What does arbor size mean on a DeWalt 790 Radial Arm Saw?
The arbor size on a DeWalt 790 Radial Arm Saw refers to the diameter of the hole in the center of the saw blade that fits onto the spindle of the saw. A proper-sized arbor is crucial for ensuring that the blade is securely mounted, which directly affects the precision and safety of your cuts. For the DeWalt 790, the standard arbor size is 5/8 inch, which is common for many woodworking and industrial blades.
Using a saw blade with an incompatible arbor size can lead to poor performance, increased vibration, and even damage to the saw. It’s essential to select blades specifically designed for the 790 model meeting this arbor specification to ensure optimal cutting performance.
Why is arbor size important when choosing blades?
Arbor size is vital because it determines the compatibility of the blade with your saw. A blade with the correct arbor size will fit snugly on the spindle, allowing for better balance and reduced vibration during operation. This stability is critical, especially for making precise cuts in woodworking projects.
Conversely, using a blade with an incorrect arbor size can lead to instability, creating a safety hazard as the blade can become loose during operation. Always verify the arbor size of the blades you intend to use with your DeWalt 790 to avoid accidents and subpar cutting results.
Can I use blades with a larger or smaller arbor size on my DeWalt 790?
Using blades with a significantly larger arbor size is not feasible as they will not fit onto the spindle without adapters, which may compromise safety and performance. Although smaller diameter blades may fit with an adapter, they can lead to instability and may not be suitable for the type of cuts expected from a radial arm saw like the DeWalt 790.
To maintain the accuracy and safety of your cuts, it’s best to stick with blades specifically designed for the 5/8 inch arbor size. This ensures seamless operation and allows you to take full advantage of the saw’s capabilities, enhancing both your efficiency and the quality of your work.
What types of blades can I use with the DeWalt 790 Radial Arm Saw?
The DeWalt 790 Radial Arm Saw is versatile and can accommodate various types of blades suitable for different cutting tasks. Common options include crosscut blades, rip blades, and dado blades, each designed for specific functions and materials. A quality crosscut blade, for instance, is ideal for making clean cuts across the grain of wood.
Additionally, there are specialized blades such as plywood blades and laminate blades that can enhance the performance of your saw. When selecting blades, ensure they are compatible with the 5/8 inch arbor size of the DeWalt 790 and check the specifications to identify what works best for your project requirements.
How do I change the blade on the DeWalt 790 Radial Arm Saw?
Changing the blade on the DeWalt 790 Radial Arm Saw is a straightforward process that should be approached with caution. First, you need to unplug the saw from the power source for safety. After that, you will typically find a blade guard that must be lifted or removed to expose the blade. Make sure to wear appropriate safety gear during this process.
Once the blade is exposed, use a wrench or appropriate tool to loosen the arbor nut that secures the blade in place. Carefully remove the old blade from the arbor, and replace it with the new one, ensuring the blade is mounted correctly, typically with the teeth facing the front of the saw. Finally, tighten the arbor nut securely before swinging down the blade guard and plugging the saw back in.
What is the maximum diameter of blades that can be used on the DeWalt 790?
The DeWalt 790 Radial Arm Saw is designed to accommodate blades with a maximum diameter of 10 inches. This size is ideal for a wide range of cutting applications, allowing users to tackle both thick and thin materials efficiently. When choosing a blade, it’s essential to stick to this maximum diameter to ensure that the saw operates safely and effectively.
Using blades larger than 10 inches can pose significant risks, such as binding or kicking back during operation. Adhering to the specified maximum blade diameter helps maintain the balance and speed of the saw, which is crucial for achieving high-quality cuts.
What should I consider when selecting a blade for different materials?
When selecting a blade for different materials, it’s crucial to consider the type of cut you intend to make. For instance, hardwoods may require a blade with fewer teeth and a thicker kerf for effective cutting, while softer materials like pine can benefit from blades with more teeth to achieve smooth finishes. The tooth design and material composition of the blade will also affect performance on different materials.
Additionally, consider the RPM and feed rate of your saw when choosing a blade. A slower feed rate may be suitable for thicker materials or harder woods, while a faster rate can be utilized for thinner or softer ones. Tailoring your blade selection to your material and cutting technique will lead to better results and prolong the life of both your blade and radial arm saw.
How often should I replace the blade on my DeWalt 790?
The frequency of replacing the blade on your DeWalt 790 Radial Arm Saw depends on several factors, including the type of material being cut, frequency of use, and the quality of the blade itself. Generally, a high-quality blade used regularly for woodworking can last several months to a few years, whereas cheaper blades may dull more quickly.
Signs that it’s time to replace the blade include difficulty making clean cuts, excessive burn marks on the wood, or visible wear and damage to the teeth. Regular inspection and maintenance of your blades will help ensure that you operate at peak performance and can influence the longevity of both the blade and the saw itself.
