Keep the motor running while pulling the bit out of a drilled hole. This will help reduce jamming.
Make sure switch turns drill on and off.
Drilling in Wood
Holes in wood can be made with the same twist drill bits used for metal or with spade
bits. These bits should be sharp and should be pulled out frequently when drilling to
clear chips from the flutes.
Drilling in Metal
Use a cutting lubricant when drilling metals. The exceptions are cast iron and brass
which should be drilled dry. The cutting lubricants that work best are sulfurized cutting
oil or lard oil.
Drilling in Masonry
Use carbide tipped masonry bits. Refer to Drilling section. Keep even force on the drill
but not so much that you crack the brittle material. A smooth, even flow of dust indicates
the proper drilling rate.
