10 Best Angle Grinders Reviews & Buying Guide

Angle grinders, commonly known as disc or side grinders, are vital tools in workshops and construction sites. They provide power and versatility for various tasks like cutting, grinding, and polishing. Choosing the appropriate angle grinder is crucial for achieving optimal results, whether you’re a professional or a DIYer.

Key Considerations:

  • Power: Angle grinders vary in power from approximately 500 to over 2500 watts, with higher-wattage models providing enhanced cutting and grinding abilities. Opt for a high-power angle grinder, ranging from 1500 to 2500 watts, for demanding applications like cutting metal or concrete.
  • Disc Size: Angle grinders come in various disc sizes, including 4.5-inch, 5-inch, 7-inch, and 9-inch discs. The disc size determines the depth and area of material that the grinder can cut or grind in a single pass. Smaller discs are suitable for precise work and lighter tasks, while larger discs excel at cutting through thicker materials.
  • Speed: Angle grinders typically feature variable speed settings, enabling you to adjust the RPM to match the material and application. Look for a grinder with a broad speed range, from around 5000 RPM for precision work to over 10,000 RPM for rapid material removal.

What Can We Do With This Angle Grinder?

The angle grinder is a versatile tool used widely for grinding metal, routing out the mortar, cutting tile/rebar/stucco, polishing, sharpening and sanding. Although, it comes in different sizes but we use 4 – 4 ½ inch grinder to complete most of the tasks. It is a must-to have tool for any service garage, auto repair shop, workshop or home hobbyist.

There are some risks involved while using this tool but most of the modern models will ensure safety along with delivering performance. Now let’s know, for what purpose we use this grinder mostly.

  • Cleaning – A wire cup is attached to this power tool for cleaning caked on cement and rust from various tools. But be sure that to spin the brush away from the edges of tool or else you may experience kick back.
  • Cutting Rebar – Simply, attach a metal cutoff wheel to the angle grinder for cutting tough rebar in concrete, but make sure the tool is tightened securely. Drop this cutoff wheel after cutting through metal to reduce the weight of the tool. Angle grinders is much quicker and easier to use than hacksaws. Also, you can use a high-quality metal cutting saw to do this cutting.
  • Sharpening Blades – An angle grinder has its ease of use and power while sharpening other tools. Simply secure the blade in a vise and position the tool. Try to adjust the blade guard to prevent sparks and align the angle grinding wheel on the blade and start grinder. Apply slight pressure while moving the wheel across the blade to sharpen it.
  • Scoring Tile – One can easily score through the middle of a tile by using a diamond blade. For example, if you want to cut a hole in an outlet then you have to mark the outline of the hole size. Now secure the tile with a clamp to the workbench. Score about 1/8-inch deep on the front of tile with the grinder. It is much easier than using a tile cutter.
  • Grinding Out Mortar – The tuck pointing wheel of the angle grinder will allow you to grind out the old, loose mortar. Simply make 2 – 3 ½ inch deep drills to clear out the joint completely and keep 1/8-inch away from brick.

Factors to Consider When Choosing a Power Conditioner

When choosing a power conditioner for your electrical devices, it’s important to consider several key factors to ensure they perform well and stay protected. Knowing these factors will help you make a smart choice that suits your needs.

1. Voltage Regulation

The main purpose of a power conditioner is to control voltage changes, guaranteeing a steady and reliable power flow to your equipment. When assessing power conditioners, it’s important to check their voltage regulation capabilities. Opt for models with advanced voltage regulation technology that can uphold a consistent output voltage within a defined range, even when the incoming power supply experiences fluctuations or disturbances.

2. Surge Protection

To protect your electronic devices from electrical surges and spikes, invest in a strong power conditioner. Look for models with advanced surge protection that can detect and stop voltage spikes before they harm your devices. Choose a power conditioner with a high joule rating to ensure solid defense for your equipment.

3. Noise Filtering

Electrical noise, or interference, can mess up how your equipment works by adding unwanted signals and disruptions to the power it gets. To fix this, focus on getting power conditioners that can filter out this interference well. Choose ones that use different filtering technologies, like ferrite cores, inductors, and capacitors. These filters help keep your power supply clean and steady, so your devices can work properly without any annoying disruptions.

4. Power Capacity

It’s important to match its capacity with the total power your devices need. Make sure the conditioner can handle all your devices without getting overloaded. Overloading might cause problems or damage. It’s smart to pick a conditioner with a bit more capacity than you currently need, so you can add more devices later without any issues.

5. Number of Outlets

It’s crucial to verify the types and number of outlets accessible to ensure they’re compatible with your devices. Confirm there’s an adequate number of outlets for all your gadgets, including any specialized plugs or connectors. Additionally, consider the spacing between outlets to ensure that larger power adapters can fit without obstructing adjacent sockets.
