Pearl Abrasive LW1412CMB P4™ 14-Inch Diamond Combo Blade – 14" x .125" x 1"-20mm Arbor – 12mm Segment Rim

True Concrete & Asphalt Multi-Tasking. Turbo-Segmented Hybrid Matrix. Advanced U-Gullet Cooling Core.

The Pearl Abrasive P4 Concrete & Asphalt Combo Blade (LW1412CMB) introduces severe-duty multi-material velocity, laser-welded structural safety, and continuous dual-cutting versatility straight to your gas walk-behind saw or handheld cut-off setup. Purpose-built to overcome the primary workflow bottleneck on utility trenches and road repairs—where operators glaze over concrete blades on asphalt or melt asphalt blades on hard concrete—this 14-inch professional diamond blade features an advanced hybrid rim. It provides municipal road crews, pipe installation contractors, structural foundation teams, and masonry specialists with an incredibly aggressive cutting disc optimized to slice through cured concrete, reinforced rebar matrices, soft sandstone, green concrete slabs, and abrasive blacktop asphalt seamlessly.

Industrial longevity and excellent chip evacuation form the structural core of this premium P4™ series asset. Engineered with a massive 12mm tall diamond rim matrix, this blade blends standard segmented blocks with fast-moving turbo styling to maximize physical penetration speeds through mixed materials. The precision core is constructed from premium high-tensile steel outfitted with integrated cooling holes and deep U-shaped gullets, which actively drag cool air into the cut path to scatter friction heat during continuous dry applications. Each heavy-duty segment is securely attached using structural laser-weld technology, ensuring maximum resistance to shear forces when dropping into tough, variable job aggregates. Ready for flexible equipment mounting, the blade features a standard 1-inch full bore with an adaptable 20mm knockout bushing to match all standard gas saws.

Why the Pearl Abrasive LW1412CMB P4™ Combo Blade Dominates the Trench:

• True Combo-Bond Engineering: Specially calibrated diamond matrix lets you slice from hard cured concrete directly into abrasive blacktop without swapping blades.
• Oversized 12mm Diamond Segment Height: Extra-tall cutting rim delivers long-term durability and lower costs per inch of material cut.
• Aggressive Turbo/Segment Hybrid Rim: Unique edge structure delivers quick initial tracking while throwing material fragments out of the path immediately.
• Laser-Welded Joint Integrity: High-strength structural bonds provide superior safety and prevent accidental segment detachment during high-torque binding cycles.
• Integrated Heat Relief Vents: Custom core cooling windows prevent internal metal warping and keep the blade tracking straight during dry cuts.
