Klingspor Disc Flap 5" 40G CMT726Supra Abrasive mop discs for Steel, Stainless steel

Rapid-Action Hub System. Coarse 40-Grit Zirconia Alumina. Convex 6° Edge Precision.

The Klingspor CMT 726 Supra™ 5-Inch 40-Grit Abrasive Mop Disc introduces aggressive stock removal rates, professional-grade self-sharpening grain tech, and extreme production efficiency straight to your high-speed industrial grinding operations. Purpose-built to eliminate the costly, time-consuming machine changeovers common in high-volume fabrication plants—where operators must constantly stop to unthread locking nuts—this premium 5-inch rapid-mount flap disc features Klingspor's proprietary quick-lock layout. It provides industrial ironworkers, sheet metal fabricators, commercial pipe welders, and tank builders with a heavy-duty cutting profile optimized to crush through thick weld seams, sharp flame-cut slag, structural carbon steel, and hardened stainless steel alloys cleanly.

Extreme aggregate longevity and continuous edge-grinding safety form the structural core of this elite Supra-class abrasive asset. Engineered with a premium zirconia alumina grain matrix, the overlapping flaps are designed to consistently fracture under high mechanical pressure, constantly exposing sharp new cutting edges throughout the entire life of the disc to avoid loading. The internal architecture features a glass-fiber reinforced plastic backing plate set at a subtle convex 6° angle, which concentrates grinding energy onto a smaller, precise contact patch to maximize material removal per unit of time during beveling or contouring. Rated for a blistering maximum velocity of 12,250 RPM, it pairs seamlessly with modern high-power electric and pneumatic angle grinders to deliver a uniform scratch pattern with minimal vibration feedback.

Why the Klingspor CMT 726 Supra 40-Grit Disc Rules the Bench:

• Rapid-Action Hub System: Quick-lock configuration enables lightning-fast disc swaps without needing separate spanner wrenches or top locking flanges.
• Self-Sharpening Zirconia Alumina: Specially formulated crystalline grain fractures under pressure to maintain an aggressive bite on tough metals without glazing over.
• Ergonomic Convex 6° Alignment: Slanted lamella profile offers a narrow, concentrated contact surface ideal for high-pressure edge grinding and weld leveling.
• Glass-Fiber Reinforced Safety Plate: Rigid, structural backing compound absorbs heavy tool vibrations while providing premium structural burst resistance at high RPMs.
• Supra Professional Class Output: Delivers an exceptional balance of fast initial cutting aggression and extended service life under continuous industrial production demands.
