The battery life of a cordless rotary tool depends on several factors, including the type of battery, the tool's power settings, and the specific tasks being performed. Most cordless rotary tools use lithium-ion batteries, which are known for their efficiency and longer lifespan compared to older battery types like nickel-cadmium. Typically, a fully charged lithium-ion battery in a cordless rotary tool can last anywhere from 30 minutes to 2 hours of continuous use. The actual duration depends on the battery's capacity, measured in ampere-hours (Ah). For example, a 1.5 Ah battery might provide around 30 to 45 minutes of runtime, while a 3.0 Ah battery could last up to 1.5 to 2 hours under similar conditions. The tool's power settings also play a crucial role. Using the tool at higher speeds or for more demanding tasks, such as cutting or grinding, will drain the battery faster than lighter tasks like sanding or polishing. Additionally, the efficiency of the motor and the overall design of the tool can impact battery consumption. Environmental factors, such as temperature, can also affect battery performance. Extreme cold or heat can reduce the effective runtime of the battery. To maximize battery life, it's advisable to follow best practices such as fully charging the battery before use, avoiding complete discharges, and storing the battery in a cool, dry place when not in use. Some models come with interchangeable batteries, allowing users to swap out a depleted battery for a fully charged one, minimizing downtime. In summary, while the battery life of a cordless rotary tool can vary, understanding the factors that influence it can help users optimize performance and plan for efficient tool usage.

Yes, you can generally use attachments from different brands on your cordless rotary tool, but there are a few considerations to keep in mind. Most rotary tools, regardless of brand, are designed with a standard collet size, typically 1/8 inch, which allows for compatibility with a wide range of attachments and accessories from various manufacturers. This standardization means that as long as the attachment fits the collet size of your tool, it should work. However, there are exceptions and factors to consider: 1. **Collet Size**: Ensure that the attachment's shank size matches the collet size of your rotary tool. Some tools come with multiple collet sizes or adapters to accommodate different shank sizes. 2. **Attachment Type**: Some specialized attachments, like certain cutting guides or sanding drums, may require specific adapters or mounts that are proprietary to a brand. Check if the attachment requires any special fittings. 3. **Power and Speed Compatibility**: Ensure that your tool's power and speed settings are suitable for the attachment. Some attachments are designed for specific speed ranges and using them outside these ranges can lead to suboptimal performance or damage. 4. **Quality and Fit**: Even if an attachment fits, the quality and fit can vary between brands. It's advisable to use reputable brands to ensure safety and performance. 5. **Warranty and Safety**: Using non-brand attachments might void the warranty of your tool. Always prioritize safety and check the manufacturer's guidelines. In summary, while cross-brand compatibility is often possible, always verify the fit, compatibility, and safety to ensure optimal performance and avoid damage to your tool or attachments.
