Why are worm drive saws better?
6 min read
Asked by: Randy Jacobs
Worm drive saws offer more durability and power because they have larger teeth which have a more loading capacity than regular circular saws. This feature enables the user to handle loads with high shock. It can handle tougher projects because it has great muscle to pitch cut.
What are the advantages of a worm drive saw?
Advantages of a Worm Drive Circular Saw
The longer distance between the handle and the blade extends your reach while making a cut, which is helpful for crosscutting sheet goods. A worm drive also has larger gear teeth with more load-carrying capacity than a direct drive, which provides more power but also adds weight.
What makes a worm drive saw ideal for framing?
The motor is in line with the blade, delivering enough torque to carve up wet lumber or saw through concrete, which makes a worm drive ideal for framing or major renovation jobs. With the handle farther back, a user can better resist kickback and steer the 16-pound saw through long rips.
Who should use a worm drive saw?
As worm drive saws provide a higher torque than circular saws, it’s best used for jobs that require immense cutting power – such as cutting through knotty wood, and also for plunge cuts.
Which is better Sidewinder or worm drive?
Sidewinder vs Worm Drive Torque
A worm drive saw has larger gear teeth with more load-carrying capacity than a sidewinder, offering more power and durability. It also allows the saw to handle higher shock loads. It has more muscle to plunge cut and handle tougher jobs.
What’s the difference between a worm drive and a regular circular saw?
Regular circular saws have an RPM of 6,000 or higher while worm drive saws have an RPM of not more than 4,500. This difference of RPM is however balanced when it comes to torque. Worm drive saws offer more durability and power because they have larger teeth which have a more loading capacity than regular circular saws.
Why are worm drive saws left handed?
Traditionally, all worm drive saws operated in a blade-left orientation. Furthermore, this orientation likely places the weight of the saw over the portion of the material the user wants to keep, making it easier to stabilize the saw during the cut.
Is it okay to cut wet wood with a circular saw?
If you’re cutting wet wood set the depth so that the entire gap between the teeth is clear of the board you’re cutting. This will stop your saw and cut line from getting clogged with wet saw dust.
Why is it called worm drive?
A worm drive is a gear arrangement in which a worm (which is a gear in the form of a screw) meshes with a worm wheel (which is similar in appearance to a spur gear). The two elements are also called the worm screw and worm gear.
What kind of oil goes in a worm drive saw?
Product Description. Lube-V 680W Fully Synthetic Worm Drive Saw Oil is 100% synthetic oil with viscosity grade ISO VG 680 for use in all worm drive saw brands. It has outstanding performance much better than well-known market brand such as Skil 80111.
What brand of circular saw is best?
Top 9 Circular Saws
- Makita 5007 Magnesium Circular Saw.
- DEWALT 20-Volt Circular Saw.
- SKILSAW SPT77WML-01 15-Amp Worm-Drive Circular Saw.
- CRAFTSMAN 15-Amp Circular Saw.
- Milwaukee 2830-20 Circular Saw.
- SKILSAW 5280-01 Circular Saw With Laser Guide.
- Makita SH02R1 12-Volt Max CXT Cordless Circular Saw Kit.
Is rear handle circular saw better?
Because of the placement of the motor, Rear Handle Circular Saws get a heck of a lot more torque than a standard Sidewinder Circ Saw. Sidewinders get more RPM’s, but the torque and power beats speed when you’re cutting into hardwoods with a Worm Drive (rear handle) saw.
What is a hypoid circular saw?
With a hypoid circular saw, the motor sits at a right angle to the blade, with the motor near the rear of the tool, and the blade being on the left side of the motor.
What is a hypoid gear set?
A hypoid is a type of spiral bevel gear whose axis does not intersect with the axis of the meshing gear. The shape of a hypoid gear is a revolved hyperboloid (that is, the pitch surface of the hypoid gear is a hyperbolic surface), whereas the shape of a spiral bevel gear is normally conical.
Which gear is more efficient?
Efficiency: a spur gear is more efficient if you compare it with a helical gear of the same size, because helical gears have sliding contacts between the teeth which in turns produce an axial thrust of gear shafts and generate more heat. So, more power loss and less efficiency.
Can hypoid gears be back driven?
Hypoid gears are typically used in rear-drive automobile drivetrains. A higher hypoid offset allows the gear to transmit higher torque. However increasing the hypoid offset results in reduction of mechanical efficiency and a consequent reduction in fuel economy.
Why is hypoid more suitable on commercial vehicles?
In most of commercial vehicle, single stage hypoid gears are used in the rear axles. Not only does this give a better fuel consumption: the noise level mostly is lower. Also the number of rear axle part is smaller and hence the weight of a single ratio hypoid axle will be lower than of a two stage hub reduction axle.
What is the reason for using hypoid gears in the rear axle?
Hypoid gears are not used as simple reducers, but their purpose is to redirect rotation and torque by a certain angle, commonly 90°. In case of hypoids, the second purpose of lowering the center of gravity of a vehicle body has become very important in the automotive and truck industry.
Why do hypoid gears require special lubrication?
Explanation: Hypoid gears require special lubricant because of the extreme pressure between the teeth. The sliding motion of the teeth is effective due to the use of special lubricant.
What is a hypoid diff?
Hypoid gearboxes are a type of spiral bevel gearbox, with the difference that hypoid gears have axes that are non-intersecting and not parallel. In other words, the axes of hypoid gears are offset from one another.
Is GL5 the same as hypoid?
GL-4 is suitable for hypoid gear service when they are under severe service but are without shock loading. GL-5 is suitable for hypoid gear service under severe service and shock loads and not for use in a gearbox.
Is Lucas gear oil hypoid?
Gear oils have needed improving for years, especially in the high performance industry. The Lucas SAE 80W-90 HYPOID enjoys the technology Lucas developed in making the “Lucas Heavy Duty Oil Stabilizer”, the number one supplemental oil in the heavy duty industry.
What is SAE 80W-90 hypoid gear?
GEAR OIL HYPOID SAE 80W/90 is a high-pressure gear oil that can be used wherever very high levels of stress occur, such as in cardan joints, hypoid gears etc.
Can you mix synthetic gear oil with regular?
So, in the end, conventional and synthetic oils are comprised of the same, compatible components – it’s just that the components in synthetics are much higher quality. While you can safely mix synthetic and conventional oils, you’re doing nothing more than diluting the performance of the synthetic oil.
What does GL 5 stand for?
The designation API GL-5 denotes lubricants intended for gears, particularly hypoid gears, in axles operating under various combinations of high-speed/shock load and low-speed/high-torque conditions.
