أداة (لقمة) مثقاب (Dewalt) نوع (SDS+) قياس (20MMX250MMX300MM)

Diameter: 20 mm; Working length: 250 mm; Overall length: 300 mm; Tip: high-grade carbide; Construction: high-strength steel; Shank: SDS+; Designed for drilling in concrete, masonry, and brick; suitable for use with SDS+ drills and hammers.

Designed for concrete, masonry, brick, and other masonry materials. It is compatible with Dewalt SDS+ drills and other SDS+ hammer drills, as well as standard corded or cordless rotary drills with appropriate SDS+ adapters.

Insert the bit into an SDS+ chuck or compatible adapter, ensure it is securely seated, and use hammer mode for masonry drilling. Drill with steady pressure, avoid binding, and withdraw occasionally to clear debris. The SDS+ shank enables simple, one-handed installation and removal.

The bit uses a carbide tip for wear resistance and heat tolerance, and its design includes concave pocket flutes to reduce heat buildup. Drilling in short bursts and allowing cooling time between passes also helps prolong bit life.

The 250 mm working length provides extra reach for deeper holes, while the 300 mm overall length offers additional clearance and control in challenging drilling scenarios, such as into thick masonry or when anchoring deeper fixtures.

Both are 20 mm SDS+ bits designed for concrete and masonry. The Bosch option typically emphasizes its own carbide tip durability and Bosch engineering, while the Dewalt bit emphasizes its visibility, carbide tip wear resistance, and long reach.

Both offer comparable diameter and length for large-diameter masonry drilling. Makita often highlights its own carbide tip geometry and manufacturing tolerances, while Dewalt focuses on tip durability and SDS+ shank reliability.

Ideal for drilling large-diameter holes in concrete, brick, and block to install anchors, conduit, plumbing and wiring passes, or heavy-duty fasteners where deep, clean holes are required.

Use hammer mode with a steady, controlled feed. Start at a slow speed and increase gradually as the bit bites into the material. Avoid excessive pressure to prevent bit binding. Periodically withdraw the bit to clear dust and let the bit cool if it becomes hot.

Wear safety glasses or a face shield, hearing protection, and gloves. secure the workpiece, ensure the drill is in good working order, and keep hands away from the rotating bit. Work in a well-ventilated area and use a dust mask or extractor when drilling masonry to control dust.

Consider the durability of the carbide tip, the long reach provided by the 250 mm working length and 300 mm overall length, and how it compares to other brands on Fepy. If the product doesn’t meet expectations, check Fepy’s return options for unused items within the applicable window to ensure you get value for money.
