Weiler Tiger Paw 4-1/2" Coarse Abrasive Flap Discs (10-Piece Multi-Pack)
Heavy-Aggression Type 27 Flat Grinding Wheels for Surface Blending & Finishing Hog down metal while keeping your flat surfaces perfectly level. The Weiler Tiger Paw 4-1/2" Type 27 Flap Disc 10-Pack delivers sustained material removal rates over flat structural planes. Engineered specifically for flat-plane grinding and contour blending between 0° and 15°, these high-performance wheels remove heavy weld scale quickly while ensuring a flat finish that won't leave deep gouges in your base metal.
Tool & Arbor Configuration:
- Universal 7/8" Open Arbor: Plain center hole geometry drops cleanly onto all standard right-angle grinders using common backing flanges and spanner locking hardware.
- Type 27 Flat Design Profile: Engineered to distribute structural pressure evenly across flat workpieces for smooth, professional surface finishing.
Standard Performance Features:
- 100% Zirconia Alumina Grain Composition: High-potency, self-sharpening abrasive grains micro-fracture under extreme operational pressure, continuously exposing clean, sharp points.
- Contaminant-Free Manufacturing: Formulated completely free of iron, sulfur, and chlorine (contains less than 0.1% Fe, S, Cl), making them 100% safe for sensitive stainless steel work without risking future oxidation bleed.
- Non-Scratch Phenolic Backing: Features a rugged composite backing plate that stabilizes the cloth flaps and wears away smoothly without marking your workpiece.
- Ultra-Coarse 36-Grit Sizing: Built for maximum aggression when beveling thick plate metal, heavy stock removal, and smoothing rough structural weld arcs.
