7. Keep the motor running when pulling the bit back out of a drilled
hole. This will help prevent jamming.
8. With variable speed drills there is no need to center punch
the point to be drilled. Use a slow speed to start the hole and
accelerate by squeezing the trigger harder when the hole is deep
enough to drill without the bit skipping out. Operate at full on after
starting the bit.
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 chips
from the flutes. For larger holes, use low speed wood bits. Work that
is likely to splinter should be backed up with a block of wood.
Drilling in Metals
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 sulphurized cutting oil or lard oil; bacon grease will also
serve the purpose.
Operation as a Screwdriver
Select the desired speed/torque range using the dual range gear
shifter on the top of tool to match the speed and torque to the
planned operation.
Insert the desired fastener accessory into the chuck as you would
any drill bit. Make a few practice runs in scrap or unseen areas to
determine the proper position of the clutch collar.
