Bench Grinders BUYING GUIDE
Motor power is one of the most important considerations to take into account when purchasing a bench grinder. However, the level or power you purchase depends on the type of work you want to do with your bench grinder. Bench grinders with more horsepower are more capable of tackling tough jobs for longer periods of time. Higher horsepower models also tend to last longer overall. Most models feature with a quarter or half horsepower motor, and this speed is adequate for most users. If you need more power, most 8-inch bench grinders feature more powerful motors. For even more power, consider purchasing an industrial bench grinder.
The types and varieties of wheels you can use with your bench grinder is another important consideration in your decision. Think about the types of projects you want to perform with your bench grinder and consider whether the model you choose is compatible with the types of wheels needed for that project. A bench grinder is no use to you if you can’t use the right wheels. Most people who purchase bench grinders use fine grit, wire brush, coarse and buffing wheels, all of which cover the needs of most projects.
Sharpening tools and other projects that require bench grinders can involve a lot of moving parts and dangerous situations. Safety should be an essential priority for anyone looking to buy one of these tools. Consider the type of safety features your bench grinder provides. Things like spark guards and eye shields are safety features that can protect your from bodily harm while using your bench grinder. While some bench grinders offer safety in the form of additional attachments, it’s much safer to buy a bench grinder with built-in safety features.
Most bench grinders on the market offer a slew of different features that aren’t consistent among all the models. These additional features provide a greater experience in some way and how important some of these are depends entirely on your personal preferences. Things like tool trays, mounting holes, anti-vibration features and water cooling trays all provide an extra level of convenience and functionality to the bench grinder you buy. If these features are important to you, consider purchasing one with more additional features, but be aware that you might pay a premium for them.
For under $50, you can buy a budget bench grinder. These bench grinders typically offer quarter horsepower motors and 6-inch wheels, if not smaller. Bench grinders in this price range are perfect for beginners and hobbyists. In the $50-$100 range, you can buy a bench grinder that offers most of the features you’ll need. These units are usually more powerful than budget models and tend to offer more additional features. For more than $100, you can buy a premium bench grinder. If you’re looking for an industrial bench grinder, you’ll most likely pay more than $100. These premium models offer more attachments and safety features than most other bench grinders on the market.
