Operation

1) Hammer drilling operation

When drilling in concrete, granite, tile, etc., press the button on the c mark side fully. Be sure to use a tungsten-carbide tipped bit. Do not apply more pressure when the hole becomes clogged with chips or particles. Instead, run the tool a t an idle, then remove the bit partially from the hole. By repeating this several times, the hole will be cleaned out.

2)Drilling operation

When drilling in wood, metal or plastic materials, press the button on the mark side fully. Generally, select higher speeds for smaller diameter bits and lower speeds for larger diameter bits.

0 Drilling in wood

When drilling in wood, best results are obtained with wood drills equipped with a guide screw. The guide screw makes drilling easier by pulling the bit into the work- piece.

Drilling in metal

To prevent the bit from slipping when starting a hole, make an indentation with a centerpunch and hammer a t the point to be drilled. Place the point of the bit in the indentation and start drilling. Use a cutting lubricant when drilling metals. The excep- tions are iron and brass which should be drilled dry.
