DEWALT DWA3193PCD 7-1/4" 4-Tooth PCD Fiber Cement Saw Blades (5-Pack)
The DEWALT DWA3193PCD 7-1/4-inch 4-tooth PCD circular saw blade crosscuts fiber cement lap siding, rips exterior trim panels, and slices high-pressure laminate flooring planks without rapid edge dulling. Engineered with synthetic diamond tips delivering up to 100X longer cutting life compared to standard carbide blades, this 5/8-inch arbor disc operates at rotational speeds up to 7,000 RPM across sidewinder circular saws and dedicated track cutters. Featuring an optimized 4-tooth geometry with ultra-deep clearance gullets and a thin 0.071-inch kerf that suppresses respirable airborne dust generation, this 5-pack equips siding contractors, exterior remodelers, and flooring installers with clean, chip-free cuts across highly abrasive silica composite panels.
Best Used For:
- Fiber Cement Siding and Trim Installation: Slicing crisp, chip-free factory edges on HardiePlank, HardiePanel, Allura, and Nichiha composite siding boards.
- High-Pressure Laminate Flooring Breakdown: Ripping and crosscutting dense aluminum-oxide infused laminate planks and engineered composite floor tiles without rapid tooth wear.
- Backer Board and Underlayment Prep: Sectioning cementitious tile backer boards (HardieBacker, WonderBoard) cleanly on residential bathroom and kitchen remodels.
Key Performance & Safety Features
- Synthetic Diamond (PCD) Tips: Industrial synthetic diamond cutting edges deliver up to 100X longer cutting performance in highly abrasive composite materials.
- Optimized 4-Tooth Architecture: Low tooth count minimizes mechanical friction while deep body gullets quickly evacuate dense swarf to lower tool drag.
- Airborne Dust Suppression Geometry: Specialized tooth profile cuts cleanly rather than grinding, significantly reducing respirable airborne silica particulates.
- Thin 0.071-Inch Kerf: Narrow cutting width removes less material, lowering motor strain and extending battery runtime on cordless circular saws.
- Heavy-Duty Tensioned Plate: Ground alloy steel body resists heat warping and maintains straight tracking through stacked fiber cement sheets.
- Universal 5/8-Inch Arbor Fitment: Mounts securely on standard 7-1/4" circular saws, corded sidewinders, cordless trim saws, and portable table saws.
