Extended-Length Carbide-Tipped Drill Bits with Coolant Holes
Also known as gun drills, use these bits to drill long, straight holes. A hole in the bit allows coolant to be channeled through the tool for more efficient chip evacuation. More wear resistant than cobalt steel and high-speed steel, these carbide-tipped bits maintain a sharper, harder edge at high temperatures for excellent performance on abrasive material.

SDS-Max-Shank Hollow Masonry Drill Bits for Dust Containment
When connected to a vacuum, these hollow bits can suck up concrete dust while drilling to help meet OSHA standards for silica dust exposure. They can also be used to clean out holes for installing adhesive anchors. The SDS-Max shank has three deep slots and two shallow slots for use with SDS-Max-drive rotary hammers. They cannot be used with SDS-Plus-drive rotary hammers.
