Comparison: Leroy Merlin PT vs Best Power Saw for Cutting Thick Wood Planks

Thick wood planks require specific mechanical capabilities to ensure clean cuts and motor longevity. Leroy Merlin PT offers a range of professional-grade saws from established manufacturers like Bosch, Makita, and DeWalt. These tools compete with specialized power saws often cited for high-capacity battery life and deep-reach blade configurations. Selecting the right tool involves balancing power source, blade diameter, and weight for specific job site conditions.

Quick Comparison Overview

Power Saw Performance for Heavy Timber

Thick wood planks demand high torque to prevent the blade from stalling mid-cut. The Serra circular Bosch PKS 66-2 AF 1600W 190mm com calha guia provides a 1600W motor designed for deep longitudinal cuts. This corded model eliminates concerns regarding battery depletion during long sessions. The 190mm blade diameter allows for a significant depth of cut, making it suitable for structural timber.

Specialized saws for thick wood often emphasize battery life as a core performance metric. These units frequently utilize high-voltage platforms to maintain RPM under load. While corded models from Leroy Merlin PT offer consistent power, specialized cordless competitors focus on mobility in areas without electrical outlets.

Portability and Ergonomics

Weight distribution affects the accuracy of a cut when handling heavy planks. The Serra circular Makita HS6601 1050W 165mm weighs less than many high-capacity cordless alternatives. This lower weight reduces operator fatigue during repetitive cross-cuts. However, the 165mm blade limits the maximum thickness of the wood compared to larger 190mm or 184mm models.

Cordless options like the Serra circular DeWalt DCS572NT-XJ 18V 184mm provide a middle ground. This tool uses an 18V system to drive a 184mm blade, offering the depth required for thick planks without the restriction of a power cable. Competitor models in this category are often cited for having larger footprints to accommodate dual-battery configurations, which can increase the total tool weight beyond 5kg.

Depth of Cut and Precision

Blade size directly correlates to the maximum thickness a saw can handle in a single pass. The Bosch PKS 66-2 AF includes a guide rail (calha guia) which is essential for maintaining straight lines in thick material. Thick planks often have internal stresses that can cause a blade to wander; the guide rail system mitigates this risk.

Specialized saws for thick wood may offer deeper throat depths. While the 190mm blade on the Bosch model is sufficient for most standard construction timber, some specialized competitors utilize 210mm blades for oversized beams. These larger saws often require more maintenance and more expensive replacement blades.

Battery Ecosystems and Runtime

Battery compatibility is a major factor for users already invested in a specific brand. The DeWalt DCS572NT-XJ 18V 184mm integrates with the XR battery system, allowing users to swap batteries between their saw and other tools like the Martelo perfurador DeWalt DCH133NT-XJ 18V SDS-Plus. This interoperability reduces the initial investment for professional contractors.

Competitors focusing on the "best power saw for thick wood" often prioritize battery life through larger cell packs. These packs can provide enough runtime to cut through dozens of 50mm planks on a single charge. Users must decide if the added weight of a high-capacity battery is worth the extended runtime.

Pricing and Value Tiers

The cost of entry varies significantly based on the power source and included accessories. Corded models generally offer the lowest price-per-watt, while brushless cordless kits represent the higher end of the market.

Material Removal and Finishing

Thick wood often requires sanding after the initial cut to achieve a professional finish. Leroy Merlin PT stocks several options for this stage, such as the Lixadora de banda BOSCH PBS 75 AE 750W. This belt sander operates at 11000 rpm, providing high-speed material removal for leveling rough-cut planks.

For finer finishing, the Lixadora rotorbital Makita BO5030 125mm offers a 300W motor and 24000 oscillations per minute. This tool is significantly lighter at 1.3kg, making it easier to use on vertical surfaces or overhead. Specialized saws for thick wood rarely include integrated finishing features, necessitating these secondary tools.

Drilling and Fastening in Thick Timber

Structural projects involving thick planks require powerful drilling and fastening tools. The Berbequim sem fio BOSCH Profissional GSB 18V-55 provides a brushless motor and a 13mm metal drilling capacity, which is useful for pre-drilling pilot holes in dense wood. It weighs 1.6kg, balancing power with maneuverability.

Fastening thick planks often requires high torque to sink long screws. The Aparafusadora sem fio DEWALT DCF887D2-QW 18V delivers 205Nm of torque, which is significantly higher than the 160nm provided by the Bosch GDR 18V-160 or the 165nm of the Makita DTD152Z. For heavy-duty timber framing, the DeWalt model provides the necessary force to drive fasteners through thick material without stripping the heads.

Durability and Build Quality

Construction environments demand tools that can withstand dust and drops. The Martelo perfurador Makita HR2470 780W 24mm SDS-Plus and the Bosch Professional GBH 2-26 are examples of corded tools built for longevity in harsh conditions. These tools use robust housings and high-quality internal components to handle the vibrations associated with heavy work.

Specialized cordless saws often feature magnesium base plates and electronic brakes. These features improve safety and durability but also increase the price. The choice between a corded Bosch PKS 66-2 AF and a high-end cordless competitor often comes down to the frequency of use and the availability of on-site power.

Final Considerations for 2026

Project requirements should dictate the choice between Leroy Merlin PT's inventory and specialized thick-wood saws. For stationary workshop use where planks are consistently thick, a high-wattage corded saw like the Bosch PKS 66-2 AF offers the most reliable power delivery. The inclusion of a guide rail ensures that the depth of the cut does not compromise the straightness of the line.

Mobile contractors may find better value in the DeWalt DCS572NT-XJ due to its 184mm blade and cordless convenience. While specialized competitors may offer longer battery life, the ability to share batteries with tools like the Berbequim percutor sem fios brushless 18 v com 2 baterias Dewalt DCD778D2T-QW provides a logistical advantage. Users should evaluate the total weight of the tool and battery combination, as cutting thick planks is physically demanding work that requires a stable and controllable power saw.
