Buying Guide
Key purchase considerations include blade type (continuous rim vs. segmented vs. turbo), material compatibility (concrete, brick, block, stone), and operating mode (dry vs. wet). A thinner kerf reduces waste and increases cutting speed but can wear faster in tough material. Segment height and diamond density influence life and heat management; higher segment height and denser diamonds typically improve durability under heavy use. Compatibility with your tool’s arbor size (commonly 5/8 inches or 7/8 inches) is essential, and adapters may be needed for some blades. Consider noise, vibration, and debris management when selecting a blade for indoor jobs. For mixed materials, a general-purpose turbo or segmented blade often provides balanced performance and longevity.
