The Diablo 9" Diamond Segmented Turbo Masonry Cut-Off Blade is an industrial-grade cutting disc engineered for demanding concrete, brick, and block applications. Built around a hardened disc body and high-quality diamond segments, this blade delivers up to 30% faster cuts than standard diamond cut-off discs, making it the go-to choice for professionals using an angle grinder or masonry cut-off saw. Whether you are slicing through poured concrete, concrete with rebar, standard brick, or cinder block, this Diablo segmented turbo blade provides the cutting speed, durability, and precision that tough masonry jobs demand.

Key Features

• Diamond segment SPEED-Edge slot design reduces vibration, providing high cutting speeds that deliver up to 30% faster cuts than standard segmented diamond discs - less vibration means cleaner cuts and less operator fatigue on long jobs
• 60% taller segments containing superior quality diamonds along with an ultra-durable bond to the disc body for up to 4X longer life - fewer blade changes and lower overall cost per cut on heavy-use masonry projects
• Hardened disc body absorbs vibration and increases impact resistance to deliver superior quality cuts in hardened materials - withstands the punishing stress of cutting rebar-reinforced concrete and dense block without warping or deflecting
• Optimized diamond segments and diamond distribution lead to constant diamond exposure for maximum performance in high speed cutting applications - consistent cutting action from the first cut to the last, reducing slowdowns during production work
• Compatible with DM 7/8" and 5/8" arbors - fits a wide range of angle grinders and masonry cut-off saws already on the job site
• Rated for dry and wet cutting - gives you the flexibility to cut with or without water cooling depending on your job site conditions
• Maximum RPM of 6,650 - designed to operate safely and efficiently at the speeds delivered by standard angle grinders and cut-off saws
• 2.6mm kerf width - minimizes material removal per pass, reducing waste and keeping cuts precise in brick, block, and concrete

Why This Product

• If you regularly cut concrete with rebar, standard blades wear out quickly and slow you down - the 60% taller diamond segments and ultra-durable bond on this blade provide up to 4X longer life in those abrasive, impact-heavy conditions.
• The SPEED-Edge slot design actively reduces vibration while increasing cutting speed by up to 30% over standard segmented diamond discs, meaning you complete more cuts in less time with better control.
• A single blade that handles concrete, brick, and block in both dry and wet cutting scenarios reduces the number of specialty blades you need to carry, streamlining your tool kit on multi-material masonry projects.
• Compatibility with both DM 7/8" and 5/8" arbors - with an included 5/8" bushing - means this blade mounts directly to the angle grinders and masonry cut-off saws you already own, with no adapter hunting required.

Frequently Asked Questions

Can this blade cut concrete that contains rebar?

Yes. The Diablo DMADST0900 is specifically rated for cutting concrete with rebar. The hardened disc body increases impact resistance and the ultra-durable diamond bond is designed to handle the sudden shock of contacting embedded steel without compromising cutting performance.

Does this blade support both dry and wet cutting?

Yes. This blade is approved for both dry and wet cutting applications. Wet cutting with water helps control dust and cool the blade during extended use, while dry cutting provides flexibility when water is not available on the job site.

What arbor sizes does this blade fit, and is a bushing included?

This blade is compatible with DM 7/8" and 5/8" arbors. A 5/8" bushing is included in the package, so you can adapt the blade to fit the appropriate spindle size on your angle grinder or masonry cut-off saw without purchasing a separate adapter.

How much faster does this blade cut compared to a standard segmented diamond disc?

The SPEED-Edge slot design delivers up to 30% faster cuts than standard segmented diamond discs. This speed improvement comes from reduced vibration and optimized diamond distribution that maintains constant diamond exposure throughout the cut.
