Buying Guide
- Blade type: Segmented blades excel in fast, aggressive cuts and debris removal; continuous rims provide smoother cuts on softer materials; turbo blades offer a balance of speed and control.
- Material compatibility: Check if the blade is rated for concrete, masonry, brick, stone, tile, or granite, and whether it supports dry, wet, or both cutting modes.
- Arbor compatibility: Ensure the blade’s arbor size matches your grinder (common sizes include 7/8″ and 5/8″ with 20mm reductions).
- Durability features: Look for full-hardened steel bodies, high diamond segment height, and cooling design to minimize overheating and V-bloom.
- Set versus single blade: Sets provide versatility for mixed-material jobs; single blades can be optimized for a specific task or material.
- Budget and frequency: For frequent masonry work, investing in a high-life blade may reduce downtime; for occasional use, a budget blade with solid performance can be sufficient.
