Criteria When Buying the Best 4 1/2 Angle Grinder

Criteria When Buying the Best 4 1 2 Angle Grinder

 

We all want to get the best thing when we need to buy something. There are some issues that we should consider when buying the best 4-1/2 inch angle grinder. Let’s know them.

 

Motor

The motor is the main part of a grinder which is the basis for the work performed. The power of a motor is measured by amperage. Typically, an angle grinder comes with an amperage of 6Amp to 15Amp. The higher the amperage, the more aggressive a grinder.

 

Corded or Cordless

In terms of portability, cordless grinders are preferable to corded angle grinders. They are perfect light projects.

 

But a cordless grinder is heavier than a corded grinder as the cordless grinder is powered by an included battery and for its additional weight, this kind of grinder can’t manage high output. If you need higher power output, you are recommended to get a corded angle grinder.

 

RPM

Revolutions Per Minute (RPM) is an important fact while choosing the best angle grinder. Higher RPMs generate greater speed. It is imperative to check on the maximum RPM of the wheel before inserting it in a grinder.

 

The wheel might be damaged if you use a wheel with lower RPM than the grinder. As a rule of thumb, small angle grinders come with higher RPMs of up 11,000 to 12,000 RPM while larger models provide 6,000 to 9,000 RPM. Variable speed options and soft-start features also allow for use with lower RPMs, e.g. < 3,000 RPM.

 

Variable or Fixed Speed

Fixed speed angle grinders don’t allow to change the speed limit. But variable speed angle grinders allow controlling the RPMs for ease and comfortable work. This kind of grinder is preferable to polish sensitive metals or surfaces.

 

Disc Type

There are different kinds of discs including cutting discs, flap discs, grinding discs, and wire discs. Cutting discs are the thinnest of all discs and they are good for cutting metals. Grinding discs are usually 5mm or thicker and are used for clearing or smoothening rough surfaces.

 

Flap discs are coated with sandpaper and are used for creating smoother surfaces. Wire discs are used for polishing metals or removing paints. You need to choose the right type of disc depending on the work you’re going to do.

 

Disc Size

When you buy a 4-1/2 inch angle grinder for DIY jobs, you should be considering which maximum size you might need in the next coming years. Because the disc size is linked to the grinder’s specification.

 

Spindle / Arbor Size

A spindle is the shaft of an angle grinder on which the disc or wheel is mounted indicating which kind of wheels or discs can be used in the grinder. The standard spindle size for the small 4-1/2 inch angle grinder is 3/8″-24 ( which means:3/8 inches of diameter with 24 threads per inch).

 

Ease of Changing the Disc

The way to change the disc is very important. You should select the grinder which has a Quick-Change-Wheel-Release feature that allows you to change the wheel easily without using a tool.

 

Safety

The best angle grinder offers some safety features for the users including anti-kickback, vibration control, overload capacity, auto brush-off, and so on.

 

Type of Switch

There are two types of switch-Paddle switches and Slide up switches. Slide-up switches are easier to use.

 

Price and Warranties

When you chose an angle grinder to buy, you should consider the price tag and warranties given by the manufacturer.

 

 

 

Safety Considerations When Using an Angle Grinder

Safety Considerations When Using an Angle Grinder

 

Using an angle grinder can be very dangerous if the tool is operated unsafely and improperly. The sparks can harm the users, an operator could lose grip, or a disc can break. So, we should follow some safety considerations when using an angle grinder. Let’s know them.

 

  • Always wear protective gear before working with an angle grinder, heavy-duty gloves, protective glasses, earplugs, masks, and working overalls.
  • If you are a newcomer, try to follow the manufacturer’s instructions thoroughly.
  • Make sure that the tool is unplugged when inserting or changing the wheels.
  • Use the safety guard.
  • Secure the workpiece with the workbench.
  • Make sure the grinder isn’t jammed to keep away from the kickback.
  • Hold the handle maintaining a firm grip with both hands.
  • Let the new blade running for one minute to make sure the blade isn’t defective.
  • Constant pressure on the same area can heat the blade and damage it. Use water to cool down the blade between strokes.
  • Keep the bystanders away from the workplace.
  • Keep sparks away from flammable substances.
  • Store angle grinders out of children’s reach.
