Description
KRONENFLEX EDGE 6″ x 1/16″ x 7/8″ Type 1 Cut-Off Wheel for Stainless Steel
Achieve deeper, straighter, and burr-free cuts with the Klingspor 317822 Kronenflex® Edge 6" x 1/16" x 7/8" Cut-Off Wheel (A 646 R). Engineered in Germany for heavy fabrication, field welding, and pipe processing, this premium abrasive disc is designed specifically for 6-inch angle grinders to deliver maximum cutting aggression and extended service life.
With a rigid 1/16" (1.6 mm) profile, the 317822 strikes the optimal balance between high-speed slicing and lateral wheel stability—eliminating blade flex when making deep cuts into heavy-wall pipe, structural steel, and solid stainless bars. Formulated completely free of iron, sulfur, and chlorine contaminants (Fe-S-Cl < 0.1%), this disc guarantees zero ferritic cross-contamination, preventing post-weld corrosion and rust spots on stainless steel (INOX) workpieces.
Key Features:
- Stable 1/16" Thickness: Provides the perfect balance of rapid cutting speed, minimal material loss, and high lateral rigidity for deep 6-inch cuts.
- INOX & Steel Formulation: Specially bonded for high cutting performance across stainless steel, carbon steel, and alloy tubing.
- Contaminant-Free Purity (Fe-S-Cl < 0.1%): Certified safe for stainless steel processing, preventing surface rust, pitting, and contamination.
- Low Thermal Load: Proprietary bond chemistry limits heat transfer, keeping the workpiece cool to prevent bluing and burr formation.
- Reinforced Fiberglass Mesh: High-tensile layered fiberglass reinforcement ensures maximum burst strength and operator safety at speeds up to 10,200 RPM.
- Universal 7/8" Bore: Standard Type 1 unthreaded center hole fits standard 6" angle grinder clamping flanges.

Frequently Asked Questions
Will this 6" cutting wheel contaminate stainless steel?
No. The Klingspor Kronenflex Edge A 646 R wheel is formulated free of iron, sulfur, and chlorine (Fe-S-Cl content < 0.1%). It will not deposit ferritic particles onto stainless steel (INOX), preventing surface corrosion and post-cut rust spots.
Why choose a 1/16" thickness over a .045" thickness for a 6" wheel?
Because 6-inch wheels reach deeper into stock, the slightly thicker 1/16" (1.6 mm) body provides the necessary lateral stiffness to prevent wheel flex and blade chatter under heavy downward force, while still delivering clean, fast cuts.
Is this a flat or depressed center wheel?
This is a Type 1 / Form 41 flat cutting wheel, designed to give you the deepest usable cut profile on 6" grinders when working on structural tubing, angle iron, and thick-wall pipe.
What is the maximum safe operating speed?
The 317822 is rated for maximum operating speeds up to 10,200 RPM (80 m/s) and complies with EN 12413 and international oSa safety certification standards.
Can this wheel be used for face grinding?
No. Thin cut-off wheels are engineered strictly for 90-degree straight peripheral cuts. Applying side pressure can break the fiberglass reinforcement and cause the disc to fail. Always use a dedicated Type 27 grinding wheel for edge beveling and weld grinding.
