The Ultimate Buying Guide for the Best Bench Grinder

A bench grinder is an essential tool for individual light-duty works, professional garage shop and heavy-duty machine shops. You can sharpen metal tools and blades, shape, polish, and hone objects when and if needed with a grinder.

There are considerations you should ponder over before going finally for a bench grinder. The ultimate and right purchase of the best bench grinder calls for an informed decision. The crucial factors that you should have full knowledge on for a better deal are size, power, safety, upgrade features, and price range.

Size

So far size is involved; it refers to the size or diameter of the wheels. The general rule of the thumb is that you will require more power to run a bigger wheel. But a wheel with bigger diameter can accomplish more jobs in a shorter time as it will touch more work area than the smaller one.

So you should opt for the bigger wheel when you need to handle larger projects. There are two popular sizes for a bench grinder – 6-inch bench grinder and 8-inch bench grinder.

6-inch bench grinder

You need a 6-inch bench grinder for basic and general-purpose tasks such as sharpening, honing, and removing rust and paint. If you are an occasional user and in need of light-duty sharpening, you should only opt for a 6-inch diameter wheel. Even a professional garage owner can do away with his jobs with that.

8-inch bench grinder

But if you are a professional and in need to handle heavy-duty jobs in a machine shop, you must choose the larger 8-inch wheel grinder. It takes the upper hand as you can accomplish both the precision and heavy-weight sharpening, shaping, and sizing with that. A larger wheel spinning will cover more area and so can cut and polish faster and finer than a 6-inch one.

Motor/Power

A motor is responsible to spin the wheels to grind tools. So the power of the motor is crucial to get your purpose served. The power of motor can rise up to 1 horsepower starting from one-third horsepower depending on the degree and level of wheel spin your tasks require. You need at least one quarter horsepower capacity motor to ably run a six-inch diameter wheel. On the other hand, three-quarter to one horsepower capacity motor is advisable for an eight-inch width wheel.

Speed Range

The speed of wheel or pace of wheel spinning is very crucial as wheels tend to get slower under load. A motor with minimum power may limp or stop while faced with an average object to deal. So better to know what is the required speed your motor should spin at to accomplish certain jobs.

The common speed range is 3400-3600 rpm to cut through objects with both 6-inch and 8-inch wheels. The bigger the wheel size, the more the speed required. To tell it another way round, the heavier the tasks, the more powerful a motor required. And we know that powerful motor means increased speed range. You can opt for two following grinders featuring two motor powers.

Slow-speed

There are jobs that you can solve at a lesser speed than the low range stated above. To put it clearly, you should accomplish woodturning, carving, and removal by ordinary grinders providing as low as 1725 rpm. If you apply more speed there, the chisel used in such task may melt or be damaged by the temperature. You can do away with a two-quarter horsepower motor that can run an 8-inch wheel at the compatible speed. That type of grinder is known to be a slow-speed grinder.

Multi-speed

But if your shop or profession needs to handle both woodturning and metalworking grinding, you can opt for grinder equipped and designed with variable speed. These are obviously the expensive alternative but they will serve the purpose of three single-speed grinders – 1725 to 3600 rpm and save money in the long run.

Construction and Material

The best bench grinder cannot but be sturdy, steady, and rigid to serve your purpose accurately. Whatever jobs you want a grinder to do that requires a grinder substantially constructed. You need both expert build-up and heavy-duty materials for that. These two factors in a combination can get a grinder rid of the vibration and noise while working.

So far the material is concerned, steel and cast iron are the two alternatives the later being the high-quality one without costing more.

Addition Features and Designs

Being in the technology-driven age, it is natural to have your tools updated with the latest features and designs. They are not merely fundamental but extremely useful. Below are they that can make your grinding jobs a breeze.

  1. Guards: Wheels running at an incredible speed will surely cause the spark and metal pieces fly off to every direction. So you need spark guard and eye shield for that to protect your eyes. Any grinder will come with those be it separately or combined.
  2. Tool Trays/Rests: They should be fitted well to set the workpiece in the right angle and position to make the work comfortable and easier.
  3. LEDs Lights/ Lamp: To have a closer view of whether the work is going in the proper direction you want or need to, lights or lamps are crucial. Latest grinders come with LED lights just above the wheels and others carry a lamp on a bendable stalk.
  4. Mounting Feet: To avoid vibration and noise, you can opt for the grinders featured with rubber feet. Nowadays, grinders at any cost come with that feet.

Price Range

The price of a bench grinder depends on the requirements to get your job perfectly done. Depending on various specifications and performance of the available grinders in the market, you can categorize them in three different classes matching their costs. They go:

  • Average: The one will cost you $40-$100 and is ideal for occasional and lighter tasks like sharpening, polishing, and removing paint and rust.
  • Medium: May cost you $100-$300 and can apply for both smaller and bigger wheel. At the high end of the medium range cost, you can have a reputed brand of grinder that will help you grind, sharpen, and shape on a regular basis in your garage or workshop. You can do both light-duty and heavy-duty work with that.
  • High-end/Expensive: To get a lifetime of grinding service backed by a robust and powerful motor, additional features, and substantial construction you have to spend $300 or even more.
