Buying Guide
90 Degree Angle Grinder Buying Guide
A 90-degree angle grinder is a versatile tool perfect for tight spaces and detailed work. This buying guide will help you choose the right one for your needs.
Power and Speed
Consider the motors amperage. Higher amperage, like 7-10 amps, generally means more power for tough tasks. Look at the RPM (revolutions per minute) as well. A variable speed grinder, offering speeds from 2,500 to 10,000 RPM, provides more control for different materials and applications like removing rust or polishing.
Size and Ergonomics
The grinders size impacts maneuverability. Compact models are easier to handle in confined areas. Pay attention to the grip. A comfortable, vibration-dampening handle reduces fatigue during extended use. Consider the weight; a lighter grinder is easier to control.
Safety Features
Prioritize safety. Look for features like a paddle switch for easy on/off and a wheel guard that covers a large portion of the grinding wheel. Consider models with a lock-on switch to reduce hand fatigue during prolonged use.
