Diamond Cutting Disc Makita D-41632, 125×22.23 mm, Turbo, Dry Cutting for Concrete

Makita diamond cutting disc D-41632, 125×22.23 mm, Turbo, Dry Cutting for Concrete is a turbo-rim diamond blade engineered for dry cutting of concrete and masonry with angle grinders that accept a 22.23 mm arbor. The turbo rim profile combines continuous cutting performance with improved chip evacuation to maintain cutting speed and edge quality on dense materials. The 125 mm diameter offers a balance between cutting depth and tool control for contractors and skilled DIY users performing on-site concrete, block, or paving work.

Advantages

The turbo rim geometry promotes faster material removal and efficient dust and chip clearance while preserving a consistent kerf for controlled cuts. The diamond-impregnated rim is optimized for dry operation on concrete and similar abrasive materials, reducing the need for cooling water and allowing use in environments without wet-cutting setups. The 22.23 mm arbor fit ensures secure mounting in common angle grinders, and the 125 mm size delivers manageable cutting depth with good maneuverability.

Suitable for

• Dry cutting of concrete slabs, blocks and curbs
• Cutting masonry, bricks and pavers
• On-site repair and renovation tasks where wet cutting is not available
• Contractor and experienced DIY angle grinder work

Key specifications

• Disc diameter: 125 mm
• Arbor bore: 22.23 mm
• Rim type: turbo
• Cutting mode: dry cutting
• Primary material application: concrete and masonry

How to use

Mount the disc on a compatible angle grinder with a 22.23 mm arbor and ensure the machine is disconnected from power before installation. Verify that the disc rotation direction matches the grinder’s indicated rotation and tighten the flange securely according to the grinder manufacturer’s instructions. During cutting, use steady feed pressure, allow the blade to reach cutting speed before engaging the material, and avoid forcing the disc through the workpiece. Take breaks between long cuts to allow the blade and tool to cool in dry cutting applications.

Usage recommendations

Wear appropriate personal protective equipment including eye protection, hearing protection and an approved dust mask or respirator for silica-containing dust. Use cutting techniques that minimize sparks and dust clouds, maintain firm two-handed control of the grinder, and work in well-ventilated areas. Inspect the disc for damage before each use and replace if any cracks or significant wear are visible.
