" x 7/8" Kronenflex Edge Cutting Wheel
Ultra-Thin .045" Precision Zip Cut Profile. Premium Kronenflex® Synthetic Abrasive Grain. Zero-Play Minimal Thermal Discoloration.
The Klingspor Kronenflex Edge 5" x .045" x 7/8" Cutting Wheel brings rapid material separation, clean burr-free slicing, and industrial-grade wheel longevity straight to your fabrication floor. Purpose-built to eliminate the massive material waste of thick traditional grinding wheels, the ugly blue heat discoloration common with poor-quality cut-off discs, and dangerous wheel fragmentation under heavy side loads, this premium thin profile zip-cut abrasive wheel represents an industrial engineering benchmark. It equips professional sheet metal fabricators, pipe welders, structural construction installers, and pipeline crews with a high-velocity cutting surface explicitly optimized to zip through hard stainless steel tubes, cut structural structural steel channels, slice carbon steel brackets, and segment non-ferrous metals without loading up or stalling the grinder.
Unparalleled free-cutting agility and robust mechanical safety serve as the cornerstone architecture for this Klingspor 317820 Cutting Disc. Manufactured with a perfectly tuned synthetic grain and bonding agent matrix, this ultra-thin .045-inch wheel profile experiences minimal surface friction during a cut, allowing it to glide smoothly through metals while requiring noticeably less push force from the operator. This optimized balance drastically curtails localized thermal loads, shielding sensitive stainless steel components from warp-inducing heat buildup and limiting rowdy burr formation to cut out secondary cleanup tasks. For maximum personal defense on the shop floor, the disc is heavily reinforced with structural fiberglass mesh and fully certified to comply with strict European EN 12413 and oSa safety guidelines at speeds up to 12,200 RPM.
Why the Klingspor® Kronenflex® Edge Disc Dominates High-Volume Cutting:
- Ultra-Thin .045" Zip-Cut Geometry: Shaves down material kerf loss and cuts through metal at high speed, maximizing battery lifespan on cordless angle grinders.
- Consistently Aggressive Synthetic Grain: Premium engineered grit retains its sharp cutting sharpness continuously, ensuring aggressive stock removal through its entire lifespan.
- Minimized Thermal Stress & Discoloration: High-velocity cutting action sheds heat quickly, eliminating the 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.
- oSa Certified Structural Reinforcement: Rigid fiberglass netting reinforcement guarantees superior centrifugal break-resistance at top speeds up to 12,200 RPM.
