  operation, press the variable speed switch again  
  and release it.
 f Based on the different applications, turn around

Drilling in metal
Start drilling with slow speed and increase to full power while 
applying firm pressure on the tool. A smooth even flow of 
metal chips indicates the drilling metals. The exceptions are 
cast iron and brass which should be drilled dry.
Note: Large [5/16” (8 mm) to 1/2” (13 mm)] holes in steel 
can be made easier if a pilot hole [5/32” (4 mm) to 3/16”  
(5 mm)] is drilled first.
Drilling in wood
Start drilling with slow speed and increase to full power 
while applying firm pressure on the tool. Holes in wood 
can be made with the same twist drills used for metal. 
These bits may overheat unless pulled out frequently to 
clear chips from the flutes. Work that is apt to splinter 
should be backed up with a block of wood.
Drilling in masonry
When drilling in masonry, use carbide-tipped bits rated for
Impact drilling and be certain that the bits are sharp. Use a
constant and firm force on the tool to drill most effectively.  
A smooth, even flow of dust indicates the proper drilling rate.
