Wood Auger Drill Bit and metal drill bits are drill bits that are frequently used in our daily lives, so what is the difference between the two?
(1) Different materials:
{1} Black drill bits are generally used for metal drilling. The material of the drill bit is generally high-speed steel. Drill holes in general metal materials (alloy steel, non-alloy steel, cast iron, cast steel, non-ferrous metals), and use it with metalworking drill bits.

{2} Drilling holes in wooden materials requires the use of woodworking drills. Woodworking drills have a large sales volume and do not require high tool hardness. The tool materials are generally high-speed steel. There is a small point in the center of the tip of the drill bit, and the angles on both sides are relatively large, and it can even be said that there is no angle.

(2) Different drill bit designs (tip, blade, groove type, shank, etc.) structure:

{1} The iron drill is generally pointed in the middle (large force, wear resistance, and good for feeding); this structure is more labor-saving, when drilling, the force is relatively large, and the wear resistance is good for feeding.

{2}Drilling wood generally has a three-pointed blade with a high middle and low sides. Because the wood is softer, it will be drilled faster, and the cutting edges on both sides can make the drill hole even and beautiful, so it is also called a thin plate drill.

(3) Different processing methods and processes:

{1} The iron drill is directly shoveled by the cutting edge of the drill bit.

{2} The drill bit for drilling wood has 2 blades on the edge, and it is first cut off with a flat blade in the middle.
Different materials: black drill bits are generally used for metal drilling, and the drill bit material is generally high-speed steel. Drill holes in common metal materials (alloy steel bai, non-alloy steel, cast iron, cast steel, non-ferrous metals), and use metalworking drill bits.

The working principle of the electric drill is that the motor rotor of the electromagnetic rotary or electromagnetic reciprocating small-capacity motor does the magnetic cutting operation. The working device is driven by the transmission mechanism to drive the gear to increase the power of the drill, so that the drill can scrape the surface of the object and make better hole penetration. object.

Wood Auger Drill Bit and Extra Long Wood Drill Bit belong to the main hardware tools, mainly composed of an inner rotating impact body and an outer impact body.
