شفرة القص بالحافة المجزأة (DW47452HP) من (Dewalt) قطر (115MM) و بسماكة (7MM) و قطر دائرة تثبيت (22.2MM)

It’s designed to cut through masonry materials such as brick, concrete, block, and stone. The segmented rim helps manage heat and debris, enabling efficient cutting of hard substrates.

Segmented rim blades have gaps (segments) between the cutting teeth, which helps with faster cutting, better cooling, and reduced binding in tough materials. Continuous rim blades are typically smoother for cutting ceramics or tiles but may heat up more quickly on masonry cuts. The segmented design is optimized for masonry and concrete in this Dewalt blade.

Check the blade’s diameter and arbor (hub) size to match your grinder. Also verify the grinder’s maximum RPM rating to ensure it’s within the blade’s operating speed. Size and compatibility details are typically listed on the product page or packaging; use that information to confirm fit for your tool.

1) Ensure your grinder is unplugged or powered off. 2) Confirm the blade size and arbor match your grinder. 3) Install the blade with the label facing up and tighten the nut securely. 4) Reinstall the guard for protection. 5) Start at a steady speed and avoid side pressure to prevent binding. 6) Let the blade cool if it becomes hot and inspect for damage after use. 7) Use appropriate PPE (eye protection, hearing protection, gloves, and a dust mask if cutting masonry).

Wear eye protection, hearing protection, gloves, and a dust mask or respirator when cutting masonry. Ensure proper guard installation, avoid kickback by not forcing the blade, and never use the blade if damaged or cracked. Maintain a stable stance and keep hands away from the cutting area.

Inspect the blade before each use for cracks, missing segments, or warping. Clean off dust and debris after use, store in a dry place, and avoid dropping or striking the blade. If you notice any significant wear or damage, replace the blade to ensure safe and effective performance.

Look for cracks in the segments, missing teeth, noticeable dullness, or an unusual wobble when spinning. If you see any damage or a drop in cutting efficiency, replace the blade to avoid poor cuts or safety hazards.
