Angle mills measure power output capacity in volts (V) and amperes (amps). how to buy an angle grinder.
5V to 24V. Voltage readings on corded angle mills just show whether they are ranked for 120V or 220V power outlets (what is angle grinder used for). Their power output capacity is determined in amperes and range from 5-amps to 15-amps, with many landing in the middle, at around 10-amps. how to use an angle grinder. Bigger discs will require a bigger output, so if you select a 7- or 9-inch mill, anticipate it to have a greater power output potential and a more powerful kick when it first starts cutting or grinding.
Some angle grinders have dust protection functions, like a dust seal or dust ejection system that keeps dust far from the vents and inner workings of the angle grinder's motor - what is angle grinder used for. If you'll often use an angle grinder in an environment with poor ventilation or for extended periods at a time, pick a model with built-in dust defense to extend the tool's life expectancy.
