شفرات القص المجزاة الليزرية (DX3781) من (Dewalt) قطر (230mm) و بحجم تجويف (22.2 mm) الخاصة بالخرسانة

Key specs include a 230 mm diameter (D230), a 22.2 mm bore (D230XBS22.2), segmented laser-cut segments for concrete/masonry, and a design focused on reduced vibration and smoother cuts. It’s built for robust cutting performance on hard materials.

It’s optimized for concrete and masonry, including pavers, brick, blocks, and other concrete-based surfaces.

Steps:1) Ensure the tool is powered off and unplugged or the battery is removed. 2) Verify the blade’s bore matches your tool’s arbor (22.2 mm in this case) and that the rotation direction is correct. 3) Mount the blade onto the arbor, align the washer and nut, and tighten securely with a proper tool. 4) Recheck clearance and ensure the blade is seated flat before use. 5) Replace the guard or shield as required by your tool.

Wear appropriate PPE (eye protection, gloves, hearing protection). Use a stable cutting platform, keep hands away from the blade edge, and avoid binding by applying steady, moderate pressure. Inspect the blade for cracks or damage before each use and replace if any damage is found. Do not exceed the tool’s rated RPM.

Compared to other concrete segmented blades on Fepy, the DX3781 emphasizes reinforced laser-cut segments for reduced vibration and an anti-kickback design, which can translate to smoother cuts and longer life in tough concrete work.

Use cases include cutting concrete slabs, pavers, masonry blocks, bricks, and other concrete-based materials in construction, remodeling, or site preparation projects where a fast, clean cut is required.

Yes. Always ensure correct bore size and proper arbor fit, keep the cutting edge clean, avoid overheating by avoiding prolonged continuous cuts, and allow the blade to cool if you’re making long cuts. Use a steady feed rate, check for material binding, and store the blade in a protected case when not in use.

Follow general grinding/cutting safety: wear eye protection, gloves, hearing protection, and a dust mask if cutting dry. Ensure guards are in place, the workpiece is secured, and the tool is on a stable surface. Inspect for cracks or damage before use and never cut materials outside the blade’s intended scope.

Lifespan depends on material hardness, feed rate, and usage. The reinforced laser-cut segments are designed for longer life under concrete and masonry cutting, but actual counts vary with job conditions. Regular inspection and proper cooling (where applicable) help maximize blade life.

Given its reinforced design, segmented construction, and anti-vibration features, it offers strong value for professional concrete cutting tasks on masonry and paving projects.
