When it comes to power tools, DeWalt is a name synonymous with quality and performance. Known for their durability and reliability, DeWalt grinders are essential equipment in many toolboxes, whether for professional contractors or DIY enthusiasts. A common question among users, both seasoned and novice, revolves around the arbor size of DeWalt grinders. Specifically, do the grinders have a 5/8 or 7/8 arbor size? This article delves deep into the mechanics of these grinders, explains arbor sizes, and offers insights into choosing the right tool for your needs.
What is an Arbor and Why Does It Matter?
To appreciate the differences in arbor sizes, it’s essential to understand what an arbor is. The arbor is the part of the grinder where the grinding wheel, cutting disc, or any other attachment is mounted. It essentially connects the tool to the attachments, enabling them to rotate at high speeds.
Importance of Arbor Size:
1. Compatibility: The arbor size directly affects the type of attachments that can be used with the grinder. Using the wrong size can not only lead to inefficiency but also poses safety risks.
2. Performance: Each grinder and its attachments are designed to work optimally with specific arbor sizes, affecting performance characteristics such as speed, torque, and precision.
Understanding the common arbor sizes helps you choose the right disc or wheel, ensuring effective and safe operation of your grinder.
DeWalt Grinder Arbor Size Options
DeWalt grinders can typically accommodate a couple of different arbor sizes, primarily 5/8-inch (or 5/8-11 threaded) and 7/8-inch. The choice between these sizes often depends on the model of the grinder in question and the specific application for which the tool is intended.
5/8-Inch Arbor Size
Many of DeWalt’s angle grinders feature a 5/8-inch arbor size. This size is particularly common among standard grinding and cutting wheels compatible with the following tasks:
- Grinding metal surfaces
- Cutting through various materials such as tiles, concrete, and metal
The 5/8-inch arbor typically has a threaded design, allowing for a quick and secure attachment of grinding wheels and other accessories. This size is popular for general-purpose grinding tasks, and as a standard size in the industry, it offers a wide variety of compatible discs.
7/8-Inch Arbor Size
While less common than the 5/8-inch size, some specific DeWalt models do feature a 7/8-inch arbor. This size is often used with specific specialty wheels designed for particular grinding tasks, such as smooth cutting or more detailed work. The 7/8-inch arbor allows for a wider flange that helps with stability when using certain types of attachments.
Most 7/8-inch arbor attachments are often centered on specialized use cases, providing the following benefits:
Benefits of the 7/8-Inch Arbor:
1. Stability: A wider attachment provides greater balance and lower vibrations during operation.
2. Compatibility with Specialty Tools: While not as widely used as the 5/8-inch arbor, specific grinding and cutting wheels requiring a 7/8-inch arbor can enhance precision and performance.
Key Differences Between 5/8 and 7/8 Arbor Sizes
When choosing between a 5/8 or 7/8 arbor grinder, there are several factors to consider. Here, we highlight the key differences to aid in your decision-making process.
1. Performance
The performance of the grinder can vary based on the arbor size. Generally speaking:
- 5/8-inch Arbor: Commonly found in standard angle grinders, providing versatility for multiple applications.
- 7/8-inch Arbor: Used for specific tasks that might require extra stability and less vibration.
2. Compatibility with Accessories
Your choice of arbor size will affect the type of attachments you can use:
- 5/8-inch wheels are widely available and can perform various functions.
- 7/8-inch wheels, while limiting in compatibility, can provide increased performance in specialized applications.
3. Availability of Attachments
Due to the popularity of the 5/8-inch arbor, attachments are more readily available in local hardware stores and online. The 7/8-inch arbor may offer fewer options but can be invaluable for specific tools.

Choosing the Right Arbor Size for Your Needs
Selecting the right arbor size for your DeWalt grinder involves more than just the number; it pertains to your needs, comfort level, and specific applications. Here’s how to make the right choice:
1. Evaluate Your Projects

However, if you have experience and know the specific application where a 7/8-inch is needed, then choosing that option could increase the quality of your work.
3. Safety First
Finally, always adhere to safety guidelines, taking care to use the correct size attachments for your grinder. Mismatched sizes can lead to improper operation and potential hazards.
Conclusion
Ultimately, when determining if DeWalt grinders have a 5/8 or 7/8 arbor, the answer largely depends on the specific model you select. Understanding the implications of arbor sizes aids users in making informed decisions that not only enhance performance but also prioritize safety. Whether you choose the widely used 5/8-inch or the more specialized 7/8-inch, DeWalt grinders offer distinguished performance, demonstrating the brand’s commitment to quality craftsmanship.

What arbor sizes are available for DeWalt grinders?
DeWalt grinders typically come with two main arbor sizes: 5/8-inch and 7/8-inch. The standard size for most of their angle grinders is 5/8-inch, which accommodates a wide variety of grinding wheels and attachments. However, some models, particularly those designed for specific applications or regions, may support the 7/8-inch arbor size.
When selecting a DeWalt grinder, it is essential to check the specifications of the model you are interested in. This will ensure that you’re aware of the arbor size, as it will affect the compatibility with different grinding wheels and accessories. Knowing this will help you avoid any potential issues when outfitting your grinder with the right tools.
How can I determine the arbor size on my DeWalt grinder?
To determine the arbor size of your DeWalt grinder, you can refer to the user manual that came with the tool. The manual will typically include specifications such as the arbor size, model number, and compatible accessories. If you don’t have the manual, you can also check the information on the DeWalt website or reach out to their customer service for assistance.
Another way to measure the arbor size is to look directly at the spindle of the grinder. You can do this by removing any attachments or wheels and measuring the diameter of the spindle’s threaded area. This measurement will give you the arbor size, confirming whether it is 5/8-inch or 7/8-inch.
Are DeWalt grinders compatible with aftermarket attachments?
Yes, DeWalt grinders are generally compatible with a variety of aftermarket attachments, provided that they conform to the same arbor size as the tool. If your DeWalt grinder has a 5/8-inch arbor, you can use grinding wheels, cut-off wheels, and other accessories designed for that size. The same applies to the 7/8-inch arbor; just make sure to match the size appropriately.
However, it is crucial to ensure that any aftermarket attachments are of high quality and suitable for the intended application. Low-quality or improperly sized attachments can lead to safety hazards or reduced performance. Always verify the specifications and user reviews before making a purchase to ensure compatibility and safety.

This can not only diminish the performance of the tool but also pose significant safety risks during operation.
If you find yourself needing to use a specific accessory with a different arbor size, consider purchasing an adapter. Adapters can allow you to fit a 7/8-inch attachment onto a 5/8-inch arbor, but keep in mind that this can alter the tool’s performance and stability. Always consult the manufacturer’s guidelines before using adapters, as they may not be suitable for all applications.
What types of accessories can I use with my DeWalt grinder?
DeWalt grinders are versatile tools that can accommodate a variety of accessories, depending on the intended use. Common attachments include grinding wheels, cut-off wheels, flap discs, and polishing pads. Each attachment serves a specific purpose, whether it be grinding metal, cutting through materials, or polishing surfaces, allowing you to tackle a broad range of projects.
When selecting accessories for your DeWalt grinder, always ensure that they match the calibrated arbor size and are designed for the specific type of material you will be working with. Additionally, it is essential to choose appropriate RPM ratings that align with the specifications provided by DeWalt to ensure safe and effective operation.
Do DeWalt grinders come with a warranty?
Yes, DeWalt grinders typically come with a limited warranty, which offers protection against defects in materials and workmanship. The warranty period may vary depending on the model and the specific terms outlined by DeWalt. Generally, most power tools, including grinders, have a warranty that lasts for three years, along with a 90-day money-back guarantee.
To make the most of your warranty, keep your proof of purchase and the original packaging if possible. Should you encounter any issues with your DeWalt grinder, you can contact DeWalt customer service or visit an authorized service center for assistance. Make sure to familiarize yourself with the warranty’s terms to understand how to address any concerns effectively.
