OPERATION
CARE IN DRILLING
Twist drills are brittle and will break if enough bending stress is applied. To avoid
stress on the drill bit, try extending your index finger along the side of the drill*
housing V ith your middle finger on the trigger. Remember guide the tool, don’t
force it! Should the tool become overheated., run it free of any load at maximum
speed. The drill will cool faster by running it without toad.
DRILLING IN METAL
Use a cutting lubricant when drilling metals. The exceptions are cast iron and brass
whi'-h should be drilled dry. The cutting lubricant that works best is sulphurized
cutting oil. Aluminum is best drilled with kerosene.
DRILLING IN WOOD
Holes In wood can be made with the same twist drills used for metal. These bits
may overheat unless pulled out frequently to clear
Chios from the flutes» For
larger holes, use Power Drill Wood Bits with a shank size that will fit your drill's
chuck. Work that is apt to splinter should be backed up with a block of wood. Let
up on the pressure just before the tip cuts through, this will give a good clean hole.
