Bench Grinder Buying Guide & FAQ
Things To Consider When Buying A Bench Grinder
Buying a bench grinder is definitely going to be a considered purchase and not something you should be lightly jumping into. Before you do go ahead and take the plunge, it’s essential that you first identify and recognize your needs, set out a pre-determined budget and consider any reputable brands that you might feel more comfortable purchasing from. With power tools, we wouldn’t encourage you to take any risks. While some lesser-known brands may well be up to the task, make sure that you have thoroughly done your research first or at the very least, had a good read of our comprehensive guide. While the most expensive product isn’t necessarily always the best, this is one category of product where you absolutely need to be confident that what you are purchasing are quality manufactured goods.
Bench Grinder Uses
While you might think that the purpose of a bench grinder is pretty self-explanatory, the clue is in the name, after all, don’t just limit yourself to that view. You might be surprised to learn just how versatile that bench grinder really is and if you are looking for extra ways to justify the expenditure, we’ve got a handful of practical uses that your versatile grinder is more than up to the job of fulfilling. It’s not just about shaping and sharpening metal, it’s also about cutting and cleaning it too. Just think about all the practical applications as well as the skilled trades those benefits can be utilized in?
From building furniture and leveling out joints, to removing group and raising nail heads, your grinder can be used for all kinds of Carpentry and Flooring needs. Need to remove some old paintwork? Well that grinder you’ve just invested in can also be used instead to sandpaper only get this, it’s faster and more efficient! Need to cut outworn away pipes for a DIY home plumbing job? Again, with a craftsman bench grinder in your man cave, workshop or garage, you really can be a Plumbing Pro. You might save yourself a heap of money in the long run just by saving call outs of all kinds of professionals you usually have to enlist the help of around your home. There really are so many practical applications that you will find yourself using that new bench grinder for, you’ll wonder how you ever used to manage without one.
Choosing The Right Grinding Wheel
If you have already been through our top ten product recommendations in the best bench grinder category, then you will have noted that they all fall into one of two categories in terms of their size. Either 6-inch or 8-inch. That measurement refers to the size of the actual grinding wheel and generally speaking, an 8-inch s used more by the industrial or professional trades.
Besides the grinder size, the other thing you need to decide upon is what type of wheel to go for. So that you can make that decision easier, we’re going to quickly run through the various types but roughly speaking, the kind of wheel you go for should be related to the sort of materials you intend using the grinder predominantly for. Materials which are hard and more brittle will require a softer grade wheel while conversely, softer materials respond better to a harder grade wheel. Below are the most common types of wheel you are likely to come across.
Straight Wheel - Overall this is the most common type and is suitable for application just as sharpening chisels and other tools. They can come in various sizes and are appropriate for surface grinding.
Cylinder Wheel - This is a hollow style wheel, and it has limitations in that it can only be used with vertical or horizontal bench grinders. Typically there are much larger in size and are great if you need to produce a flat surface.
Tapered Wheel - With this type of wheel, it tapers off towards the edge and therefore can be useful for working on more delicate projects.
Other Types Of Grinders
Besides the considerations which we’ve already laid out above, there are a couple of other key types of grinding machines that it’s worth being aware of. These are a Die Grinder and an Angle Grinder. The former is a hand-held rotary style tool that you can use to grind, sand and polish. The latter is yet again, a portable tool and is great for grinding and polishing. These tools, being much smaller in size, are better suited to more delicate or intricately detailed work plus they also have the other big advantage of being far more portable. What they do lack, however, is the power and versatility that comes with a bench grader so if you do have a workshop or space for a DIY station at home, a bench grinder is definitely going to give you more value and versatility overall.
Bench Grinder FAQ
Q: Does my grinder require any maintenance?
A: As a general rule of thumb, your bench grinder will require the same kind of maintenance as any of your power tools do. Additionally, it will have one very special requirement, and that’s the wheel dressing. Wheel dressing is important to reduce wobble and to expose fresh grit so that you can continue to get the best results from your purchase. It’s always a good idea to routinely check your bench grinder and to ensure that it is always stowed away safely plus remove any dust and debris each time you’ve used your machine.
Q: How often should I replace my wheel?
A: The regularity with which you might need to change your wheel is related to how often you use your bench grinder and the kinds of materials that you are also more commonly grinding. As with any tool that features moving parts, besides being routinely maintained, they will need to be replaced if they are beginning to wear out. A visible check of the state of your wheel should alert you as to whether it’s time to get it changed.
Q: What safety issues might I experience using my grinder?
A: The principal safety issues to be aware of are flying sparks and debris. That’s why you will note that most of the professional quality units we reviewed in our Buyers Guide come fitted with safety eye shields and protective spark guards.
