How to Choose The Best Bench Grinder – The Beginner’s Guide
Here are some points you can consider while choosing the best bench grinder.
1. Types of Grinders
Did you know?There are 2 common types of bench grinders that functions differently.
First is the die grinder. This is a hand-held rotary power tool that helps you grind objects, including sand and plastics. Next is the angle grinder. This hand-held power tool is normally used for polishing and grinding.
The former is smaller than the latter is preferable for more detailed work. As always, the best type depends on what you are working on.
2. 6-inch or 8-inch
You might have noticed that I used the term 6-inch and 8-inch a lot in the previous section. This refers to the sizes of the actual grinding wheels of the bench grinders.
6-inch is mostly used at home for light works while 8-inch is mostly used by professionals for industrial applications.
3. Type of Wheels
The wheel is equally important as the type when it comes to bench grinders. Some of the most common wheel types are:
- Straight wheel – most suitable for surface grinding & sharpening chisels
- Cylinder wheel – used with vertical or horizontal bench grinders. They help produce flat surfaces.
- Tapered wheel – most suitable for delicate works such as grinding threads or tapered wheel.
4. Bench Grinder Uses
Bench grinder is a versatile tool that can complete many works. So, it’s best if you can define the scope of your job first, before buying one. Read carefully on what each bench grinder is best for.
Bench grinders are commonly used for carpentry, plumbing, sharpening, and even flooring.
5. Bench Grinder Motor
You can say the motor is the heart of the bench grinder. Without it, a bench grinder can’t function at all.
The motor comes in different horsepower (hp) size. This hp affects the revolutions per minute (rpm) of each grinding wheel. Bigger rpm means faster work done, especially when you’re dealing with thick metals.
However, there’s also the slow speed bench grinder, which reduces built-up of heat. They complete several tasks that require specific specifications.
6. Grit Types
Aluminum oxide, silicon carbide, and ceramic. Those are the 3 most common types of grit types.
Aluminum oxide grit is used for general purpose applications. They can be used on both high and low carbon steel.
Silicon carbide grid provides a nice polished surface as a finishing grit. They are normally used on steels.
Ceramic grit is the newest of them all. The good point is that ceramic is never goes dull, it only fractures into sharper pieces over time. Thus, saving money on having to resurface your wheels.
Price of a bench grinder normally reflect on its quality and features. Though that might not be the case every time.
The bench grinders in the market ranges from around $60 up to $250.
The best tip I can give is to decide on your budget and read the reviews and features of each bench grinder carefully. Only then you can decide on which bench grinder to buy.
The selection process might be tiring and challenging. Nonetheless, it will be worth it when you got the right bench grinder.
Do consider the reviews and buying tips above and follow your guts. Every person has their own definition of best bench grinder after all. I hope this guide is helpful for you. Good Luck!
