✅ 5 Makita Premium Angled COARSE Flap Disc for Metal & Stainless Steel | 4 1/2" x 7/8" Z40 Coarse Grit for Heavy Stock Removal, Edge Chamfering/Beveling, Heavy Rust Removal & Weld Blending | Optimized for Makita 4-1/2” Angle Grinders and compatible with All 4-1/2” Angle Grinders with 5/8” arbor
✅ GRIND & CHAMFER 3X LONGER than lower quality flap discs & 15X Longer than Fiber Resin Sanding Discs due to Makita’s carefully selected Zirconia-Aluminum Oxide ingredients, Grain Grit & Proprietary Strong Bond Matrix, that gives this disc better grit-wear uniformity yielding better PERFORMANCE, STABILITY & LONGEVITY, allowing you to grind longer and more consistently than other discs in its class
✅ EASILY CONTROL & SMOOTHLY GRIND on flat or contoured METAL work surface areas including rebar, steel pipe, structural & galvanized steel, sheet metal, structural tubing, black steel, stainless steel, in addition to non-ferrous metals like, Aluminum, Zinc, Copper, Brass & Lead over an extra-long life span due to Makita’s proprietary bonded flap integrity, allowing for consistent wear and reliable conditioning with less sparks, lower vibration and less operator fatigue
✅ AVOID LOWER QUALITY & PRICED Flap Discs with low grade materials, plastic backing or improperly balanced flaps that prematurely wear and unevenly grind by relying on Makita’s proprietary, ultra strong Zirconia-Aluminum Oxide bond matrix and fiberglass backing allowing for optimal grain wear-to-exposure rate and lower vibration for the best PERFORMANCE, PRECISION, LONGEVITY, STABILITY & INTEGRITY, Grinding Longer, Faster and More Reliably than other flap discs that fall apart & disintegrate
✅ Z40 COARSE GRIT is Designed for hard and continuous Grinding, Heavy Stock Removal, Edge Chamfering/Beveling, Heavy Rust & Paint Removal, Weld Blending on Metal, Stainless Steel and Non-Ferrous materials, these Makita flap discs are Quality Assured, Contaminant-Free, Non-Smearing containing less than 0.1% Iron, Sulfur or Chlorine, for rust & corrosion-free results for your Stainless Steel material

Part of the larger Z80 & Z120 Makita Flap Disc family, this Z40 Flap Disc is ideal for aggressive, fast stock removal. For a more balanced stock removal and finish, we recommend the Z80 while the Z120 provides the most refined finishing results. All of these Makita Flap Discs are constructed with Zirconia alumina (Z), which is ideal for Stainless Steel & Metal Applications, while working well with Non-Ferrous applications. Z40 Coarse Angled Flaps are ideal for Chamfering/Beveling & Weld Blending, allowing you to remove stock on flat or contoured, edge metal work surfaces at comfortable working angles. The Angled Design allows for 90% of the abrasive material to be in contact with work surface, yielding maximal grinding surface area for greater ease, effectiveness and speed. Makita uses Fiber Glass backing plates to help absorb vibration and are consumed during use without damaging the material. Specific suited applications include: Weld head blending, remove weld slag, deburring, edge blending, surface conditioning and metal fabrication.
