The Diablo 12" Diamond Segmented Turbo Masonry Cut-Off Blade is engineered for professionals who demand fast, precise, and long-lasting cuts through the toughest masonry materials. Designed by Diablo for use with gas saws, masonry chop saws, and walk-behind saws, this 12" cut-off disc combines industrial-grade diamonds with a hardened disc body to deliver outstanding performance when cutting concrete, concrete with rebar, brick, and block. Whether you are working on a demolition site or a precision masonry job, this segmented turbo blade is built to keep up with the demands of extreme cutting applications - wet or dry.

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 - meaning less time per cut and higher productivity on the job
• 60% taller segments containing superior quality diamonds along with an ultra-durable bond to the disc body for up to 4X longer life - reducing the frequency of blade replacements and lowering overall cost per cut
• Hardened disc body absorbs vibration and increases impact resistance to deliver superior quality cuts in hardened materials - resulting in cleaner cuts even under heavy workloads and demanding conditions
• Optimized diamond segments and diamond distribution lead to constant diamond exposure for maximum performance in high speed cutting applications - ensuring consistent bite through dense masonry without stalling or glazing
• Compatible with 1" and 20mm arbors, includes one 20mm bushing - offering flexibility across a wide range of compatible saws without needing additional adapters
• Suitable for both dry and wet cutting - giving you the flexibility to work in a variety of site conditions and dust control setups
• Maximum RPM of 6,400 - matched for safe, controlled performance on gas-powered and electric masonry saws rated within that speed range
• 2.8mm kerf width - provides a clean, accurate cut path while minimizing material waste in brick, block, and concrete work

Why This Product

• When cutting time matters on large concrete or masonry jobs, this blade delivers up to 30% faster cutting speeds compared to standard segmented diamond discs - a direct productivity gain traceable to the SPEED-Edge slot design
• The 4X longer segment life means fewer blade swaps on long projects cutting concrete with rebar, cinder block, or hard brick - keeping your crew moving without costly downtime
• With compatibility for gas saws, masonry chop saws, and walk-behind saws, this single blade covers multiple tool types on the jobsite, reducing the number of specialty blades you need to stock
• Approved for both dry and wet cutting, this disc adapts to different site requirements - whether you need water cooling for dust suppression or are working in a location where wet cutting is not practical

Frequently Asked Questions

Can this blade cut concrete that contains rebar?

Yes. This Diablo 12" segmented turbo blade is specifically rated for cutting concrete with rebar, in addition to plain concrete, brick, and block. The hardened disc body and ultra-durable diamond segment bond are designed to handle the impact resistance demands of rebar-embedded concrete.

Is this blade suitable for both wet and dry cutting?

Yes. The DMADST1200 is approved for both dry and wet cutting applications, giving you the flexibility to use it with water cooling for dust suppression or in dry conditions where water is not available or practical.

What arbor sizes does this blade fit, and is an adapter included?

This blade is compatible with both 1" and 20mm arbors. It includes one 20mm bushing, so you can use it on saws with either arbor size without purchasing a separate adapter.

What is the maximum RPM for this blade, and which saws is it designed to work with?

The maximum rated speed is 6,400 RPM. This blade is designed for use with gas saws, masonry chop saws, and walk-behind saws that operate within that speed rating. Always confirm your saw's RPM does not exceed the blade's maximum before use.
