Bench grinders are handy tools for sharpening, sanding and a myriad of other tasks you'll have to perform while working on many do-it-yourself projects. Depending on the work being done, many tools could be classified as a bench grinder, but there are some made with home improvement in mind. Here are 4 different types of bench grinders you can use for most home projects:
1. DeWalt DW 756 or 758 Bench Grinders
The lower-priced one is the 6-inch model with enough power to meet most of your home improvement needs. At 4 amps, these grinders are quiet and run at a speed of 3,450 rpm. However, they are heavy for grinders, weighing more than 28 pounds. The DeWalt DW 758 is an 8-inch model that can be used for more heavy duty projects. It's a useful bench grinder, but you won't find any extras as with other models. You get what you need to do the job at a minimum. One thing it does have though, which is very convenient, is a wide tool rest. You can adjust these to fit any angle you want.
2. Delta GR250 Bench Grinders
This has less power than the DeWalt models but they can still run up to a speed of 3,450 rpm (the lowest speed at which it operates is 2,000 rpm). It also has a tool rest that you can adjust, but everything is preset, making it not as flexible as a Dewalt. However, it does come with accessories, like a lamp (mounted on top). It's another quiet bench grinder than runs smoothly.
3. Jet 825 Industrial Grinders
There isn't a rule against using an industrial grinder. These 8-inch grinders are heavy duty and might be worth it if you do more extensive projects than others. Jet models can transform to a 10-inch wheel using a toggle switch. Its price is competitive with other bench grinders more commonly used for home projects, such as the ones listed above. It has a 115-watt motor and operates at 3,450 rpm. The wheel guards are made of cast-iron and includes tool rests that are adjustable.
4. Ryobi 6-Inch Bench Grinder
If you're looking for the most economical option that's not a waste of money, try a Ryobi 6-inch bench grinder with a lamp. It even comes with tinted eye shields. However, the power used on this unit is low, only 2.1 amps. You can adjust the tool rests to cut at various angles. However, its top speed is 3,600 rpm, even though it uses a single motor.
Spending a little bit more money up front to buy the right bench grinder, with the speed you need and ability to adjust, may be worth your time and effort in the long run. You don't want to get frustrated by using cheaper bench grinders that just don't meet your home improvement needs.
