Choosing the right angle grinder cutting discs can make a big difference to cutting speed, finish quality and overall performance. Metal, stainless steel, porcelain, ceramic and stone all behave differently when cut, which means one cutting disc isn't necessarily the right choice for every job.
At HanzTools, our cutting range includes metal cutting discs in multiple sizes as well as specialised diamond cutting blades for hard materials. Here’s a straightforward guide to choosing the right option for your next job.
Metal Cutting Discs for Angle Grinders
For fabrication, workshop and general metalworking jobs, metal cutting discs for angle grinders are designed to produce fast, controlled cuts through common metal materials.
HanzTools metal cutting discs use reinforced construction and aluminium oxide abrasive to provide consistent cutting performance.
Our range includes multiple popular sizes:
- 4.5 inch / 115mm cutting discs
- 5 inch / 125mm cutting discs
- 7 inch / 180mm cutting discs
- 9 inch / 230mm cutting discs
This gives users the flexibility to choose a disc based on their grinder, material and the scale of the job.
For smaller handheld grinders, 4.5 inch cutting discs and 5 inch cutting discs are practical options for everyday workshop and fabrication work. Larger 7 inch cutting discs and 9 inch cutting discs are suited to compatible larger grinders when greater cutting capacity is required.
Cutting Metal and Stainless Steel
When you're working with steel or stainless steel, selecting a disc intended for the material is important.
Our cutting discs for metal and stainless steel are available in thin cutting profiles, helping produce efficient cuts while limiting unnecessary material removal.
Selected HanzTools cutting wheels are rated for maximum operating speeds of up to 80m/s, with the permitted RPM depending on the diameter of the individual disc.
Always check the specifications printed on the disc and make sure they are compatible with your angle grinder before use.
What About Tile, Porcelain and Stone?
A conventional abrasive metal cutting wheel isn't the right choice for every material.
For materials such as porcelain, ceramic, granite, marble, concrete, brick and stone, a suitable diamond cutting blade for an angle grinder may be required instead.
Diamond blades use a diamond-containing cutting edge rather than the abrasive construction typically found in metal cut-off wheels.
HanzTools currently offers three 4.5-inch diamond blade designs, each intended for different cutting requirements.
DID-345 Segmented Diamond Blade
The HanzTools DID-345 is a 4.5-inch segmented diamond blade.
Its segmented rim is designed for fast cutting, making it suitable for compatible applications involving materials such as concrete, brick and stone.
The blade features a 15mm diamond band and can be used for wet or dry cutting where appropriate.
If cutting speed is more important to your job than achieving the smoothest possible edge, a segmented blade is often the more suitable style.
DID-545 Porcelain Cutting Blade
Porcelain can be particularly demanding to cut because of its density and hard surface.
The DID-545 is our dedicated 4.5-inch porcelain cutting option, featuring a 12mm diamond band.
For users specifically searching for diamond blades for porcelain and ceramic, choosing a blade intended for these hard materials is preferable to simply using a general-purpose cutting wheel.
This makes the DID-545 worth considering for tiling, renovation and other jobs involving porcelain.
DID-145 Continuous Rim Diamond Blade
Where the quality of the finished edge is a priority, the DID-145 provides another option.
This 4.5-inch diamond blade uses a continuous-style rim designed to provide a smoother finish and is suitable for materials including tile, ceramic and marble.
It features a 10mm diamond band and supports wet or dry cutting.
For jobs where reducing rough edges is more important than maximum cutting speed, a continuous-rim design can be a better fit.
Segmented vs Continuous Rim Diamond Blades
The visible difference between diamond blades isn't just cosmetic.
A segmented diamond blade has gaps around its cutting edge. This design is commonly used when faster material removal and effective debris clearance are important.
A continuous rim diamond blade has a more continuous cutting edge and is generally chosen when a smoother finished cut is the priority.
That means the right choice depends heavily on what you're cutting.
For concrete, brick and general stone work, a segmented blade may be appropriate. For tile, ceramic or marble where the finished edge matters more, a continuous-rim blade may be preferable.
Porcelain is another case where using a blade specifically designed for the material can help achieve better results.
Wet and Dry Diamond Cutting Blades
Another consideration is whether your application requires wet or dry cutting.
Several HanzTools options are designed as wet and dry diamond cutting blades, giving users more flexibility depending on the material, equipment and working environment.
Wet cutting can help with cooling and dust management in suitable applications, while dry cutting can be more convenient for certain jobs where water isn't practical.
Always follow the blade manufacturer's instructions and the requirements of the power tool being used.
How Do You Choose the Right Angle Grinder Cutting Disc?
Start with the material.
If you're cutting metal or stainless steel, look for an abrasive cutting disc specifically rated for that material.
If you're cutting porcelain, ceramic, marble, granite, concrete, brick or stone, look at the appropriate diamond blade instead.
Then check the disc diameter and bore size against your angle grinder. A 4.5-inch grinder needs a compatible blade; you should never choose a larger disc simply because you need a deeper cut.
Finally, consider the type of result you're trying to achieve. Fast material removal, smooth edges and general-purpose cutting can call for different blade designs.
HanzTools Cutting Disc Range
HanzTools offers angle grinder cutting discs for a range of metalworking, fabrication, tiling, renovation and stone-cutting applications.
Our current range includes multiple sizes of abrasive metal cutting wheels alongside specialised 4.5-inch diamond blades, allowing you to choose according to the material and job rather than trying to use one type of disc for everything.
Whether you're looking for metal cutting discs for angle grinders, a porcelain cutting blade or a wet and dry diamond blade for tile and stone, always check the individual product specifications before choosing your disc.
