The Diablo 5" Diamond Segmented Turbo Masonry Cut-Off Blade is a high-performance cutting disc engineered for demanding masonry work with an angle grinder. Built around a hardened disc body and industrial-grade diamonds, this Diablo blade delivers up to 30% faster cuts compared to standard segmented diamond discs - making it a go-to choice for contractors and tradespeople cutting through concrete, concrete with rebar, brick, and cinder block. Whether you're tackling renovation demolition, new construction, or heavy-duty block work, this turbo rim disc is designed to keep up with extreme applications without sacrificing cut quality or disc longevity.

Key Features

• Diamond segment SPEED-Edge slot design reduces vibration and provides high cutting speeds - delivering up to 30% faster cuts than standard segmented diamond discs so you spend less time on each cut and more time on the job
• 60% taller segments with superior quality diamonds and an ultra-durable bond to the disc body - provides up to 4X longer life, reducing how often you need to stop and swap out blades
• Hardened disc body absorbs vibration and increases impact resistance - delivers superior quality cuts in hardened materials, even in extreme masonry applications where lesser blades would degrade quickly
• Optimized diamond segments and diamond distribution create constant diamond exposure - ensures maximum performance and consistent cut quality during high speed cutting applications
• Compatible with 7/8", 20mm, and 5/8" arbors - provides broad angle grinder compatibility so you can use this blade with the tools you already own
• Suitable for both dry and wet cutting - gives you the flexibility to adapt to your jobsite conditions without needing a separate blade
• Maximum RPM of 12,200 - rated for the high rotational speeds of standard angle grinders, so you can run the blade safely at full tool speed
• Includes two bushings (20mm and 5/8") - so you have the adapters on hand to match your arbor without a separate purchase

Why This Product

• If you're cutting reinforced concrete or brick on a regular basis, the 60% taller diamond segments and ultra-durable bond mean you get up to 4X more life per blade - significantly lowering your cost per cut over time
• The SPEED-Edge slot design isn't just about speed - it actively reduces vibration during use, which means less fatigue for the operator and cleaner cuts in dense, hardened masonry materials
• Broad arbor compatibility (7/8", 20mm, and 5/8") with two included bushings means this blade fits a wide range of angle grinders right out of the package, with no extra trip to the hardware store
• Approved for both dry and wet cutting in concrete, concrete with rebar, brick, and block - a single blade handles the variety of materials and conditions found across most masonry jobsites

Frequently Asked Questions

What arbor sizes is this blade compatible with?

This Diablo masonry cut-off blade is compatible with 7/8", 20mm, and 5/8" arbors. Two bushings - a 20mm and a 5/8" - are included in the package so you can mount it on most common angle grinders without purchasing additional adapters.

Can this blade be used for both wet and dry cutting?

Yes. This Diablo 5" diamond segmented turbo disc is approved for both dry and wet cutting, giving you flexibility depending on your jobsite setup and the material you are working with.

What materials can this masonry blade cut?

This blade is designed to cut concrete, concrete with rebar, brick, and block. The industrial-grade diamonds and hardened disc body are engineered to maintain cutting performance in dense, hardened masonry materials even in demanding conditions.

How does the SPEED-Edge slot design benefit the user?

The diamond segment SPEED-Edge slot design reduces vibration during cutting, which enables higher cutting speeds and delivers up to 30% faster cuts compared to standard segmented diamond discs. Reduced vibration also means less operator fatigue during extended use.
