Interleaf flap wheels are constructed with alternating flaps of surface conditioning material and coated abrasive material for a high-cut rate and a uniform scratch pattern. Smear-resistant non-woven material creates clean, smear-proof work surfaces and provides blending action while leaving final finish on work piece. Interleaf design makes this product more aggressive than SAIT non-woven flap brushes and less aggressive that SAIT coated abrasive flap wheels. Available in Medium or Very Fine. Medium (60 or 80 grit coated abrasive material) is excellent for removing heavy oxidation, blending, cleaning, and deburring. Very Fine (120 or 180 grit coated abrasive material) is excellent for grain finishing, satin finishing, and linear scratch patterns. Used for aluminum, stainless, wood, fiberglass, ferrous and non-ferrous metals. Package of 5.
