Freud LU72M020 General Purpose Blade
Freud LU72M020 features a 20″ diameter and 72 teeth with a 1″ arbor. The blade uses TiCo HI-Density carbide for a general-purpose blend designed for maximum performance and reliability in heavy-duty cutting. The heavy-duty thick kerf and plate support stability, helping maintain a flat cut over long runs. The ATB grind and 13° hook angle optimize material removal and edge quality, making it suitable for wood and composite materials where flatness matters.
EDiamondTools 20″ Laser Welded Diamond Blade
This 20″ laser-welded diamond blade is designed for cutting concrete, reinforced concrete, brick, and masonry. It features a heat-treated blade core to reduce vibrations and improve rigidity, resulting in a smoother cut. The segmented design with 0.145″ segment width enhances safety by limiting segment breakage and providing efficient material removal for dry or wet cutting with reduced blade wandering on tough substrates.
RHAPSODY 20 Inch Diamond Concrete Blade
RHAPSODY’s 20″ diamond blade emphasizes faster cutting and longer life through higher diamond density in the segments and a robust cobalt matrix. The blade is designed for a balance of cutting speed and tool life, suitable for dry or wet cutting in concrete, reinforced concrete, masonry, and related materials. The durable construction supports repeat performance across large jobs and reduces overall operating costs by extending blade life per cut.
ORIXTREME 20 Inch Diamond Blade
ORIXTREME’s 20″ diamond blade uses segmented design and a cobalt matrix to deliver faster cutting with longer life. It aims to reduce overall operating costs by providing high cutting volume and durable construction. The blade is suitable for dry or wet cutting across concrete, reinforced concrete, masonry, brick, and block, offering a dependable option for heavy-duty masonry work and surface prep projects.
Archer Pro 20″ General Purpose Diamond Blade
Archer Pro’s 20″ blade blends general-purpose performance with diamond technology. It features laser-welded segments and Grade A diamond crystals for high performance, paired with a medium bond ideal for aggressive cutting of a wide range of construction materials. This blade targets contractors needing reliable material removal for concrete, stone, masonry, and related substrates, with a focus on consistent cutting action and durability.
Buying Guide: Key Purchase Considerations
When selecting a 20-inch blade, buyers should assess cutting material, blade type, and durability for the project at hand. Important considerations include:
- Material compatibility: Wood, concrete, reinforced concrete, stone, and masonry each require specific blade designs (general purpose vs. diamond segments).
- Blade type: General purpose carbide blades are common for wood-based tasks; diamond blades excel in concrete and masonry work, offering longer life for hard materials.
- Arbor and kerf: Confirm 1″ arbor compatibility and kerf width to ensure proper fit and minimal waste in heavy-duty cuts.
- Tooth design and density: ATB, hight density diamonds, and segment configurations affect cutting speed, edge quality, and durability.
- Dry vs. wet cutting: Some blades are optimized for both modes; consider ventilation, dust management, and material variability when choosing.
- Durability and rigidity: Heat-treated cores and laser-welded segments reduce vibration, contributing to straighter cuts and longer blade life in demanding jobs.
- Cost efficiency: Higher initial cost can be offset by longer blade life and faster cutting in repetitive tasks; analyze job frequency and material mix.
