Last month, my daughter insisted on joining her to build a dog house. Every parent wants to fulfill their kid’s wish, and so was I.
I have collected all the necessary equipment to spend quality time with my beloved kid. But I can’t decide to pick a worm drive or hypoid.
Chainsaws are big and powerful that makes them unsuitable to be used at home. This is the reason I had to pick any of these tools.
I visited tool stores, researched a lot, and finally took a decision to go as per the project requirement.
A professional knows the differences between worm drive and hypoid since they are familiar with these tools. But people like me get confused when it comes to deciding to pick any of the devices.
That is why I decided to share my experience and wrote this worm drive vs hypoid article.
What is a Hypoid Saw?
The saw structure is similar to hypoid gear, which is why it receives this name. Hypoid gears consist of the non-intersecting and unparalleled axes. This gear has a 200:1 gear ratio, and it is an ideal option when a task requires high RPM and massive torque. This is the reason it is called the hypoid saw.
Hypoid saws provide the best RPM, and it is possible because the blade, gear set, and motor are positioned following an angle. Its efficiency is pretty high (80% – 90%).
What is Worm Drive Circular Saw?
The worm gear is used in the worm drive circular saw. A gear wheel and straightened metal are the significant parts of this saw. The unique feature of the worm drive circular saw is – adjustable efficiency. At 300:1 gear ratio, these saws are 49% efficient, while at 5:1 gear ratio, they are 90% efficient. This is why they can be used in a wide range of applications.
Worm Drive vs Hypoid – What are the Key Differences?
Both tools are unique in their characteristics. Let’s learn the key differences between worm drive circular saw and hypoid from below.
1# Gear System
In a worm drive, the blade receives power through a worm gear. Using a worm-wheel and worm, a gearbox of worm drive is manufactured, and both components are perpendicularly positioned with each other.
When a worm drive turns 360°, the worm wheel progresses only 1 tooth.
Hypoid saw, on the other hand, works similarly to a spiral bevel gear. Hypoid saw axis and meshing gear axis are miss-aligned.
In fact, hypoid gear axes are non-intersect. Since hypoid saw gear is offset from the center of the equipment, distinctive outlines are possible with this tool, and it also can accommodate a more massive diameter shaft.
Hypoid saw, and worm drive circular saw’s teeth are different. Hypoid saw consists of helical teeth. The truth is, these teeth are cross-breed of a worm drive and bevel gear.
Hypoid saw offers many contact points because of the large pitch surface. As a result, energy transfer happens from any angles without any trouble. Moreover, hypoid saws come with large pinion diameters, which make them compatible with torque demanding projects. These saws have a long lifespan and don’t create much sound to disturb you and your neighbor.
Compared to hypoid saws, worm drive circular saws are noisy. But they are also good at delivering excellent results in torque demanding jobs.
Sealed motor system – this is one of the best features of hypoid saws. Changing the gear oil is unnecessary due to the feature.
On the other hand, replacing the gear oil is a mandatory task in worm drive circular saws. When this saw runs, it discharges microscopic components into the oil that affects the system’s overall lubrication.
Additionally, most hypoid saws are made of hardened-steel while bronze is used to manufacture worm drive, which implies that hypoid saws are much more durable than worm drive.
Although both tools’ gearing system is quite similar, hypoid saws transfer less power than worm drives.
Although maintenance cost is less in Hypoid saws because of the sealed motor design, it has drawbacks. Since gear oil is unreplaceable in hypoid saws, the motor life will decrease when the oil loses lubrication properties.
In contrast, you can change the gear oil of the worm drive circular saw, and thus the motor delivers long term service.
At this point, both tools have similarities. Both devices are ideal for torque demanding jobs, which means you can cut through any hardwood or plywood with both hypoid saws and worm drive circular saws.
Additionally, the cut line is visible since the blade is positioned on the left side.
And both tools are efficient enough to handle heavy-duty tasks with extended weight.
Worm Drive or Hypoid Saw – Which one to Choose?
With the above discussion, you have understood that worm drive and hypoid saw are made for handling different situations.
Worm drive circular saws are best for overhead because of their lightweight feature. However, you can use it for angle cuts too. If maneuverability is the requirement of your project, don’t hesitate to pick a worm drive.
On the other side, hypoid saws less maintenance, unreplaceable oil change feature makes them suitable for industrial works. Moreover, they are a bit heavy compared to worm drive, and for this reason, industrial and construction sites use them for cutting plywood or hardwood.
Honestly, with both tools’ unique characteristics, you can’t say one type of device is better than another. It would be best if you chose a tool that is best suited for your project.
Generally, most worm drive circular saw blades are designed left-hand-oriented. Due to this orientation, the saw weight puts pressure on top of the material used, making it easier to stabilize when cutting.
Worm drive circular saws are durable. They consist of larger teeth that make them eligible for more loading capacity. For this reason, a user can handle challenging projects with it.
Hypoid saws are great power tools for a wide range of cutting projects and jobs. Hypoid saws come with extreme power and torque, and that is why they are good options for handling large DIY or home improvement projects.
Why do we use power tools? We all want to accomplish any project with the best efficiency, productivity, and less hassle.
Hopefully, this worm drive vs hypoid article will help you pick the right tool based on your project. Also, it is always essential to wear safety gear when working with a power tool. Never try to handle a project without wearing safety gear.
Which power tool have you chosen between worm drive and hypoid? Also, let us know what safety precautions you have taken. Feel free to comment.
