Here are some important things to consider before buying a bench grinder:

 

– Power & Speed
When considering which product to go for, think about whether your use of the machine will be on light tasks or heavy tasks requiring a bigger more powerful/faster motor. Bench grinders typically have an RPM range from 2000 RPM to 4000 and up. It varies from model to model, but the best advise is to choose one with adjustable speed settings so whatever you’re doing you can simply change the speed to suit your needs.

 

– Grinding Wheel type
The type of grinding wheel that comes installed on the machine is important (however it can be changed out later). The different wheels are for different jobs and materials. Some materials will call for a more coarse wheel and some others will need it to be less coarse for a finer result. Some models even come with medium and coarse wheels so you can swap them yourself depending on what the task at hand calls for.

 

– Sturdy & Reliable
A good machine should have reviews from consumers that reflect its quality and reliability. It’s important that it has a solid build quality so it can stand up to being used often without breaking down. It’s also a good idea to look for one that features a cast iron base as this prevents wobbling while grinding.

 

– Built in light
Even if your work space is well-lit, it’s a bonus if you can find a machine that comes with an LED light built in. This helps to illuminate the area you’re working in specifically, helping with more precise and effective work, it’s also a safety feature.

 

– Warranty
Ideally you should pick a tool which is a good brand and you know you can rely on. But even then there is some chance of encountering problems, so it is a good idea to check out the warranty from the manufacturer. The best idea would be to buy your machine from a manufacturer that offers a warranty of one year or more, this way you can have peace of mind that if something goes wrong you’re covered.

 

Now that you have some more information let’s take a closer look:

Some Handy Uses:

 

 

You can use a bench grinder to sharpen your drill bits…

If you’re using your drill press a lot, chances are you have noticed some wear on your drill bits. Thankfully using a bench grinder it’s very easy to get them back in great shape! There are a few other ways to do it like using a file etc but they’re not as effective. Drill bits can be quite expensive to replace so having the ability to re-sharpen them is really useful.

Follow these tips and you’ll be good to go again in no time:

 

– First remember to wear gloves & safety glasses

– Hold the drill bit so that its cutting face is paralleled to the grinding wheel.

– Carefully allow the bit to make contact with the wheel, keeping it held straight and sturdy. Ensure that you don’t remove an excessive amount of metal that you don’t need.

– While doing this if the bit is in contact for too long it can heat up and weaken it, so take it off to dip it in water frequently.

– Once you have one cutting edge sharp, rotate it to take care of the other side.

Finally, let it sit in water if it needs to cool off, then put it back in your drill press for a test!
