An arbor on a circular saw is a metal rod that is connected to the blade of the saw. The arbor is typically threaded on one end, allowing the saw blade to be secured to it with a nut. The other end of the arbor has a pilot hole which corresponds to the hole in the center of the saw blade.
This hole is used to hold the blade in place while it is being used. In some models, the arbor is also used to adjust the depth of the cut or to attach dado blades. Safety is the primary concern when operating a circular saw and the arbor is designed to help keep the blades secure and locked in place.
What size arbor do I need?
When selecting an arbor, the size you should purchase will depend on the size of the blade you are looking to use. A standard circular saw blade typically ranges in size from 4-1/2” to about 10” in diameter.
Generally, the arbor size should match the size of the blade, but some blades will require an arbor slightly bigger than the blade’s diameter. A chart showing the typical arbor sizes for various blades is available from most hardware stores.
In addition to the size of the blade, you should also consider the power output of your saw motor. Overworking the saw motor by using a too heavily loaded blade could cause overheating and premature motor failure.
If the saw motor does not have sufficient power or torque to spin the blade at the proper speed, you may need a larger arbor than what is recommended by the blade manufacturer.
In most cases, it is best to purchase an arbor that is a little larger than the blade size to ensure proper performance of the saw and blade. If you are unsure of what size arbor to purchase, it is best to contact the saw manufacturer and discuss your needs with them.
How do you measure an arbor?
Measuring an arbor can be a tricky task and will require some special tools. To measure an arbor accurately and properly, you will need a set of calipers, a tape measure and some form of level tool (e. g.
spirit level).
To measure the diameter of an arbor, use a pair of calipers to set the distance between the two measuring points. Ensure a snug fit and take several measurements to guarantee accuracy.
To measure the length of the arbor, use a tape measure to determine the distance between the two ends of the arbor. If you want to make sure the arbor is perfectly vertical, you can use a level tool to check for any deviations.
For anything else related to the measurements, use your own judgment and consult with someone more knowledgeable about arbors. Following these steps should help you accurately measure an arbor in no time.
How do you remove arbor bolts?
Removing arbor bolts can be a tricky task, especially if they have been in place for some time. The easiest way to remove them is to use a drill and a few hand tools. First, make sure the drill is set to reverse.
Put the drill bit into the center of the screw, then drill at a slow speed until it is a few millimeters deep. Be careful not to drill too deep, or else the wood may catch and break the bit. Once the pilot hole is in place, use a pair of pliers to grip the head of the arbor bolt and begin gently twisting in a counterclockwise motion.
If the screw will not budge, try spraying a small amount of lubricant or penetrative oil over it to help loosen the rust. With a few moments of patience, the arbor bolt should become loose. Be careful to not strip the head of the screw as you remove it.
Once the arbor bolt is out, use the correct size drill bit and tap the threads to ensure a proper level of fitting for the new arbor bolt.
What are different types of bolt heads?
Bolt heads come in a variety of shapes and sizes that are suited to different applications. The most common types of bolts are hex head bolts, carriage bolts, pan head bolts, button head bolts, hex flange bolts, truss head bolts, oval head bolts, and socket head cap screws.
Hex Head Bolts have a six-sided head that is intended for an adjustable wrench (or spanner in British English) and are commonly used in the construction industry, most notably for wood construction. Carriage Bolts have a domed head and a square shoulder underneath which fits into the hole and prevents the bolt from turning when the nut is tightened.
Pan Head Bolts have a shallow, rounded head that is designed to prevent any snag points when used with fragile materials. Button Head Bolts have a rounded dome-shaped head and are commonly used in applications where a low-profile head is called for.
Hex Flange Bolts feature a washer style flange built in to the head of the bolt and are meant to create a secure connection when bolted together with a nut.
Truss Head Bolts have a large, flat top surface with a rounded edge and provide higher resistance to tampering when compared to other types of bolts. Oval Head Bolts have a low-profile, tear drop shaped head and are commonly used for aesthetic purposes.
Socket Head Cap Screws are internally threaded fasteners with a hexagonal drive hole, frequently used in various motorsport and industrial applications.
What is the Arbor size on a Dewalt miter saw?
The Arbor size on a Dewalt miter saw can vary depending on the model. Generally, the size for the majority of miter saws will be 5/8-inches. There are, however, specialty saws that come with a larger arbor size.
For example, the Dewalt DWS780 sliding compound miter saw model has a 1-inch arbor. If you own an older Dewalt miter saw model or have a replacement saw, it is best to double-check the arbor size before finding the correct blades to use.
You can do this by measuring the inside diameter of the arbor hole on the blade.
What blade comes with DWS780?
The DEWALT DWS780 12-inch Double Bevel Compound Miter Saw comes with a high quality carbide-tipped blade. This blade is designed to cut through a variety of materials quickly and efficiently, while leaving a clean and precise finish.
The blade is precision-ground with an optimized cutting angle to provide smooth cutting without producing heat or causing the material to chip. It is also made with a durable construction to ensure long-term use.

What is the difference between the Dewalt 779 and 780?
The Dewalt 779 and 780 routers are both corded, variable speed, fixed base routers with 1⁄4″ and 1⁄2″ collets. However, there are several key differences between them.
The 779 is a 12 amp motor, with a soft start feature that reduces start-up torque for increased bit and motor life. It also has a variable speed range of 8,000-24,000 RPM and a 12 Position Cone-Lock™ depth adjustment for precise adjustments.
The 779 also has removable handles for greater control over smaller projects.
On the other hand, the 780 is a 15 amp motor, without the soft start feature, and a variable speed range of 10,000-21,000 RPM. It also has a convenient depth knob that allows depth to be easily adjusted with finger control while keeping a firm grip on the router.
The 780 also has two handles mounted behind the router motor, allowing for a wider range of movement and improved control with larger projects.
Overall, the 779 is better suited for precision work, while the 780 is more powerful, making it well-suited for larger projects where more power is required.
What is saw blade arbor size?
The saw blade arbor size is a term used to describe the size of the hole in the center of a circular saw blade. This hole allows the blade to be mounted onto a compatible arbor or spindle that is connected to the saw motor.
The arbor size is typically expressed as a number and is typically preceded by the letter “A” or “D. ” The number indicates the diameter of the arbor hole in either inches or millimeters. For example, a blade with an “A7” arbor size has a 7/8-inch diameter arbor hole.
Other common arbor sizes are “A10” for a 1-inch arbor hole, and “A4” for a 5/8-inch arbor hole. Additionally, many table saws use a “D10” arbor, which is a 10 mm diameter arbor hole. It’s important to match the arbor size of the saw blade to the size of the arbor of the saw motor in order for the blade to fit properly.
Some saws are sold with a variety of arbors and some arbors can be replaced to allow the saw to accommodate different arbor size blades.
What is a gullet on a saw blade?
A gullet is a space between the teeth on a saw blade. It allows for smoother, less aggressive cutting action than would be possible without the gullet. The gullet also allows for easier chip disposal and improved cutting efficiency.
The size of the gullet varies depending on the application, but is typically deeper for a more aggressive cut and shallower for a more finished cut. As the blade rotates in the cut, it forces chips ahead of it, out of the cut along the length of the saw blade.
The size of the gullet allows the blade to have sufficient clearance to clear the material and avoid tight spots. In general, the deeper the gullet, the more aggressive the cut and larger the chip size, while the shallower gullet requires less power since there is less material to move away from the blade.
