Bend or burn bits
Produce off-center or irregular shaped holes
When drilling large holes in metal, it is recommended that you drill with a small bit at first, then
finish with a large bit. Also, lubricate the bit with oil to improve drilling action and increase bit
life.
10.4 Driving screw
▪ For maximum performance, use good quality bits for driving screws , turn the function
mode selector on the screwdriver mode position“21”.
▪ Fix the torque setting low enough to allow a safety margin. Use a very low torque setting
when first driving small screws into soft materials. Then adjust the setting as the proper
force required is determined.
NOTE: The torque setting required depends on the item being driven. In the
case of screws, consider the size, length, and type of material.
10.5 Hammer Setting
▪ For maximum performance, use a good quality masonry bit for hammer drill, turn the
function mode selector on the impact mode position“ ”.
▪ Only use this setting to bore or drill into stone/concrete. The Hammer setting works well
when drilling/chipping into materials.
▪ The tip of tool MUST be firmly depressed for the hammer action to engage.
NOTE: Only use a masonry bit when drilling into masonry materials.
