The DeWALT FlexVOLT Diamond Cutting Wheel is a professional-grade 9 in. segmented diamond blade engineered for demanding concrete cutting and scoring applications. Designed specifically for use with the DeWALT FlexVOLT Cutoff Saw (DCS690), this masonry blade delivers consistent, high-performance cuts through concrete block and reinforced concrete - keeping crews productive on the jobsite with less downtime and more reliable results per charge.

Key Features

• Segmented diamond cutting edge for long life in concrete cutting and scoring - the segmented rim design extends blade life, reducing the frequency of blade changes and lowering cost per cut on heavy masonry work.
• Optimized design for the DeWALT FlexVOLT Cutoff Saw (DCS690) - purpose-built compatibility means maximum runtime efficiency and peak productivity on cordless jobsite applications.
• High concentration and consistent distribution of synthetic diamonds - uniform diamond placement across the cutting edge delivers predictable, high-performance results cut after cut through concrete block.
• High-quality steel body that reduces vibration and distortion compared to a conventional abrasive disc - lower vibration translates to better operator control, cleaner cuts, and reduced fatigue during extended use.
• Capable of cutting concrete reinforced with iron up to 1/4 in. - this blade handles tough, steel-reinforced slabs without sacrificing service life, making it suited for a wide range of structural concrete cutting tasks.
• 7/8 in. arbor size - fits common cutoff saw spindles for straightforward installation and secure blade seating.
• 0.1024 in. kerf width - a precise kerf minimizes material waste and allows cleaner, more controlled cuts through masonry and concrete surfaces.

Why This Product

• Built specifically for the DeWALT FlexVOLT cordless ecosystem - if you are already running the DCS690 Cutoff Saw, this blade is engineered to work in direct partnership with that platform, squeezing the most runtime and cutting performance out of every battery charge.
• Longer service life than conventional abrasive discs - the segmented diamond rim and durable steel body are designed to outlast standard abrasive wheels in concrete cutting scenarios, reducing blade replacements on multi-day projects.
• Handles reinforced concrete up to 1/4 in. iron reinforcement - when a job involves steel-reinforced slabs or block, this blade is rated for that added challenge, removing the need to switch tools or blades mid-task.
• Reduced vibration for better cut quality and operator comfort - the high-quality steel body actively dampens vibration compared to abrasive alternatives, which means straighter cuts and less operator fatigue during prolonged concrete scoring or cutting work.
