Makita Diamond Blade B-69624 7 Inch Segmented (0.51 Segment Height 7/8 Arbor General Purpose Concrete Brick Block Paver Masonry Cutting Disc Tool)

Makita B-69624 7" Segmented General Purpose Diamond Blade

The Makita B-69624 7-inch segmented general purpose diamond blade cuts cured concrete, structural cinder blocks, clay facing bricks, and interlocking patio pavers with exceptional speed and aggressive material removal. Engineered with 50% taller 0.51-inch (13 mm) diamond-impregnated segments that deliver up to 4X longer operational life and 40% faster cutting speeds compared to standard turbo blades, this blade is built for high-demand masonry demolition and shaping. Outfitted with an optimized bond matrix for consistent diamond exposure and multi-arbor compatibility for 7/8-inch, 20 mm, and 5/8-inch spindles, it equips professional masons, hardscape contractors, and demolition crews with reliable, heavy-duty cutting performance across 7-inch angle grinders and masonry cut-off saws.

Best Used For:

• Concrete Slab and Foundation Demolition: Slicing through cured concrete expansion joints, footings, and structural masonry walls quickly.
• Paver and Retaining Wall Block Sizing: Parting thick interlocking landscape pavers, retaining wall blocks, and stone curbing on hardscape jobsites.
• Brick and Cinder Block Masonry Alterations: Cutting rough structural block and facing brick during window and door opening modifications.

Key Performance & Safety Features

• Aggressive Segmented Rim Design: Deep cooling slots and segmented gaps evacuate slurry rapidly to maintain high cutting velocity during heavy masonry work.
• Taller 0.51-Inch (13 mm) Segments: Extended diamond matrix depth provides 50% more wearable volume for up to 4X longer service life in abrasive materials.
• High-Speed 40% Faster Cutting: Engineered bond matrix outperforms standard turbo blades by cutting through dense aggregate up to 40% faster.
• Optimum Bond Matrix Technology: Premium industrial synthetic diamond crystals embedded in a high-grade sintered bond ensure continuous cutting efficiency.
• Universal Arbor Fitment: Standard 7/8-inch arbor hole includes nested reducer adapter bushings to fit 20 mm and 5/8-inch grinder arbors seamlessly.
• Rugged Alloy Steel Core: Heat-treated structural steel plate resists warping and thermal distortion under extreme rotational friction.

What's Included

• (1) Makita B-69624 7" Segmented General Purpose Masonry Diamond Blade
• (1) Set of Arbor Reducer Bushing Adapters (7/8" to 20 mm / 5/8")

Technical Specifications

Pro-Tip: When cutting thick concrete blocks or retaining wall pavers, let the weight of the masonry saw maintain downward feed pressure without forcing the blade; regular cooling pauses during dry cuts protect the 13mm diamond segments from thermal glazing.
