There are many kinds of bits used in industry. The  drill bitscan be classified according to different drilling methods, which are fried dough twist drill and percussion drill. These two kinds of drill bits are the most basic form.

Here is a summary

Characteristics of percussion drill

Fried dough twist drill

Fried dough twist drill and percussion drill what is different?

What are fried dough twist drill and percussion drill?

Percussion drills rely on rotation and impact force to work. A single impact is very slight, but an impact frequency of more than 40000 times per minute can produce a continuous force. It can be used for natural stone or concrete. When the percussion drill works, there is an adjustment knob at the bit chuck, which can adjust the two modes of ordinary electric hand drill and percussion drill. However, the impact drill uses the gears on the inner shaft to beat each other to achieve the impact effect, but the impact force is far less than that of the electric hammer. It is not suitable for drilling reinforced concrete. Among them, there is a kind of diamond coring bit, which can meet the needs of more and more coring applications on the job site. This high-quality dry diamond coring bit can be used in granite, marble and other dry and wet applications. Of course, there is another kind of drill, which is suitable for dry drilling. Diamond coring bit is used to drill various stones, usually used to drill pipe holes on decorative stones. It is equipped with manual drilling machine and desktop drilling machine, which are driven by motor. However, this kind of bit needs to use water to cool the bit to prolong its service life

Its features: the tool adopts corrugated design, with good sharpness; Vacuum brazing protection section is adopted for the appearance of the substrate to improve the drilling speed and smooth the roughness of drilling in the drilling; It can be used both dry and wet.

Fried dough twist drill is a tool for drilling the round hole of a workpiece by means of its rotary cutting with a fixed axis. It is named for its shape of fried dough twist and its shape is like twist. Spiral grooves have 2 grooves, 3 grooves or more, but 2 grooves are the most common. Fried dough twist can be used in manual and electric handheld drilling tools or drilling machines, milling machines, lathes and even machining centers. The drill bit material is generally high-speed tool steel or cemented carbide.

Diamond V-shaped hollow bit with high drilling accuracy. It is used for drilling all kinds of stone materials, specially processing small diameter holes, equipped with manual drilling machine or drilling machine. Some of the best fried dough twist drill is made of high quality diamond material. It is suitable for core taking of marble stone, ceramic brick and wall materials. The utility model has the advantages of high processing efficiency, fast drilling speed, smooth drilling without seamless, long service life and good chip removal performance. Excellent performance and durability, mainly used for angle grinder.

Fried dough twist drill is based on fried dough twist drill to make it suitable for various kinds of work requirements. The shape can be understood. Twist drill is a simple handle + spiral, and percussion drill is mostly handle + spiral + flat head.

What are fried dough twist drill and percussion drill?

Fried dough twist drill is usually made of metal. Construction drill is actually impact drill, which is mostly used for drilling concrete, masonry and other holes.
