The Diablo 12" Diamond Segmented Masonry Cut-Off Blade is an industrial-grade cutting disc engineered for demanding masonry and concrete work. Built by Diablo with taller diamond segments and a hardened disc body, this blade delivers up to 2X longer cutting life compared to standard diamond cut-off discs - making it a reliable choice for contractors and heavy-duty users cutting concrete, concrete with rebar, brick, and cinder block. Compatible with gas saws, masonry chop saws, and walk-behind saws, this 12" segmented diamond blade supports both dry and wet cutting applications with consistent, high-quality results.

Key Features

• Taller segments with superior quality diamonds and an ultra-durable bond to the disc body - delivers up to 2X longer cutting life versus standard diamond cut-off discs, reducing downtime and blade replacement costs
• Hardened disc body absorbs vibration and increases impact resistance - produces superior quality cuts in hardened materials even under extreme conditions, protecting both the blade and the operator
• Optimized diamond segments and diamond distribution for constant diamond exposure - maintains maximum cutting performance in high-speed applications without slowing down or glazing over
• Compatible with 1" and 20mm arbors - fits a wide range of gas saws, masonry chop saws, and walk-behind saws for versatile job site use
• Rated for dry and wet cutting - gives you flexibility to match the cutting method to your specific masonry or concrete application
• Maximum RPM of 6,400 - supports high-speed cutting in demanding masonry environments without exceeding safe operating limits
• 2.8mm kerf - removes a precise amount of material per cut, balancing speed and accuracy in concrete, brick, and block cutting tasks

Why This Product

• If you need a diamond masonry blade that outlasts standard options, the segmented design with taller diamond segments and industrial-grade diamonds extends service life up to 2X - meaning fewer blade changes across large concrete or block cutting projects
• For contractors cutting reinforced concrete or rebar-embedded slabs, the hardened disc body and impact-resistant construction handle the added stress without degrading cut quality or blade integrity
• The dual arbor compatibility (1" and 20mm, with a 20mm bushing included) means this blade mounts directly to multiple common saw platforms without hunting down additional hardware
• Wet or dry cutting capability makes this blade adaptable across job sites where water suppression may or may not be available, reducing the need for multiple specialized blades
