Description
Pearl Abrasive LW45NSP 4-1/2 x .090 x 7/8, 20MM, 5/8 Pearl P5 Hard Materials Segmented Blade, 10mm Rim
Laser-Welded "N" Shape Speed. Extra-Tall 10mm Diamond Rim. High-Tensile Anti-Wobble Core.
The Pearl Abrasive Hard Material Saw Blade LW45NSP delivers extreme abrasive speed and long-term durability in compact cutting applications. Precision-engineered with an industrial-grade matrix of synthetic diamond crystals, this professional 4-1/2 inch segmented wheel is explicitly tuned to blast through hard brick, paver bricks, cured concrete, reinforced concrete, stone masonry, block, and dense granite. It provides commercial masons, tile setters, and hardscape contractors with the aggressive cutting velocity required to maintain high-speed passes without overheating or bogging down standard handheld grinders.
Relentless heat dissipation and structural stability are built into the architecture of the Pearl P5 series. The LW45NSP features a premium, extra-tall 10mm diamond rim height that provides a significantly longer production life than cheap retail alternatives. Its cutting face uses a unique laser-welded "N" shape segment layout, which actively scoops out stone slurry and fragments while channeling a constant flow of cooling air directly across the bond core. Backed by a high-tensile steel plate core, this blade resists thermal expansion and structural flex to stop blade wobble dead, giving you straight, perfectly perpendicular cuts whether run wet or dry. Highly versatile, its standard 7/8" center hole comes packaged with 20mm and 5/8" brass reduction bushings to adapt instantly to any handheld angle grinder or small cut-off tool on your truck.
Why the Pearl Abrasive P5 4.5" Segmented Blade Controls the Grinder:
- Laser-Welded N-Shape Rim: Special structural segments actively pull debris out of the kerf channel, maximizing cutting speed while running up to 13,300 MAX RPM.
- Extra-Tall 10mm Diamond Rim: Thick, wear-resistant diamond segment column delivers an extended operational footprint, saving you money on replacement wheels.
- High-Tensile Steel Core Matrix: Rigid core handles high torsional forces, completely eliminating blade flutter or binding in deep stone paths.
- Universal Multi-Arbor Fitment: Standard 7/8" center bore features integrated 20mm and 5/8" reducer inserts to guarantee seamless multi-tool compatibility.
- Flawless Wet or Dry Adaptability: Delivers pristine cuts dry on handheld angle grinders or wet under a direct water line on masonry tile tables.
