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 trigger. During the oper ation, 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 trigger controlled variable speed feature will eliminate the need for center punches in hard materials. The variable speed trigger allows you to slowly increase RPM. By using a slow starting speed, you are able to keep
material is soft, drill only 2/3 the proper length. If it is hard, drill the entire length.
Second, unclamp the pieces and drill the second hole the same diameter as the screw shank in the first or top piece of wood.
Third, if flat head screw is used, countersink the hole to make the screw flush with the surface. Then, simply apply even pressure when driving the screw. The screw shank clearance hole in the first piece allows the screw head to pull the pieces tightly together.
The adjustable screw drill accessory will do all of these oper ations quickly and easily. Screw drills are available for screw sizes No. 6, 8, 10 and 12.
the bit from “wander nig”. You can increase the speed as the bit “bites” into the work by squeezing the trigger.
DRIVING WITH VARIABLE SPEED Variable speed drills will double as a power screwdriver by using a screwdriver bit in the drill mode. The technique is to start slowly, increasing the speed as the screw runs down. Set the screw snug yl by slowing to a stop. Prior to driving screws, pilot and clearance holes should be drilled.
FASTENING WITH SCREWS This procedure shown in (Fig. 12) will enable you to fasten ma terials together with your Cordless Drill/Screwdriver without stripping, splitting or separating the material.
