The Diablo 18" Diamond Segmented Blade for Asphalt is a heavy-duty cutting blade engineered for professionals who demand long-lasting performance and precision on roadwork, construction, and demolition projects. Designed by Diablo for wet cutting applications, this 18" segmented diamond blade delivers up to 3X longer cutting life compared to standard asphalt blades, making it a reliable choice for high-volume cutting on asphalt, concrete, and green concrete alike. Its expertly balanced premium steel core, optimized diamond segment distribution, and hardened disc body work together to produce faster, cleaner cuts while reducing vibration, noise, and downtime on the job site.

Key Features

• Up to 3X longer cutting than standard asphalt blades - dramatically reduces blade change frequency and downtime on demanding job sites
• Taller laser welded segments containing superior quality diamonds along with an ultra-durable bond to the disc body for faster cuts and long cutting life - ensures consistent performance cut after cut without premature segment loss
• Hardened disc body absorbs vibration and increases impact resistance to deliver superior quality cuts in hardened materials such as asphalt, concrete, and green concrete - provides smooth, controlled cutting even in tough, unpredictable surfaces
• Optimized laser welded diamond segments and diamond distribution lead to constant diamond exposure for maximum performance in high-speed cutting applications - means the blade stays aggressive and efficient throughout its entire service life
• Expertly balanced premium steel core to reduce vibration and noise - improves operator comfort and blade stability during extended cutting sessions
• Undercut protection prevents premature wear of the steel body and loss of diamond segments - extends the usable life of the blade and protects your investment
• Includes a 1" arbor, ideal for walk behind saws - ready to mount on compatible equipment without additional adapters
• For wet cutting - water cooling keeps the blade and material at safe operating temperatures while flushing debris for cleaner cuts
• Maximum RPM of 4,250 - rated for high-speed use in gas saws, masonry chop saws, and walk behind saws

Why This Product

• With up to 3X the cutting life of standard asphalt blades, this Diablo diamond blade is the right choice for contractors who need fewer blade swaps and more uptime on pavement cutting, roadwork, and site prep projects.
• The segmented rim design enhances cooling and debris removal during wet cutting, which translates to faster, cleaner cuts through asphalt and concrete without overheating or clogging.
• Undercut protection guards the steel body against premature wear - a critical advantage on abrasive surfaces like asphalt where standard blades often fail at the bond before the diamonds are fully consumed.
• Compatibility with gas saws, masonry chop saws, and walk behind saws - paired with a 1" arbor included in the pack - makes this an adaptable blade that fits the tools already on your job site.

Frequently Asked Questions

Is this blade designed for wet or dry cutting?

This blade is designed for wet cutting only. Water cooling is required during use to maintain proper blade temperature, flush debris from the cut, and achieve the clean, precise results the blade is engineered to deliver.

What types of saws is this 18" diamond blade compatible with?

This blade is compatible with gas saws, masonry chop saws, and walk behind saws. It includes a 1" arbor, making it especially well-suited for walk behind saws commonly used in pavement and roadwork applications. The maximum RPM rating is 4,250 - always confirm your saw does not exceed this rating before use.

What materials can this segmented diamond blade cut?

According to the product data, this blade is rated for asphalt as its primary material. The hardened disc body also handles concrete and green concrete, making it a versatile option for roadwork, site preparation, and demolition projects where multiple surface types may be encountered.

What does undercut protection mean and why does it matter?

Undercut protection is a design feature that prevents premature wear of the steel body beneath the diamond segments. Without it, abrasive materials like asphalt can erode the steel core faster than the diamonds wear down, leading to segment loss before the blade reaches the end of its useful life. This protection helps ensure you get the full cutting life the blade is rated to deliver.
