How to Choose a Grinder Tool
Size and Power
Small grinders in the 4- to 5-inch range are helpful for DIY projects and simple tasks like removing brick mortar. Larger grinders can tackle tough jobs like cutting tile or stucco. Look for a motor in the 9- to 11-amp range for these projects. If your grinder is going to see a lot of work, pay attention to comfort and ergonomic design. Quality handles and vibration control can make a difference.
Cordless grinders are less powerful but offer more mobility. If you’re working over a large surface area or you’re outside away from a power source, this option is ideal. For jobs on construction sites, look for an electric grinder with AC/DC capability that can work from outlets on generators and welders.
Grinder Accessories
Angle grinders use a variety of grinding and cutting wheels, depending on the material and the job at hand.
● Use a wire brush for stripping and cleaning. Clean old cement off a shovel or strip paint off the side of a building.
● A cutoff wheel can cut metal, ceramic and stucco. Use it to remove rusted bolts or chain link fencing.
● A grinding wheel is great for sharpening blades and tools like lawn mowers and axes.
● Use a diamond wheel to notch ceramic tile to fit around outlets or corners. It can also be used to easily remove old mortar from brickwork.
When using a grinder, keep safety as the top priority. For steel work on a bench grinder, keep a container of water nearby for cooling. If you are working with small objects like bolts and screws, use a pair of locking pliers to protect your hands from the tool and the sparks.
