18 in All Purpose Diamond Saw Blade for Concrete & Asphalt - Deep Cut

In this review the 18 in All Purpose Diamond Saw Blade is judged on versatility and depth of cut; it is aimed at contractors and serious DIYers who need a single blade that can handle a variety of heavy materials. The biggest reason to buy is its ability to deliver deep, reliable cuts up to 6-5/8 in across hard or reinforced concrete, asphalt, granite and even ductile iron piping, making it a practical choice when one durable blade must serve multiple jobs. The review examines cut quality, durability and fit for handheld and walk-behind saws.

Key Features

• Multipurpose cutting: Cuts hard and reinforced concrete, asphalt, granite, terrazzo and ductile iron piping so a single blade can cover diverse jobsites.
• Deep cutting depth: The 6-5/8 in cutting depth lets operators make through-cuts and work on thicker slabs without changing blades.
• Segment height: A 10mm segment height provides solid wear life for extended use on abrasive materials.
• Segment width: The 0.145 in segment width balances cutting speed and material removal for controlled, stable cuts.
• Wet or dry use: Rated for wet or dry cutting, it is adaptable to high speed handheld saws and lightweight walk-behind saws to suit job and environment.

Who It's For

This blade is best for contractors, rental fleets, and experienced DIYers who encounter a range of dense materials and need a dependable allpurpose blade rather than swapping specialized blades for each substrate. It suits cutting tasks where a deep cut is required, such as pavement repairs, utility pipe work or cutting thick granite slabs.

Those who should look elsewhere include users who need extremely fine finish cuts for stone fabrication or users with saws that require non-standard arbor sizes; also, if only occasional light-duty cutting is required, a smaller, less aggressive blade may be more economical.

Pros & Cons

Pros

• High versatility across concrete, asphalt, granite and ductile iron reduces the need for multiple blades.
• Deep 6-5/8 in cutting depth handles thick material in one pass, saving time on many jobs.
• Durable 10mm segments show good wear resistance and long life under heavy use.

Cons

• Being an all-purpose blade, it is not optimized for ultra-fine finish cuts on delicate stone work.
