Best Angle Grinder (October 2019) – Top 10 Picks & Reviews
KNOW WHAT TO LOOK FOR the best Angle Grinder
To choose the right one means understanding the important things you need to consider upon buying this powerful tool. Below are some of the common features and factors you need to look for in picking the best angle grinder.
1. Torque and RPM
This is the main factor you need to consider as this rotational force is responsible for effective cutting, grinding, sanding, and polishing actions of the power tool. Rotational speed or RPM is a tricky thing to look at, particularly the free load rpm.
Some tools have high free load rpm rating but the torque magnitude is low while others are the opposite – low to medium rpm with high torque level. It is best to choose a grinder with higher rotational force rather than high rpm rating.
2. Types of Wheels
For different functions, you will be using various kinds of wheels. Make sure to know what is the sole purpose for buying an angle grinder and what wheel type it can accommodate.
3. Size of Disc
This factor depends on the area you will be working on. For larger areas, use a larger disc size approximately 7 inches and larger. For home or smaller projects, a smaller disc size of about 4.5 to 5 inches is suitable. The smaller disc size allows you to move through tight spaces and corners.
The wattage specs depend on the type of project you will be working on. In general, the wattage range for most angle grinders is between 500 to 2500 watts with a voltage rating ranging from 110 to 230 volts.
In addition, to directly determine if the angle grinder is strong, look for its amp specification. Typically, the amp ratings of this power tool range from 4 to 15 amps.
5. Grip Handle
This is a hand-held power tool which creates a lot of tension and vibration that is transferred to your hands. If working for long hours, expect hand fatigue afterwards. In order to minimize this weariness, get a feel of the grip handle of the grinder.
A grip handle insulated with soft rubber is most ideal. Likewise, a textured one is better for it promotes better grip and a lesser chance of slippage.
6. Adjustable Guard and Safety Lock
These two features enhance safety while using this power tool. The blade guard must be adjustable to allow you to work on various angles while still having the protection.
Meanwhile, the safety lock switch is there to prevent any accidental start-ups which might incur harm for any user.
