Makita Turbo Rim Diamond B-69696 4-1/2 Inch Saw Wheel (13800 Max RPM 0.51 Segment Height Concrete Brick Block Paver Masonry Cutting)

Industrial 4-1/2 Inch Continuous Turbo Disc for High-Speed Concrete Profiling and Masonry Demolition Saws

The Makita B-69696 4-1/2 Inch Turbo Rim Diamond Blade delivers professional-grade mechanical shearing precision when processing cured structural concrete, hard building brick, dense aggregate masonry blocks, and interlocking patio pavers. Engineered with a specialized turbo rim configuration, this industrial saw disc maintains continuous contact with the workpiece to produce cuts up to 30% smoother than standard segmented wheels. The balanced tool steel core is carefully tensioned to minimize machine vibration and chatter runout, expanding overall tracking accuracy up to a high-velocity 13,800 RPM maximum speed rating. Featuring multi-arbor compatibility that adapts effortlessly to 7/8-inch, 5/8-inch, and 20mm drive spindles, this versatile concrete accessory transitions seamlessly between dry aggregate abrasion environments or pressurized water-cooled wet suppression workflows.

Best Used For:

• Poured Concrete Sidewalk Sizing: Slicing smooth linear expansion joints and aggregate sections in cured structural slabs.
• Architectural Brick Retaining Walls: Trimming dense clay masonry bricks and building block edges down to precise layout dimensions.
• Interlocking Patio Paver Trim: Executing high-speed perimeter miter cuts and custom spacing runs on abrasive stone walkway blocks.

Key Performance & Safety Features

• 13mm Taller Segment Matrix: 0.51-inch specialized segments provide 50% more abrasive depth, supplying up to 4X the operational service life of competitive wheels.
• Continuous Turbo Rim: Facilitates unbroken material contact to produce finishes up to 30% smoother than conventional segmented alternatives.
• Dynamic Vibration Control: A tensioned high-tensile steel core dampens machine wobble to maximize operator accuracy and reduce hand fatigue.
• Universal Spindle Adaptability: Integrates multiple reduction rings to match standard 7/8-inch, 5/8-inch, and 20mm arbor shafts seamlessly.
• Wet and Dry Versatility: Engineered to maintain structural integrity under either continuous pressurized water streams or dry high-heat cutting cycles.

Technical Specifications

Pro-Tip: When dry-cutting hard concrete or pavers, avoid applying heavy downward force. Let the grinder's native weight pull the turbo rim through the track, and lift the blade slightly every 30 seconds to draw cool air into the gullets, preserving the diamond matrix.
