Be sure to utilize the right disc for the task and note the optimum supported speed marked on the disc. how to use an angle grinder. For example, a disc rated at 7,500 RPM that is run at a faster speed can break under the force, sending out fragments of the mill wheel flying - what is an angle grinder. Angle grinders determine power output potential in volts (V) and amperes (amps). how to cut bricks with angle grinder.
5V to 24V. Voltage readings on corded angle mills just indicate whether they are rated for 120V or 220V power outlets (how to use an angle grinder to smooth concrete). Their power output potential is measured in amperes and range from 5-amps to 15-amps, with a lot of landing in the middle, at around 10-amps. how to use an angle grinder. Bigger discs will require a bigger output, so if you choose a 7- or 9-inch grinder, expect it to have a higher power output capacity and a more powerful kick when it initially starts cutting or grinding.
Some angle grinders have dust protection functions, like a dust seal or dust ejection system that keeps dust away from the vents and inner operations of the angle mill's motor - how to cut a straight line with an angle grinder. If you'll regularly use an angle grinder in an environment with bad ventilation or for long periods at a time, select a model with integrated dust protection to extend the tool's lifespan.
Some angle mills use a portable guard and others a set guard. The portable alternative is more popular as it enables left-handed or right-handed use and can be adapted to better safeguard you from flying debris (how to use an angle grinder). But, if left untightened, a moveable guard can fall off the unit (how to use a angle grinder). Repaired guards are more robust and there's no risk of it coming off the mill.
