Five pits: it means that the number of grooves at the drill handle of electric hammer is five pits, which are divided into three keyways and two steel ball grooves, and are suitable for five pits electric hammer. This kind of drill is generally used on heavy electric hammers.
In fact, there are several differences:
1: Sikeng is the longest collocation on the market now. There are some small places in the five pits where drills will not be installed.
2. The five pits are generally used on large electric hammers, above 38, because the large electric hammers have large torsion, and the stress structure of the five pits is relatively more reasonable.
Question 2: What do the four pits in the high-power four-pit electric hammer mean? Four pits refer to the tail shape of the drill bit.
This four pits are made in China. It's nonsense to say that high-power products are all nonsense. Imports are all two pits and two grooves, and high-power ones are all two pits and three grooves, or five pits.
Question 3: Is the five-pit electric hammer faster than the four-pit electric hammer 100? It means that the number of slots at the drill handle of the electric hammer is four pits, which are divided into two keyways and two steel ball slots, and are used on the four-pit electric hammer. This kind of drill is generally used on medium-sized electric hammers.
Five pits: it means that the number of grooves at the drill handle of electric hammer is five pits, which are divided into three keyways and two steel ball grooves. It is suitable for five pits electric hammer. This kind of drill is generally used on heavy electric hammers.
Wukeng is a patent of Bosch. You have to buy a Bosch patent to produce this kind of electric hammer. Four pits are everywhere, and every family can produce.

2. The five pits are generally used on large electric hammers, above 38, because the large electric hammers have large torsion, and the stress structure of the five pits is relatively more reasonable.
Question 4: What's the difference between a four-pit electric hammer and a five-pit electric hammer? "Four pits" should mean that there are four spirals on the drill bit of the electric hammer, just like four pits, so it is vividly called "four pits electric hammer". The same is true of Wukeng.
Bigger than normal.
Question 5: What is a four-pit four-slot, two-pit double-slot electric hammer? What is the difference? No, there is no universal drill. A drill bit includes a tool holder (1) with a tip with two cutting blades (5, 5') located on a main plane (c-c), and the cutting blades (5, 5') have short central cutting edges oriented on a second plane (e-e). The cutting edge forms a point-like central cutting edge for entering the workpiece, thus centering the drill bit. Two chip removal grooves (6, 6') are arranged on the tool holder, and the chip removal grooves (6, 6') extend from the tip to the bottom. On any cross section along the tool holder, the chip removal grooves are located at radially opposite positions to each other on the pipeline plane, which extends at 90 degrees with the same blade plane (F-F) of two blades on both sides of the pipeline, and the tool holder has the maximum rigidity in this plane. The orientation of the second plane (e-e) of the central cutting edge makes an angle of about 90 degrees with the plane of the edge or the main rigid direction (f-f) of the bottom end of the tool holder.
Question 6: What do you mean by the four pits of the impact drill? It means that the combination of brick and impact drill is four-sided, and there is a pit on each side, so it is called four pits. There are two pits and two grooves.
Question 7: What are four pits, five pits and four pits of electric hammer? It means that the number of grooves at the drill handle of electric hammer is four pits, which are divided into two keyways and two steel ball grooves. It is applied to four-pit electric hammer. This kind of drill is generally used on medium-sized electric hammers.
Five pits: it means that the number of grooves at the drill handle of electric hammer is five pits, which are divided into three keyways and two steel ball grooves, and are suitable for five pits electric hammer. This kind of drill is generally used on heavy electric hammers.
