The rotary hammer can be fitted with various chisel bits
depending on the desired application. Use sharp drill

holesaws.
• For metal, use high-speed steel twist drill bits or
holesaws. Use a cutting lubricant when drilling metals.
The exceptions are cast iron and brass which should be
drilleddry.
• For masonry, such as brick, cement, cinder block, etc.,
use carbide-tipped bits rated for percussiondrilling.
