Product Details

This Bosch round hammer drill bit is designed to deliver 4X life when compared to standard masonry bits. It features an asymmetric diamond-ground carbide tip for precise starts and less bit walking. Milled U-flutes with deep-cut spirals help provide fast drilling in block, masonry, and concrete. The 3-flat shank helps provide aggressive gripping power.
