Klingspor SMT 974 Ceramic Flap Disc, 125 mm, Grit 60, Convex, 10 Pieces 369279

The Klingspor SMT 974 flap disc stands apart through its ceramic abrasive grain, which fractures during grinding to continually expose fresh cutting edges. This self-sharpening behaviour keeps the disc aggressive over its full service life, reducing the need for frequent disc changes on demanding jobs.

Highlights

• Ceramic abrasive grain for cool grinding and high stock removal on stainless steel and high-alloy steels
• Convex (Type 29) shape allows a steeper working angle, ideal for weld dressing and surface blending
• Fiberglass backing plate with resin bonding for stability and safety at high speeds
• 10 discs per pack, ready for angle grinders with a 22.23 mm bore

In daily use

Mount the SMT 974 on a standard 125 mm angle grinder and run it at up to 12,200 RPM. The P60 grit is coarse enough for rapid material removal yet leaves a surface ready for finishing. The convex profile concentrates pressure on a smaller contact area, making it easier to work into fillets and corners. Use it on stainless steel, high-alloy steels, and non-ferrous metals where a cool cut and long life matter.
