BHA 4-1/2 x 7/8 Zirconia Flap Disc T27 Angle Grinder - 40 Grit - 10 Pack
- PREMIUM ZIRCONIA FLAP DISC FOR METAL: These 4-1/2" flap discs work as a direct upgrade over standard grinding discs - same aggressive cut, without the harsh gouging. Built with premium zirconia grain, euro poly cloth, and a reinforced fiberglass backing plate, each disc keeps exposing fresh, sharp abrasive as it wears down, so cutting stays consistent from the first pass to the last.
- CHOOSE THE RIGHT GRIT FOR THE JOB: Available in 40, 60, 80, and 120 grit. Start with 40 grit for aggressive stock removal, stripping rust, and grinding down welds on stainless steel, carbon steel, cast iron, titanium, and other ferrous metals. Move up to 60 or 80 grit for blending and surface prep, or finish with 120 grit for a smooth, refined surface.
- ANGLE GRINDER COMPATIBILITY: Designed for 4-1/2" angle grinders with a 7/8" arbor and rated for up to 13,300 RPM. Compatible with DeWalt, Milwaukee, Makita, Bosch, Metabo, Ryobi, Black & Decker, Kobalt, Craftsman, Skil, Porter-Cable, Ridgid, and nearly all other 7/8" arbor angle grinders. The T27 flat profile is designed for operation at a 0° to 15° working angle, making it well suited for grinding and sanding flat metal surfaces.
- PREMIUM CONSTRUCTION FOR EXTENDED PERFORMANCE: Contains less than 0.1% iron, sulfur, and chlorine, so these zirconia flap discs stay contaminant-free on stainless steel and other rust-sensitive metals, without discoloration or corrosion after grinding. Each disc measures 4-1/2" x 7/8" with a standard arbor hole and a reinforced fiberglass backing plate, and the flat T27 profile is built for smooth, controlled flat-surface work.
- STANDARD DENSITY FOR EVERYDAY GRINDING: Built for fabrication shops, welding operations, and metalworking professionals - from auto body and collision repair to structural fabrication, pipe work, and general maintenance - with efficient, consistent material removal on stainless steel, carbon steel, hardened steel, cast iron, titanium, and other ferrous metals. As the zirconia grain wears down, it keeps exposing new sharp edges, so this flap disc keeps cutting at full speed instead of dulling out - a great pick for DIY and home shop use too.

Whether you are beveling structural steel, blending heavy welds, doing auto body repair, or tackling maintenance projects, this disc provides fast, aggressive material removal on stainless steel, carbon steel, hardened steel, cast iron, titanium, and other ferrous metals. Time is money in a commercial shop. That’s why our discs are built with premium Zirconia Alumina grain bonded to heavy-duty Euro Poly cloth. This self-sharpening abrasive continually exposes fresh cutting points as it wears, maintaining a consistent cut rate and reducing operator fatigue. The reinforced fiberglass backing plate absorbs vibration and stands up to demanding industrial use. Designed for 4-1/2" angle grinders with a standard 7/8" arbor, the flat T27 profile is perfectly suited for controlled grinding and seamless finishing on flat surfaces. Choose standard density for rapid material removal at an economical price point,ideal for general-purpose grinding, quick weld cleanup, and rust removal, or high density for additional abrasive flaps that deliver a significantly longer lifespan, consistent wear, and a smoother finish for production work where uptime is critical. For most fabrication, maintenance, and DIY applications, a standard-density 40-grit flap disc is an excellent starting point for rapid material removal. Follow with 60- or 80-grit discs as needed to achieve the desired finish. BHA builds products for hardworking professionals. We combine durable, industrial-grade materials with everyday affordability, earning a trusted track record across structural steel yards, welding shops, and construction crews nationwide.
