Not directly—impact drills are different from hammer drills and hydraulic drills. Use only in tools rated for the bit type.

Carbide tips last longer, cut faster, and handle harder, more abrasive materials than steel bits.

Yes, but for tile, a spear-point or diamond bit may be better to avoid chipping.

Drill at the correct speed, apply steady pressure, and use water cooling for prolonged or deep drilling.

Not usually—carbide tips can start directly on the material, but a pilot hole can help with large-diameter drilling.

Yes—carbide tipped masonry bits handle both well, though harder concrete may require slower drilling and more cooling.

SDS and SDS-Max bits lock into special hammer drills for higher impact energy; standard shank bits fit regular chucks.

Yes, if the shank size fits your drill, though performance will be better with a hammer drill for masonry work.

Use the speed recommended in the HD-45 manual—typically lower RPMs with steady, even pressure for masonry.

Yes, for extended drilling or hard materials, water cooling reduces heat and extends bit life.

Yes, but sharpening requires a diamond grinding wheel and the correct angle—best done by a professional.

With proper use and cooling, they can last for hundreds of holes. Lifespan depends on the material, drilling speed, and maintenance.

Match the bit diameter to your intended anchor, fastener, or hole size, and ensure the shank fits the drill’s chuck or adapter.

Yes—though hitting rebar will slow progress and cause extra wear. Use rebar-cutting techniques or bits designed for both concrete and steel.

Concrete, brick, block, stone, mortar, and some tile. They’re especially effective on dense, abrasive materials.
