What kind of drill should be used for drilling wood drill bits?

The drilled iron is generally a middle tip (large force, wear resistance is favorable for feeding);

The drill wood is generally a three-pointed blade, and the middle and high sides are low (the wood is soft, so that the drill is faster, and the cutting edges on both sides can also make the drill hole flush and beautiful, also called thin plate drill).

There are many differences. For example: different materials; different bit design structure (tip, blade, groove, handle, etc.); processing methods are different.

1. The Drill bits bladed product is not use for people under 18 years.
2. The item is only use for industrial cutting  not hazardous article.
