Factors to Consider Before Buying a Bench Grinder for Woodturning

Choosing the right bench grinder for your woodturning needs requires careful consideration of several factors.

Grinder Speed

The speed at which a bench grinder operates is crucial when it comes to sharpening woodturning tools. A slow speed bench grinder, typically running at 1725 RPM, is the best choice for sharpening and maintaining your tools. High-speed grinders can heat up your tools too quickly, causing them to lose temper.

Wheel Material

The type of wheel material you choose for your bench grinder will also impact your results. The most common materials for bench grinder wheels are aluminum oxide and silicon carbide. Aluminum oxide is a general-purpose material that works well for most woodturning applications. Silicon carbide is a more abrasive material that is ideal for shaping and sharpening harder materials.

Wheel Size

Another factor to consider is the size of the wheels. Bench grinders come in two standard sizes – 6 inches and 8 inches. The size of the wheels will impact the size of the tools you can sharpen on the grinder. If you are sharpening small tools, a 6-inch grinder may be sufficient, but if you are sharpening larger tools, an 8-inch grinder may be more appropriate.

Vibration

Vibration is another important factor to consider when purchasing a bench grinder for woodturning. A grinder that vibrates excessively can make it difficult to get a precise, sharp edge on your tools and can also cause fatigue during extended use. When shopping for a grinder, look for models with vibration-damping technology, such as balanced wheels, to minimize vibration and ensure stable results.

Safety

Safety should always be a top priority when working with power tools. When shopping for a bench grinder, look for models with features such as eye shields, adjustable tool rests, and emergency stop buttons. These features will help ensure your safety while using the grinder and prevent accidents from occurring.

Bench Grinder with Accessory Jigs vs. Complete Sharpening Systems

A bench grinder can be paired with sharpening jigs to ensure great results. But if you don’t want to go through the hassle of buying separate lathe tools & accessories that may not be designed to work together, you should buy a complete sharpening system. These systems typically include everything you need for sharpening and maintaining your tools, making them a convenient and cost-effective option.

Power

The power of a bench grinder is measured in watts, and the higher the power, the faster the grinder will run. If you plan to sharpen larger tools, you will need a grinder with a higher power output. On the other hand, if you only plan to sharpen small tools, a grinder with a lower power output may be sufficient.

Bearing Type

Bench grinders can have either sealed or open bearings. Sealed bearings are better for heavy-duty use and have a longer lifespan, while open bearings are easier to replace if they fail. Consider the type of use you plan for your grinder when making your decision.

Noise Level

Some bench grinders can be quite loud, which can be a problem if you plan to use your grinder in a shared workspace or in close proximity to others. Look for grinders with low noise levels, or invest in hearing protection if necessary.

Ease of Use

Consider the ease of use of a grinder when making your decision. Features such as adjustable tool rest, eye shields, and emergency stop buttons can make a big difference.

Cost

Finally, consider the cost of the grinder. Bench grinders can range from less than $50 to over $500. So it’s important to determine your budget and find a grinder that fits both your needs and your budget.

Frequently Asked Questions

Do I need a variable-speed bench grinder? 

Whether you need a variable-speed bench grinder depends on your specific grinding needs and preferences. Variable-speed grinders allow for precise control and customization, which can be useful for delicate or detailed grinding tasks. However, if you only plan on using your grinder for sharpening lathe tools, a fixed-speed grinder may be sufficient.

Should I get an 8-inch or 6-inch bench grinder?

Generally speaking, 8-inch grinders are better for sharpening lathe tools, as they provide more power and speed for efficient grinding. But they are typically heavier and take up more space, which may not be ideal if you have a limited workspace. On the other hand, smaller 6-inch grinders are more compact and lighter but may not have the power or speed to handle heavy-duty sharpening tasks.
