bits may get extremely hot during operation. Small

bits of broken material may damage barehands.

The hammerdrill can be fitted with different bits depending

on the desired application. Use sharp drill bits only.

Bit Reccomendations

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.
