4. Drilling operation
When drilling in wood, use the front auger. These front screws can pierce the wood naturally,
without putting pressure on the tool.
When drilling in metal, prevent the drill from slipping, use an awl and hammer to pierce a
mark. And then use the piercing tools that pierce on the mark.
Use cutting lubricant when drilling in metal. But dry drilled in steel and brass.
Warning: Excessive pressure will not accelerate drilling speed, but will damage the drill tip. It
is bad for the working of the tool and will reduce the number of tools.
The tool / bit will be with great force while you are drilling through the workpiece. Therefore,
reduce the pressure and be more careful when the bit goes to pierce the workpiece.
When the workpiece is very small, use a vise or other clamping tool to tighten it.
Maintenance and inspection
1) screw
Regularly check each part of the tool if the screw is loose. The loose should be tightened
promptly.
2) carbon brush
Check and replace carbon brushes regularly. When carbon brushes wear to the limits, they
should be replaced immediately. If there are two carbon brushes, they must be replaced
together. Keep the carbon brushes clean and slide freely inside the brush holder
