Differences Between Worm Drive and Circular Saw

The right kind of saw will mean everything to anyone starting the sawyer occupation. This is because information technology’south the link between his effectiveness and lack thereof. At that place are two main types of saws, the worm drive, and the circular saw. In this commodity, we explore the differences between the two to help you find the correct saw.

What is a Worm Drive?

A worm drive is a type of circular saw whose motor is attached at the rear finish giving them a sleek contour that is useful for working in tight spaces.  They are named afterward the spiral gear that powers the motor. This pattern produces first-class torque which is rotational speed and therefore greater cutting ability.

Power is driven through 2 gears that are prepare 90 degrees apart. The engine produces more rotational force (torque) but fewer Rotations per Minute (RPM) of virtually iv,500. The positioning of the motor at the rear makes this saw longer than the regular saws.

The extra metal required for the worm drive, still, significantly increases the weight of the saw. This tin can lead to fatigue in the hands and shoulders on long workdays. The worm bulldoze saw is thus heavier, more powerful, and more expensive than a regular saw. They are more efficient amongst professionals that need actress cut power but non as useful to home improvement enthusiasts.

Information technology has larger gear teeth with more than loading capacity which provides more than power.

Traditionally, worm drives have been blade-left while the direct drives have been blade-right.

The torque provided is enough to saw through wet lumber and concrete, making the worm drive platonic for framing and major renovation jobs.

The first to be made was Skilsaw in the mid-1920s by founder Edmond Michel.

 Characteristics of Worm Drive

  • Great torque
  • Large cutting capacity
  • Faster and more reliable cuts
  • The cuts are more accurate
  • The in-line motor is balanced for accurate cuts
  • Heavy
  • More than expensive

What is a Circular Saw?

The circular saw is a blazon of saw whose motor is attached at its side, besides the blade. This makes the saw shorter and wider.  They are too commonly known equally sidewinders or direct-drive saws. Round saws were invented in the 18th century and were normally used in sawmills in the US in the mid-19th century. They may be handheld or mounted onto a machine. They are particularly designed for the fabric intended to be cut. In woodwork, they are specifically made for making rip-cuts, cross-cuts, or both.

They have a less involved internal mechanical design and rely on spur gear to power the blade. It is thus a lightweight saw but produces less torque and maximum cutting power. They are lighter, more portable, and less expensive saws. The off-balance setting of the motor also makes it harder for them to make accurate cuts. For anyone who capitalizes on cost-effectiveness and portability than power and accuracy such as amateur woodworkers, they are a fine tool.

The side mounting allows the saw blade to exist driven directly without actress gears. This office is known as direct bulldoze. The saw has a good speed of upwards to 6,000 RPMS (because the saw works without actress gears) just less torque.

They have good ripping and cutting ability.

Characteristics of Circular Saw

  • Lightweight and easily portable
  • Easy to use
  • Inexpensive
  • Lop-sided placement of the motor is not best for accurate cuts
  • Lower torque and maximum cut capacity
  • Slower cutting speed

Similarities between Worm Drive and Circular Saw

  • Both saw blades are fabricated of types of steel depending on the material they are designed to cut.
  • Both have cordless versions that use batteries.
  • Both can make rip-cuts and cross-cuts.

Differences betwixt Warm Drive and Circular Saw


The worm bulldoze has a higher torque than the round saw. This is considering it is more powerful and durable which makes it able to handle high energy. The worm drive is also designed to take larger teeth, thus enabling greater loading chapters than the round saw.


The worm drive is heavier (from the extra metal used and the housing design) than the circular saw. The worm drive is thus less portable than the circular bulldoze.


The worm drive has less speed with fewer Revolutions per Minute of 4,500 than the circular saw which is higher in speed, making six,000 or more RPMs. This divergence, however, balances with the torque.

Bract Orientation

Generally, the worm drive has blades on the left (blade-left) while the round saw is bract-right. The blade-left worm drive gives left-handed users ameliorate sight-line visibility. The blade-right round saw, on the other hand, gives ameliorate cut-line visibility to right-handed users.


As a result of the positioning of the motor, the worm drive is longer and narrower than the circular bulldoze which is shorter and wider.


The worm drive is more than expensive as information technology’due south heavier and more than powerful than the circular saw.

Accuracy of cuts

The worm drive is best for accurate cuts. Due to the lop-sided placement of the motor, the circular saw is non all-time for accurate cuts.

Worm Drive vs. Round Saw: Conclusion

The worm drive and circular saw are both skillful saws. If you are looking for a cost-effective and portable saw, you have it in the circular saw. If you are looking for ability and accurateness, then you take it in the worm drive. Wondering which 1 to pick between the two? Information technology all depends on you. Whichever choice you brand, you can’t go wrong every bit they are both ideal.
