Cut-Off Wheel Selection — Quick Reference
AIMS stocks THIN CUT-OFF WHEELS for ANGLE GRINDERS from PFERD + KLINGSPOR — precision abrasive discs for FAST CLEAN CUTTING of steel + stainless + aluminium. Cut-off wheels = primary consumable for grinder-based cutting.
| Cut-Off Wheel | Best For | Thickness |
|---|---|---|
| Standard Cut-Off (1.6mm-3mm) | General steel + medium-section cutting | 1.6-3mm |
| Ultra-Thin (1mm-1.6mm) | Stainless + thin sheet — minimum heat input | 1-1.6mm |
| Heavy-Duty (3mm+) | Heavy section + rebar + structural | 3mm+ |
| Stainless-Specific (Inox) | Stainless cutting — no iron contamination | 1-2mm |
| Aluminium-Specific | Aluminium — different abrasive bond | 2-3mm |
| Standard Diameter (115mm / 125mm / 230mm) | Match to angle grinder | — |
| RPM Rating (MAX) | NEVER exceed marked max RPM | — |
Critical safety: NEVER use cut-off wheel for GRINDING (grinding wheels are thicker + designed for side loading). Cut-off wheels SHATTER under side load. Always use SAFETY GUARD. PPE — face shield + leather gloves + welding jacket + dust mask. Match wheel speed rating ≥ grinder RPM. For stainless use Inox-specific wheel (no iron particles = no rust contamination). Brands: Pferd, Klingspor, Norton. Companion: cutting wheels, abrasives, grinding wheels.
Cut-Off Wheels
AIMS Industrial stocks thin cut-off wheels for angle grinders from Pferd and Klingspor — precision abrasive discs for fast, clean cutting of steel, stainless steel and aluminium. Cut-off wheels are the primary consumable for angle grinder cutting work, and selecting the right wheel for the material and grinder size directly determines cutting speed, cut quality and wheel life.
Sizes and Thickness
Cut-off wheels are stocked across the standard angle grinder sizes used in Australian workshops and on site. 115mm (4.5-inch) wheels suit compact angle grinders for portable hand cutting work. 125mm wheels cover general workshop cutting on mid-range grinders. 180mm wheels are used on larger bench and portable grinders for heavier structural and plate cutting. 230mm wheels suit heavy-duty industrial grinders where cutting depth and wheel life per disc are the priority. Thickness ranges from 1.0mm ultra-thin for fast cutting with minimal material loss to 1.6mm for greater durability on longer cuts in tough materials — thinner wheels cut faster and generate less heat but are more fragile; thicker wheels are more robust but slower.
Metal vs Stainless-Specific Wheels
Standard aluminium oxide cut-off wheels for mild steel and general metal are the everyday workhorse for structural steel cutting, pipe cutting and fabrication work. Stainless-specific cut-off wheels use a different abrasive formulation — typically zirconia alumina — designed to handle the work-hardening characteristic of stainless steel, which causes standard wheels to glaze and bind rather than cut cleanly. Using a stainless-specific wheel on stainless steel produces a cleaner cut edge, extends wheel life and reduces the heat input that causes surface discolouration and carbide precipitation in the heat-affected zone.
Safety and Correct Use
Always inspect cut-off wheels for cracks and damage before mounting — a cracked wheel that disintegrates at speed is a serious hazard. Never exceed the maximum RPM rating marked on the wheel; the maximum RPM is determined by wheel size and bond strength, and using a small-diameter wheel on a large grinder running at its rated free speed can exceed the wheel’s safe operating speed. Ensure the grinder guard is correctly positioned before cutting — the guard deflects disc fragments away from the operator in the event of a disc failure. Wear eye protection and a face shield. Do not use cut-off wheels for grinding — they are designed for edge cutting only and side loading will cause the disc to shatter. Never force a wheel into a cut; let the abrasive do the work and maintain light, consistent feed pressure.
