► PFERD | Cutting Discs

Fast, Controlled Cutting Across Metal & More

Clean cutting starts with matching the disc to the material, machine & section being cut. PFERD cutting discs, also known as cut-off wheels, cover everything from thin sheet & profiles through to solid material, stainless fabrication, aluminium work, cast iron & selected stone applications.

The broader PFERD range includes cutting discs for angle grinders, straight grinders & petrol cutters, with different diameters, thicknesses & material-specific specifications available. That gives fabricators, maintenance crews, workshops & site teams a practical way to select around the actual cut rather than relying on one general-purpose disc for every job.

For the wider abrasive range, Grinding & Cut-Off Wheels covers complementary wheel formats, while Angle Grinders provides a direct route into compatible grinding equipment.

Start With What You're Cutting

The most useful first question isn't what diameter disc do I need?

It's what material needs to be cut?

PFERD produces cut-off wheels for different material groups, including applicable options for:

► Steel
► Stainless steel (INOX)
► Aluminium
► Other non-ferrous metals
► Cast iron
► Stone

Material-specific selection matters because the abrasive formulation is part of how the wheel is designed to perform. A disc that physically fits the grinder shouldn't automatically be treated as suitable for every workpiece.

Once the material is established, narrow the range by the type of cut, wheel dimensions & machine.

For broader fabrication cutting requirements, Metal Cutting & Grinding Tools provides another relevant pathway through the Industrial Shed range.

The Complete Guide Abrasive Cutting Grinding Discs provides additional workshop guidance around abrasive selection.

Thin Cutting Discs Suit Jobs Where the Cut Matters

Disc thickness has a direct relationship with how the wheel approaches the work.

PFERD's broader cut-off wheel range spans thin cutting discs through to heavier configurations, with widths ranging from approximately 0.8 mm to 4.8 mm across the wider range.

Thin cut-off wheels are particularly relevant where the job calls for a narrow cut through sheet, profiles or other suitable sections.

Depending on the individual disc, applications include:

► Cutting sheet metal
► Cutting profiles
► Cutting solid material
► Cutting out holes
► Fabrication cut-off work
► Workshop repair tasks
► Site cutting

The thinnest available disc isn't automatically the right choice. Material, section thickness, disc diameter, machine & individual wheel specification all belong in the decision.

STEEL, INOX, STEELOX, ALU & STONE Make Selection Clearer

PFERD uses material designations across its cut-off wheel families to help buyers identify the intended application.

STEEL variants are developed around applicable steel cutting.

INOX variants target stainless steel applications.

STEELOX products provide applicable options for both steel & stainless steel.

ALU variants address applicable aluminium requirements.

STONE identifies products intended for applicable stone cutting.

There are also specialised products within the wider range, so the designation should be treated as a useful selection guide rather than the only specification worth checking.

A practical sequence is:

► Identify the material
► Check the PFERD material designation
► Determine what type of section needs cutting
► Select the appropriate diameter
► Choose the required wheel thickness
► Confirm bore or mounting configuration
► Match the disc to the intended machine
► Verify the individual speed rating

Where cutting forms part of welding preparation or fabrication, Welding & Soldering Tools provides a logical route into the surrounding equipment.

Match Diameter to the Machine & Cutting Requirement

PFERD's broader cutting-wheel range covers a substantial size spread, with diameters from approximately 30 mm through to 400 mm across portable-machine applications.

That range exists because a small straight-grinder wheel has a very different job from a large cut-off wheel used with heavier cutting equipment.

Before choosing by diameter alone, check:

► Machine type
► Disc diameter permitted by the machine
► Bore size or mounting system
► Wheel thickness
► Material specification
► Maximum RPM
► Required cutting depth

A larger diameter doesn't automatically make a wheel better. The correct diameter is the one designed to work with the machine plus the cutting requirement.

Choose the PFERD Performance Line Around the Workload

PFERD separates cut-off wheels across different performance levels, including PSF, SG & SGP families.

Rather than treating those names as interchangeable, think about how frequently the wheel is being used plus what the application demands.

PSF provides PFERD's introductory performance line across applicable cutting applications.

SG covers a broad performance range intended for productive professional use across numerous materials & cutting requirements.

SGP sits within PFERD's high-performance offering for applicable demanding applications.

The correct choice isn't necessarily the highest performance line every time. A workshop making occasional cuts has a different consumable requirement from a fabrication operation cutting material repeatedly throughout the day.

Consider:

► Material
► Cutting frequency
► Required cutting performance
► Expected wheel life
► Machine power
► Disc dimensions
► Cost per completed job rather than unit price alone

Straight Grinders Need the Right Small Cut-Off Wheel Setup

Not every cutting disc belongs on an angle grinder.

PFERD also produces small cut-off wheels for straight grinders, giving workshops a compact cutting option for applicable detailed work & areas where access is limited.

These smaller wheels can use separate compatible arbors, so the disc plus mounting hardware need to be considered together.

Before ordering a small cut-off wheel, confirm:

► External diameter
► Wheel width
► Bore diameter
► Compatible arbor
► Straight-grinder suitability
► Disc speed rating
► Arbor speed rating

Where a wheel plus arbor have different maximum rotational speeds, the complete setup must remain within the applicable operating limit.

This is a good example of why cutting-disc selection needs to go beyond diameter plus grit.

Cutting Disc or Grinding Disc?

They may sit next to each other in the workshop, but they perform different jobs.

A cutting disc is designed around cutting through material.

A grinding wheel is intended for applicable grinding tasks such as material removal, edge work or surface correction.

That distinction matters because a cutting disc shouldn't be selected as though it were simply a thinner grinding wheel.

If the job is to separate a profile, sheet or solid section, start with an applicable cut-off wheel. If the next stage involves cleaning the cut, removing material or refining an edge, move to an abrasive designed for that operation.

This creates a cleaner workshop process:

► Cut with the appropriate cutting disc
► Inspect the cut area
► Change abrasive format when grinding is required
► Refine or finish with the appropriate later-stage abrasive

For workshops moving from cutting into surface refinement, Polishing & Buffing Accessories provides a pathway into later finishing stages.

Let the Material, Section & Machine Make the Decision

With a large cutting-disc range, selection becomes easier when the variables are considered in the right order.

Start here:

► Material – steel, INOX, aluminium, cast iron, stone or another applicable material
► Section – sheet, profile, solid material or another cutting requirement
► Machine – angle grinder, straight grinder or applicable cutting equipment
► Diameter – match the machine plus required cutting depth
► Thickness – select around the cutting application
► Mounting – confirm bore or arbor requirements
► Performance line – match the wheel to workload
► Speed – verify the exact disc's operating limit

This gives buyers a repeatable process rather than expecting a product title alone to answer every compatibility question.

Cutting Starts With the Complete Setup

A correctly selected disc still needs to be used with compatible equipment plus appropriate workplace controls.

Before cutting:

► Confirm the disc is intended for the workpiece material
► Check diameter plus bore compatibility
► Inspect the wheel before fitting
► Confirm the machine is suitable for the disc
► Verify the individual maximum RPM
► Check applicable arbor limits on small-wheel systems
► Secure the workpiece appropriately
► Use relevant guards plus workplace controls
► Use PPE appropriate to the task plus site requirements
