If you compare a hypoid or蠕蟲驅動鋸使用Sidewinder看到，您可以清楚地看到差異。側壁刀片位於右側，電動機位於左側。雙摩爾和蝸杆驅動器在右側有電動機，左側的刀片。它們在大多數方麵都很類似。那麼，他們是如何不同的，哪一個更好？
What Is a Hypoid Saw?
Hypoid saw is named after the gear structure used in a saw. This is called the hypoid gear structure. The axes of the hypoid gear are not parallel and the two components do not intersect each other.
Although the blade spins slower than that of a sidewinder circular saw, it takes more time to bog down when performing heavy-duty cutting tasks. However, the hypoid gear system tends to create more torque, which is good for torque-demanding applications.
What Is a Worm Drive Saw?
Worm drive circular saw uses a worm gear to transmit power to the saw blade. A worm drive gear box is consisting of two components: a worm and a worm-wheel, both are mating each other from a perpendicular position.

Hypoid Saw Vs Worm Drive Circular Saw: Key Features
Like I mentioned earlier, the gearing system transmits power to the circular saw blade. In a hypoid circular saw, the mating axes of the gearing system are not aligned and do not intersect with each other. It is the gearing system uses helical teeth.
On the other hand, a worm drive circular saw uses a worm drive gear box to transmit power to the blade. The worm-wheel and the worm mate each other from a perpendicular position.
Many woodworkers say, a worm drive saw offers more power than a hypoid circular saw. However, the result can be different in different models.
The best thing about these two types of circular saws is the positions of the motor and blade. The motor is always on the right side of the blade. Hence, the cut line appears to the user more clearly. However, the experts say that these two types of saw are suitable for right-handed woodworkers, while lauding the sidewinder saw as the best one for the left-handed people.
Lubrication of the gear system is one of the most important things to keep the machine in a good condition. Besides, it helps the gearing system work well without making noise and corrosion. Likewise, hypoid and worm drive circular saw use oil to lubricate the system. The difference is one needs to change oil, whereas the other does not.
A worm drive circular saw needs oil change since the gear system throw microscope metal pieces into the oil. This contamination deprives the system from proper lubrication. Hence, you need to change oil time to time, to keep your worm drive saw operative.
On the other hand, a hypoid circular saw uses a sealed motor system. Besides, the hardened-steel gear of the hypoid circular saws is more durable. Thus, the oil stays free from contamination which means you don’t have to spend money on more oil.
Although a hypoid saw reduces your maintenance cost, they have a serious setback. As long as there are sufficient lubrication properties in the oil, the machine stays in a good condition. But, when the oil loses those properties, the motor starts to wear out.
On the other hand, in worm drive circular saws, you can change oil whenever you need. Thus, the saw stays in a good condition for a long time.

Hopefully, the similarities and differences of the two saws are now apparent to you. The mostnotable difference between hypoid saw vs worm drive circular sawis their power transmission system. Both saws are heavy-duty and suitable for torque-demanding projects in your workshop.
However, there are certain areas of work where one works better than the other. Of course, the hardened-steel construction of hypoid saws is better than the bronze construction of worm drive circular saws. Besides, a hypoid saw keeps quiet while operating, whereas a worm drive saw makes noise.
