Release Time:

Jul 28,2024

Different materials: Black drill bits are generally used for drilling metal, and the drill bit material is usually high-speed steel. When drilling on general metal materials (alloy steel, non alloy steel, cast iron, cast steel, non-ferrous metals), metalworking drill bits are used in conjunction.

Drilling holes in wooden materials and using woodworking drill bits, woodworking drill bits have high cutting sales and do not require high tool hardness. The tool material is generally high-speed steel.
There is a small pointed tip at the center of the drill bit, and the angles on both sides are relatively large, even without any angle.
2. Different drill bit design structures (tip, blade, groove type, shank, etc.):
The iron drill is usually pointed in the middle. This construction is relatively labor-saving, with high drilling force and wear resistance, which is conducive to feed.
3. Drilling wood is generally a three pointed blade, with the middle higher and the sides lower. Because the wood is soft, it can be drilled faster and the edges on both sides can make the drill hole flat and beautiful, also known as thin plate drill.
