Flat chisel Makita D-34213-10 SDS‑MAX 25×400 mm, pack of 10

Flat chisel Makita D-34213-10 SDS‑MAX 25×400 mm is a 10‑piece pack of replacement chisels engineered for use with SDS‑MAX rotary hammers. Each chisel features a straight, flat blade profile and a shank designed to fit SDS‑MAX tool holders, providing consistent cutting edge geometry for efficient removal of concrete, masonry and similar materials. The 25×400 mm dimensions balance reach and leverage for medium‑duty demolition and chiselling tasks, while the multi‑pack format ensures quick replacement on job sites or during extended projects.

Advantages

The chisels offer uniform hardness and edge shape across all ten pieces, reducing downtime by providing spare tools that maintain performance when a working tip becomes worn. The SDS‑MAX shank design ensures secure retention and fast tool changes in compatible rotary hammers. The 25 mm blade width provides a controlled removal profile suitable for both breaking and levelling operations in concrete and masonry. Supplied as a pack of 10, the set is practical for professionals and DIY users who require multiple identical chisels for continuous work.

How to use

Insert the chisel shank into the SDS‑MAX tool holder and ensure it locks securely before starting the rotary hammer. Use the flat blade to strike or pry material with steady, controlled movements, keeping the tool aligned with the work surface. Adjust hammer mode and power settings on the rotary hammer to match the material and task; use lower impact settings for delicate removal and higher settings for heavy demolition. Replace a chisel when the cutting edge becomes excessively rounded, chipped, or shortened to maintain efficient material removal.

Usage recommendations

For safe and effective operation, wear appropriate personal protective equipment including eye protection, hearing protection and gloves. Keep the chisel tip clean and free of debris to avoid premature wear, and store unused chisels in a dry place to prevent corrosion. Check that the rotary hammer selected is rated for SDS‑MAX accessories and use the correct handling technique to avoid excessive bending or side loading of the chisel.
