The size of the disc on your angler will vary from small to large. The most common sizes are 4.5-inch, 5-inch, 6-inch, 7-inch, and 9-inch disc. If you’re looking for small jobs, welding, and finishing up your work, you should go for a 6-inch or less disc. If you want to cut your metals, a larger disc size would be better.
You should check the speed of the disc before your purchase because the higher the number, the more effective it will be. The rotations can vary between 5,000 to 10,000 revolutions per minute. The no-load speed of the device matters as well. This one ranges between 700 to 1,200 RPM. Some even extend up to 12,000 RPM.
Higher wattage means more power to cut through thicker materials, so you should pay attention to the number as the density of your material increases. If you plan on using your grinder for long periods of time, a higher wattage is recommended as well.
Look for slow-start, anti-kickback, and deadman paddle switches. All of this help keep you safe and reduce the chances of injury.
Slow start means, the motor starts slow and gradually speeds up to its highest speed. Anti-kickback means your grinder will cut out if the wheel is bound up. Finally, the paddle switch makes sure the motor shuts down if your hand releases the switch.
The adjustability of the side handle will make it easier for you to use your grinder from whatever position makes you feel most comfortable.
The more positions available, the freer you will be to work from whatever angle and thereby the greater your efficiency.
