Use high speed steel, carbide, TiN 1. coated, or specialty bits for metal
drilling.
Secure the work piece to keep it from 2. moving during the drilling operation.
To make starting the hole easier, use 3. a punch to create a dimple at the hole
center.
Unless drilling into cast iron or brass 4. use a cutting lubricant.
Start by drilling slowly to keep the bit 5. from moving away from your starting
point.
As the hole is established, increase 6. tool speed. Do not go so fast or use
so much pressure that the bit heats
up. This can damage the bit and
create an irregular hole. For hard
metal, use cutting oil to keep the bit
cool.
Since drilling in metal is a slow 7. operation, you may lock the Trigger
in the ON position to maintain a
constant speed and reduce fatigue.
When drilling large holes in metal, 8. start by drilling a smaller pilot hole,
then using a larger bit for the nal
size hole.
wood drillingUse high speed bits or bits specially 1. designed for wood drilling, such as
brad point, spade bits, forstner bits,
etc.
Secure the work piece to keep it from 2. moving during the drilling operation.
Start by drilling slowly to keep the bit 3. from moving away from your starting
point. Increase speed as the hole is
established.
To prevent or reduce “break out”
4. when the bit penetrates the work
piece, clamp a piece of scrap material
to the back of the work piece.
Do not lock the Trigger in the ON 5. position, as the bit can easily jam in
wood and the motor must be stopped
quickly.
after useTo prevent accidents, disengage
the trigger, remove the bit, and
disconnect the tool’s power supply
after use. Clean, then store the tool
indoors out of children’s reach.
