Description
Klingspor 317818 4-1/2" x .045" x 7/8" Kronenflex Edge Cutting Wheel
Achieve fast, precise, and burr-free cuts with the Klingspor 317818 Kronenflex® Edge 4-1/2" x .045" x 7/8" Cut-Off Wheel (A 646 R). Engineered specifically for demanding metal fabrication and welding prep, this high-performance European-manufactured cutting disc blends high cutting aggression with exceptional edge stability and service life.
With an ultra-thin .045" (1.0 mm) profile, the Kronenflex® Edge wheel reduces cutting resistance and material loss, enabling rapid, cool cuts that virtually eliminate heat discoloration and workpiece warping on thin-walled tubing, sheet metal, and solid bars. It is completely free of iron, sulfur, and chlorine contaminants (Fe-S-Cl < 0.1%), making it certified food-grade and nuclear-grade safe for stainless steel processing without the risk of post-cut rust or cross-contamination.
Key Features:
- Ultra-Thin .045" Kerf: Cuts fast with minimal effort, reducing tool motor strain while maximizing cuts per wheel.
- Dual Metal Versatility: Specially bonded for optimal cutting efficiency across carbon steel, alloy steels, and stainless steel (INOX).
- Contaminant-Free (Fe-S-Cl < 0.1%): Prevents rust, surface corrosion, and pitting on stainless steel workpieces.
- Low Thermal Load: Minimizes friction heat to avoid bluing, heat staining, and burr formation—drastically reducing secondary deburring time.
- Reinforced Fiberglass Mesh: High-tensile woven fiberglass backing provides maximum lateral strength and shatter resistance at high operating speeds.
- Universal 7/8" Bore: Standard non-threaded arbor compatible with all major 4-1/2" angle grinders.

Frequently Asked Questions
Will this cutting wheel contaminate stainless steel?
No. The Klingspor Kronenflex Edge line is free of iron, sulfur, and chlorine (Fe-S-Cl content < 0.1%). This chemical purity prevents ferritic contamination and prevents post-cut corrosion or rust spotting on stainless steel (INOX).
What is the benefit of a .045" thick wheel versus standard 1/16" or 1/8" wheels?
A .045" thin kerf wheel removes significantly less material per cut. This yields faster cutting speeds, produces a cleaner, burr-free edge with reduced heat generation, and places much less strain on your angle grinder motor and battery.
Is this a Type 1 (flat) or Type 27 (depressed center) wheel?
The 317818 is a Type 1 / Form 41 straight flat cut-off wheel, maximizing usable cutting depth for straight cut-off applications on pipe, tubing, angle iron, and bar stock.
What is the maximum safe RPM rating?
This 4-1/2" disc is rated for operating speeds up to 13,300 RPM (80 m/s) and complies with EN 12413 and oSa safety certification standards.
Can this wheel be used for light grinding or deburring?
No. Thin .045" cut-off wheels are engineered strictly for 90-degree peripheral cutting. Side-loading or grinding against the face can compromise the fiberglass reinforcement and cause the wheel to break. Always use a dedicated Type 27 grinding disc for edge grinding or beveling.
