Tool Tips
DRILLING WOOD OR PLASTIC
Do not drill into wood with dust extraction
system mounted. Wood chips are typically too
large and will clog the dust channel.
If backing block is not used,
ease up on the pressure just
before the bit breaks through the wood to
avoid splintering. Complete the hole from the
opposite side immediately after the point
breaks through. If bit binds, reverse the
drilling operation to help remove the bit from
the work.
DRILLING METAL
Do not drill into metal with
the dust extraction system
mounted. Hot metal chips can self-ignite or
ignite parts of the dust extraction system.
