Periodically withdraw the bit to clear dust and debris for more efficient drilling and to reduce heat build-up.

Usage recommendations

For best results when drilling into reinforced concrete or dense masonry, use a hammer drill with sufficient power rating, keep the bit cool by withdrawing frequently to clear dust, and select the correct hole depth and diameter for the intended anchor or fastener.
