SDS, or slotted drive system, bits are masonry bits designed for concrete drilling that provide a long service life. The carbide tips are durable making them more resistant to extreme loads. The shank has two sets of grooves that fit into the hammer drill collar and enhance the drilling torque and hammering energy of the tool. The flute section of the spiral facilitates the removal of dust as the hole is drilled, as the head and carbide tip work to break up concrete and hard materials.
Before drilling always check the integrity of your carbide tip and connection. Use lubrication to allow the bit shank to slide into the chuck by applying a small amount to the grooves.
