Key Features
Fast masonry cutting The segmented turbo rim is built for high-speed cutting in concrete, reinforced concrete, brick, and block when you need to get through material without babying the saw. Reduced vibration Speed-Edge slot design is made to cut vibration, which helps keep the blade tracking straighter and keeps the cut from beating up your saw in tough aggregate. Fits common arbors Runs on 1 in and 20 mm arbors and includes a 20 mm bushing, so it is ready for a lot of gas saws, masonry chop saws, and walk-behind saws.
Overview
The Diablo DMADST1400 14 in diamond segmented turbo masonry cut-off blade is a diamond masonry cut-off blade designed for cutting concrete and masonry. Model DMADST1400 is built for jobsite cutting where speed and durability matter, especially when you are pushing through hard concrete, brick, and cinder block.
This is a diamond segmented turbo cut-off blade designed for high-speed masonry cutting. The segmented turbo rim is made to move material fast while still keeping enough bite to work in tough mixes, including concrete with rebar. Diablo calls out up to 30% faster cutting versus standard segmented diamond discs, which is the difference between leaning on the saw and letting it work.
Diablo uses a Speed-Edge slot design to help reduce vibration. In real terms, that helps the blade feel more controlled in the cut and can reduce the chatter that shows up when you are cutting older, hard-cured concrete or when the saw is not perfectly supported.
The segments are designed to be taller than standard, and the disc uses industrial-grade diamonds with an ultra-durable bond. That combination is intended to keep diamonds exposing consistently as the blade wears, which is what keeps a diamond blade cutting instead of polishing the surface and glazing over.
This blade is rated for dry and wet cutting, with a maximum speed of 5,500 RPM. Match the blade rating to the tool you are running. Overspeeding a diamond blade is asking for trouble and it never cuts better.
Fit-up is straightforward: it is compatible with 1 in and 20 mm arbors, and it includes a 20 mm bushing. If you bounce between saws, that matters because you can swap the bushing instead of hunting for adapters or forcing a fit.
If you run a gas saw, masonry chop saw, or walk-behind saw and you cut concrete, concrete with rebar, brick, or block on a regular basis, this blade is aimed at you. It is built for production cutting and tough material, not occasional touch-up work.
Cut Faster Through Concrete and Block
When you are cutting slab, block, or brick, you need a blade that stays aggressive. The segmented turbo rim and diamond layout are built for high-speed cutting so you can keep moving on layout lines.
- Rated for dry and wet cutting
- Up to 30% faster cuts versus standard segmented diamond discs
Stays Controlled in Tough Material
Diamond blades do their best work when they run smooth. The Speed-Edge slot design is intended to reduce vibration and keep the cut cleaner in hardened materials.
- Hardened disc body is designed to absorb vibration and improve impact resistance
- Maximum speed: 5,500 RPM
Ready for Common Masonry Saw Setups
This is a 14 inch blade made for the tools that actually run 14 inch wheels. Arbor compatibility and included bushing help avoid fit issues when you are swapping blades on different saws.
- Arbor: 1 in and 20 mm
- Designed for gas saws, masonry chop saws, and walk-behind saws
