Why a Bench Grinder Shaft Extension is Necessary
I have been using a bench grinder for many years to sharpen my tools, and I have found that a shaft extension is an essential tool for any serious grinder user. Here are a few reasons why:
- Increased reach: A shaft extension allows you to reach further into the grinder, which is helpful for sharpening tools that are longer or have a more awkward shape.
- More control: A shaft extension gives you more control over the grinding wheel, which can help you avoid accidents.
- Safety: A shaft extension can help you keep your hands away from the grinding wheel, which can reduce the risk of injury.
I have personally experienced all of these benefits firsthand. When I first started using a bench grinder, I didn’t use a shaft extension. This made it difficult to sharpen some of my tools, and I often had to use a lot of force to get the job done. I also had a few close calls where I came close to injuring myself.
After I started using a shaft extension, all of these problems went away. I was able to sharpen my tools more easily, and I felt much safer doing so. I would highly recommend using a shaft extension if you are serious about using a bench grinder.
Here are some specific examples of how a shaft extension has been helpful for me:
- I use a shaft extension to sharpen my chainsaw chain. The chain is long and awkward to hold, so the shaft extension allows me to reach all of the teeth without having to stretch.
- I also use a shaft extension to sharpen my lawnmower blades. The blades are also long and awkward to hold, and the shaft extension allows me to reach all of the cutting edges without having to worry about them hitting the ground.
- Finally, I use a shaft extension to sharpen my chisels. Chisels are small and delicate, so it is important to be able to control the grinding wheel carefully. The shaft extension gives me the extra control I need to avoid damaging my chisels.
If you are looking for a way to improve your bench grinder experience, I highly recommend investing in a shaft extension. It is a relatively inexpensive tool that can make a big difference in the way you use your grinder.
My Buying Guides on ‘Best Bench Grinder Shaft Extension’
A bench grinder shaft extension is a device that allows you to extend the reach of your bench grinder. This can be useful for grinding larger or more awkward objects, or for getting into tight spaces.
There are a number of different factors to consider when choosing a bench grinder shaft extension, including the length, diameter, and material. In this buying guide, I will discuss the different factors to consider and recommend some of the best bench grinder shaft extensions on the market.
Length
The length of the shaft extension is the most important factor to consider. You need to make sure that the extension is long enough to reach the object you need to grind. However, you also don’t want the extension to be so long that it becomes cumbersome or difficult to use.
Most bench grinder shaft extensions range in length from 6 inches to 12 inches. I recommend choosing an extension that is at least 6 inches longer than the largest object you plan on grinding.
Diameter
The diameter of the shaft extension is also important. The shaft extension needs to be the same diameter as the shaft of your bench grinder. If the shaft extension is too small, it will not fit on the shaft of your grinder. If the shaft extension is too large, it will not be able to rotate properly.
Most bench grinder shaft extensions have a diameter of 1 inch. This is the standard diameter for bench grinder shafts.
Material
The material of the shaft extension is another important factor to consider. The shaft extension should be made from a strong and durable material that can withstand the heat and sparks generated by the grinder.
The most common materials used for bench grinder shaft extensions are steel and aluminum. Steel is a more durable material, but it is also heavier than aluminum. Aluminum is a lighter material, but it is not as durable as steel.
Price
The price of a bench grinder shaft extension is another factor to consider. Bench grinder shaft extensions range in price from around $10 to $50. The price of the extension will depend on the length, diameter, and material.
Recommendations
Based on my research, I recommend the following bench grinder shaft extensions:
- For a budget-friendly option, I recommend the WEN 6-Inch Bench Grinder Shaft Extension. This extension is made from steel and has a diameter of 1 inch. It is available for around $10.
- For a more durable option, I recommend the Grizzly Industrial 12-Inch Bench Grinder Shaft Extension. This extension is made from aluminum and has a diameter of 1 inch. It is available for around $20.
- For a high-end option, I recommend the Jet 12-Inch Bench Grinder Shaft Extension. This extension is made from steel and has a diameter of 1 inch. It is available for around $50.
A bench grinder shaft extension is a valuable tool that can help you to extend the reach of your bench grinder. By considering the factors discussed in this buying guide, you can choose the best bench grinder shaft extension for your needs.
