How To Choose The Best Angle Grinder Blade For Cutting Metal?

Disc size

The disc size, or the diameter of a cutting disc, plays a critical role in your cutting time. That says, bigger discs can help you get your metal cutting jobs done faster than smaller ones. Don’t forget to check if the disc size is compatible with your tool or not.

Apart from the disc size, you should also check the disc’s thickness. Ultra-thin discs are often recommended for smooth and accurate cuts.

Disc quality

Aluminum oxide is the best material for an angle grinder wheel to cut metal. Discs made of this material are sturdy and robust for high-demanding jobs with no wear or tear.

Disc quantity

The number of discs depends on how often you will use your angle grinder.

For example, if you are a homeowner or DIY hobbyist who occasionally uses this powerful tool for simple, light-duty tasks, you only need to prepare one disc.

But if you want your device to perform various applications on many different materials, you should buy more than one disc.

RPM

The RPM (revolutions per minute or rotations per minute) equals the maximum number of turns that an angle grinder disc can handle per minute. The higher the RPM, the faster the disc can perform.

You should choose fast wheels for cutting or grinding through metal easily and quickly. The RPM of a wheel should not be lower than 3,900 RPM.

Material compatibility

You should ensure that the disc is compatible with the working material and the tool for your performance and safety. For example, a grinding disc that can work on fiberglass only can’t be used for other materials.

A metal cut-off disc is versatile since it can be used for various materials.

Easy to assemble/disassemble

The ease of use is an essential factor for both beginners and professionals. Make sure your chosen disc is easy to assemble or disassemble on your grinder. Otherwise, you will end up breaking the disc or hurting your hands.

How To Cut Metal With An Angle Grinder?

Choose your required tools

Before beginning your metal cutting job, ensure that you have all the following essential tools for the work:

  • The best angle grinder
  • An appropriate power supply
  • A long electric cord (if your grinder is a corded electric one)
  • Earmuffs
  • A proper metal cutting/grinding disc
  • A C-clamp to clamp your metal
  • A shop drawing or a sample/a template of the work

Prepare safety gears

For your safety, you should wear some required safety gears when working with this powerful and fast tool:

  • Eyeglasses – to prevent hot sparks from burning your eyes
  • Safety work boots – to protect your feet
  • Long and tight sleeves/ pants or bib overall – to avoid the clothes from entangling the power cord or the tool
  • Protective gloves – to keep your fingers and hands safe from sharp metal particles
  • Secure floor – to prevent unwanted falls. Your working area should be dry and free of flammable objects, litter, obstacles, and water spillages.

Wear Safety Equipment

Install the disc onto your grinder

To do this, open the spindle, put the metal disc, then tighten the spindle nut to keep the disc in place.

Remember to unplug the tool (if it is a corded one) or remove the battery (if it is battery-powered), and wear all your protective gear when assembling the disc.

Mark your cut

Clamp the metal securely on the worktop, then use a scratch awl to outline the cutting lines that you want to perform on the metal.

  • For straight cuts: mark the two ends of the cutting line, then make a straight line to connect these two ends.
  • For pattern/zigzag cuts: draw all the bends of the design, sketch the straight lines with an awl, then highlight the entire cutting line.

mark the metal before cutting

Turn on the tool and start cutting carefully

Switch on the angle grinder to make the disc rotating. Then, hold the tool securely with two hands and start your first cut lightly by following the outlines and letting the disc do its job.

Smoothen your cut

After finishing the cutting lines, the rough-cut edges are still sharp and dangerous to touch.

You should smoothen these edges with a 40-grit flapper disc. Install this disc on your tool, then run it along these rough edges to make it safe to touch.

Extra tips

To use your tool safely and efficiently, follow some extra tips:

  • Let your grinder rest for a few hours before using it again.
  • An angle grinder can perform cuts on many types of metals like sheet metal, hard steel, etc. To cut hard metal, you need to use a diamond cutting disc to cut quickly.
  • Angle grinders are versatile but can be dangerous even for professionals. Thus, you should be careful when using it.
  • Follow the safety instructions from the tool’s manufacturer before starting your project. This extra step will guarantee to maintain your performance and protect you from possible accidents and damages.
