Angle Grinder Flap Discs 4.5in 40 Grit Zirconia – 40 Pack
See what customers say about shopping with FactoryFast.
Product Description
Knock down burrs with angle grinder flap discs made for weld seams, sharp metal edges and heavy stock removal. The 40 grit zirconia alumina abrasive gives you extra-coarse abrasive action for shaping, blending and surface prep, while the Type 29 profile works well at a 15–25° grinding angle.
Use these 4.5 inch flap discs when cleaning up welded frames, dressing cut steel or shaping edges before the next stage. Each disc has 72 bonded flaps for consistent contact, X-weight polyester cotton backing for edge work, and a reinforced 8-layer fiberglass plate for steady grinder handling.
Key Features
-
40 Grit Zirconia Alumina for Metal Grinding
Built for aggressive material removal, the zirconia alumina abrasive exposes fresh cutting edges as it wears. It is suited to metal grinding, sanding, weld seam blending and shaping work. -
4.5 Inch Disc Size for Right Angle Grinders
Designed for compatible right angle grinders, each disc measures 4.5in / 115mm with a 7/8in arbor hole. This makes the pack a practical choice for common grinder setups used in workshops and fabrication spaces. -
Type 29 Shape for Angled Grinding Pressure
Engineered for use at a 15–25° working angle, the Type 29 profile supports contouring and stock removal. It is useful when higher grinding pressure is needed across edges, seams and shaped surfaces. -
72 Sanding Flaps Per Disc
Features 72 tightly bonded 24 × 18mm sanding flaps on each disc. The dense flap layout helps maintain abrasive contact across metal surfaces during grinding and blending tasks. -
X-Weight Polyester Cotton Backing
The heavy-duty X-weight backing provides a balance of strength and flexibility for demanding use. It is suited to sharp edges, uneven surfaces and higher-pressure applications. -
Resin-Over-Resin Bond System
Premium resin-over-resin bonding helps retain abrasive grain during grinding. The bond system is intended for friction, heat and workshop conditions common in metalworking tasks. -
Reinforced 8-Layer Fiberglass Backing Plate
A reinforced fiberglass plate gives each disc added backing support during high-speed use. The 8-layer mesh structure helps reduce harsh vibration feel while supporting steadier handling. -
40 Pack for Ongoing Workshop Use
Whether you are grinding weld seams or preparing metal surfaces, the 40 pack helps keep replacement discs close at hand. It is well suited to fabrication, construction and regular metalworking jobs.
