Best Die Grinders 2018 – Reviews & Buyer’s Guide
Die grinders are very powerful tools, which have been traditionally used to grind metal. Nonetheless, you don't have to be working with metal. The best die grinders have unbelievable RPM speeds, and their incredible power can be used in a wide variety of ways. Some of the uses that make these tools a must-have include:
Getting Rid of Rust
A die grinder is a must-have tool when you are working with older steel or iron machinery. Since rust forms when iron is exposed to moisture and oxygen, whenever your iron or steel tools are exposed, they may rust over time. a die grinder can effectively remove rust using an array of accessories.
Finishing up Stainless Steel Projects
When you're working with stainless steel, you want your final product to look as professionally done as possible. As such, you need to smoothen and polish the steel. This can be done by moving the grinder as gently a possible over the welded bits, so that they match the rest of the steel.
When you're repairing your vehicle for collision repairs, you probably have to strip off the pain to work on the bare metal. Die grinders can come in handy especially when you want to get rid of paint in the smaller areas that may be hard to reach using a sander. Alternatively, to remover the metal sheet that needs replacing, you can install a cutting wheel onto the grinder.
Finishing Non-Metal Surfaces
Although die grinders are often used for metal works, they can be used to smooth anything else down. In fact, many woodworkers like to use die grinders to smooth out wooden surfaces to produce a more professional finish. You can substitute sanding for die grinders to hasten the process. Die grinders will also work perfectly on plastic surfaces too!
Die Grinder Buyer's Guide
Unlike larger grinders, die grinders are meant detail-oriented work, and are not intended for rough cutting. they are among the smallest types of grinders, and their high speed and wide variety of tips make them suitable for adding details and finishing up a work piece. Since the tools are rather simple, there are just a few options available to choose from. These options come in terms of the type of tip you need on the die grinder. Here are some of the things you should consider when buying a die grinder.
Die grinder vs. Cutoff tool
Many die grinders are usually sold as cutoff tools that come with extras such as the installation of a guard, and a fibrous cutoff wheel. The cutoff wheel enables the grinder to cut metal bars and tubing. This means that if you buy a die grinder instead of a cutoff tool, you can convert it for cutting metal, and tubing, with a shield that protects you from metal sparks. The only difference between a cutoff tool and a die grinder is the shield.
Die grinders are often designed to allow the user to control the speed, though they are commonly used at full speed. However, for those looking to cut softer materials like plastic and wood, the variable speed will come in handy, as it prevents over-cutting or even the destruction of the workpiece.
Right vs. Straight Angle
Conventional grinders are straight, where the tool rotates perpendicular to the length of the tool. In recent models, manufacturers introduced the right angle die grinders, with some coming built at 30 degrees. In some types of operations, the angled head is much easier to hold, but all angles to have their place. A right-angle grinder is best suited for grinding wheels that mount on to a shaft, and still has a variety of types of tips that can be mounted on it.
Cordless vs. Pneumatic
Just like with other power tools, cordless die grinders are now entering the market, offering users great portability and ease of use. Although cordless die grinders are usually longer than the pneumatic ones, not having to drag the power cord or air hose around allows them to reach into more areas, some of which pneumatic die grinders simply can't.
Cordless grinders are often used on remote jobsites by contractors than by people working in a shop. Of course, the benefit of working off a battery isn't apparent when working in a shop with power available throughout. Moreover, cordless die grinders require stopping to change the battery periodically.
