9.  To prevent accidents, remove tool’s Battery 

Pack after use.  Clean, then store the 
tool indoors out of children’s reach.

Drilling in Wood

1.  Use high speed drill bits for wood drilling and 

set mode to Drilling (Model HC92B only).

2.  Start wood drilling at very low speed 

to keep the bit from slipping.  Increase 
speed as drill bit bites into wood.

3.  When drilling through holes, place a block 

or wood behind the workpiece to prevent 
ragged edges on the back side of the hole.

Drilling in Metal

1.  Use high speed drill bits for metal drilling and 

set mode to Drilling (Model HC92B only).

2.  Start metal drilling at very low speed to keep the bit 

from slipping.  Maintain the speed and pressure, 
allowing for cutting without overheating the bit.

3.  When drilling large holes in metal surfaces, use a 

small drill bit at first.  Then finish with a larger drill 
bit.  Be sure to lubricate the bit with oil to improve 
the drilling action and help increase bit life.

Drilling in Masonry (Model HC92B only)

1.  Use carbide or specialty bits for masonry drilling 

and set mode to Hammer Drilling.

2.  When drilling in walls, start with regular 

drilling and, once tile is pierced, continue 
with Hammer Drilling mode.

NOTE:

  In deep bore holes, occasionally pull 

the drill bit out to remove dust and chips.
