How to choose angle grinders
• The size of the grinding wheels is essential for motor power. Disc diameters range from 100mm to 230mm. Size and power generally go hand in hand, as engine power increases the larger the disc is.
• Wattage is also an important measurement of the grinder’s power, as it indicates the rate of electricity that is required. Don’t pick a grinder that’s too powerful for your needs, or your power supply.
• The exact use of the sanding tool must be taken into account when deciding between a battery-powered grinder and a corded electric one. While the rechargeable battery offers a greater freedom of movement, the wired grinder has more power.
