Drill Level
Your tool is equipped with drill level, located on top of the housing, that will allow you to accu-
rately enter the workpiece and drill in a horizontal position (Fig. 1).
USING THE LEVEL: Place the drill bit where the hole is to be drilled, position the drill so the
bubble in the level is centered between the lines, then start drilling the hole. When the bit has
entered the workpiece, check from time to time to be sure that the bit is maintaining the hori-
zontal position.
Operating Tips
You will extend the life of your bits and do neater work if you always put the bit in contact with
the work before pulling the variable-speed trigger to start the drill. During operation, hold the
tool firmly and exert light, steady pressure. Too much pressure at low speed will stall the tool.
Too little pressure will keep the bit from cutting and cause excess friction by sliding over the
surface. This can be damaging to both tool and bit.
Drilling with Variable Speed
The variable-speed feature eliminates the need for center punches in hard materials. The vari-
able-speed trigger allows you to slowly increase RPM. By using a slow starting speed, you are
able to keep the bit from "wandering". You can increase the speed by squeezing the trigger as
the bit "bites" into the work.
Drill Bits
Always inspect drill bits for excessive wear. Use only bits that are sharp and in good condition.
TWIST BITS are available with straight and reduced shanks for wood and light-duty metal
drilling. High-speed bits cut faster and last longer on hard materials.
Drilling Wood
Be certain that the workpiece is clamped or anchored firmly. Always apply pressure in a
straight line with the drill bit. Maintain enough pressure to keep the drill bit "biting".
When drilling holes in wood, twist bits can be used. Twist bits may overheat unless pulled out
frequently to clear chips from the flutes.
Use a "back-up" block of wood for work that is likely to splinter, such as thin materials.
You will drill a cleaner hole if you ease up on the pressure just before the bit breaks through
the wood. Then complete the hole from the back side.
