Recommendations for Tool Operation
• Large (8 mm to 13mm) holes in steel can be made easier if
a pilot hole (4 mm to 5mm) is drilledfirst.
• When drilling, always apply pressure in a straight line with
the bit, but do not push hard enough to stall the motor or
deflect thebit. A smooth even flow of material indicates the
proper drillingrate.
• If drilling thin material or material that is prone to splinter,
use a wood “back‑up” block to prevent damage to
theworkpiece.
