Drill cleanly and efficiently into concrete and masonry with the Dewalt DT60343-QZ hollow extraction hammer drill bit. By removing dust directly through the hollow body into your connected extractor while drilling, you maintain a cleaner work environment and eliminate the need for manual hole cleaning. The 4-cutter carbide tip ensures precise positioning, reduced friction, and exceptional durability, even in reinforced concrete. Featuring an 18 mm diameter, a 250 mm working length, and an overall length of 370 mm, it is ideal for anchor installations. The SDS-plus shank delivers a secure fit and maximum impact energy transfer from your rotary hammer.
