This blade is well-suited for concrete, brick, and block work during demolition tasks where durability and speed are critical.
Buying Guide
When selecting a diamond blade for demo saws, consider blade diameter, segment design, bonding, and arbor compatibility. Larger blades cut deeper but require compatible saws and stability. Segmented blades excel in fast rough cuts, while continuous rims provide smoother finishes for masonry work. Laser-welded or hot-pressed constructions improve durability and reduce the risk of segment loss under heavy use. Heat management features, such as efficient cooling slots and coatings, help extend blade life in demanding demolition jobs. Compatibility with dry and wet cutting modes expands versatility across job sites.
Key purchase considerations include:
- Material type: Concrete, brick, stone, or reinforced substrates.
- Cutting mode: Dry, wet, or both, depending on dust control and material dust emission.
- Blade diameter: Ensure it matches the saw’s arbor and guard clearance.
- Bond and segment height: Higher segment height can improve life on hard materials; bond quality affects heat tolerance and wear.
- Durability features: Laser-welded segments, Perma-Shield coatings, and hardened disc bodies for resilience in tough demolitions.
For project planning, align blade choice with material density, required cut depth, and environmental conditions on site. In mixing dry and wet cutting needs, opt for blades explicitly rated for both modes to avoid compromising performance or safety.
