Grinding Wheel Selection — Quick Reference
Grinding wheel selection is a four-variable decision: abrasive type (material being ground), grit size (cut rate vs finish), grade (hard/soft bond), and structure (open/dense). Using the wrong wheel wastes consumables and creates safety risks. All bench grinder wheels must comply with AS 1788 grinding-wheel safety.
| Abrasive Type | Best For | Avoid |
|---|---|---|
| White Aluminium Oxide (WA) | Hardened steel, HSS tools, tool sharpening — cool cutting, friable | Heavy stock removal on mild steel (wears too fast) |
| Grey/Brown Aluminium Oxide (A) | General-purpose carbon steel + alloy steel grinding, stock removal | Hardened tool steel (less cool-cutting than WA) |
| Pink Aluminium Oxide (PA) | Tougher than white, between brown and white — versatile | — |
| Silicon Carbide (Green) | Carbide tools, cast iron, non-ferrous (brass, aluminium), masonry | Carbon + alloy steels (cuts but burns the surface) |
| Silicon Carbide (Black) | Cast iron, non-ferrous metals, stone | Heat-sensitive steels |
| CBN (Cubic Boron Nitride) | Hardened tool steel, HSS — long life, precision grinding | Soft steel (wasted on cheap material) |
| Diamond | Carbide, ceramics, glass, hardened materials | Steel (chemical reaction wears diamond rapidly) |
Grit guidance: 36-60 = roughing/stock removal | 80-120 = general purpose | 150-220 = finishing/sharpening. Grade: hard (H-K) for soft materials/long life | soft (J-M) for hard materials/cool cutting. Safety: ring-test before mounting, RPM-match to wheel rating, full-face shield + AS 1788 compliance. Brands: Norton, Pferd, Flexovit, Klingspor. Companion: bench grinder guide, all abrasives, safety glasses.
Shape, Sharpen and Finish Metal with Professional Grinding Wheels and Accessories
Grinding wheels are the consumable at the heart of surface grinding, bench grinding, cylindrical grinding and tool sharpening — used across engineering workshops, fabrication shops, toolrooms and maintenance departments.
Wheel grade, grit size, abrasive type and diameter all affect cut rate, surface finish and wheel life. Using the wrong wheel for the material wastes product and can create safety risks.
AIMS Industrial sells and extensive range of grinding wheels from Norton, Pferd, Flexovit and Klingspor — globally recognised abrasives manufacturers supplying precision grinding products to industry across Australia.
The Grinding Wheels & Accessories Range
Our extensive range covers bench grinding wheels, cup wheels, taper cup wheels and accessories in aluminium oxide and other abrasive grades from 100mm to 150mm diameter.
- Norton: Norton supplies grinding wheels and accessories including the White Aluminium Oxide series — a friable, cool-cutting abrasive particularly suited to tool and cutter grinding, HSS tool sharpening and precision surface grinding where heat-sensitive materials must be kept cool during the grind. Norton’s range spans bench grinding wheels, cup wheels and accessories for a broad range of workshop and production applications.
- Pferd: Pferd supplies grinding wheels and accessories including Flared Conical Cup Wheels for use on angle grinders and right-angle grinders. Pferd is a German precision abrasives brand known for consistent wheel quality and geometry accuracy — important in applications where the cup wheel shape directly influences the ground surface profile.
- Flexovit: Flexovit supplies grinding wheels covering general-purpose bench and surface grinding applications. Flexovit is a widely used abrasives brand across Australian manufacturing, fabrication and maintenance sectors, offering reliable performance across standard steel and cast iron grinding tasks.
- Klingspor: Klingspor supplies grinding wheels including taper cup wheels in 100–150mm diameters. Klingspor is a German abrasives manufacturer producing premium bonded abrasive products for professional grinding applications in steel, stone and concrete.
Choosing the Right Grinding Wheel
Matching the wheel to the application prevents premature wear, poor surface finish and safety issues from wheel loading or glazing.
- Abrasive Type: Aluminium oxide (including white aluminium oxide) is the standard abrasive for steel, HSS and tool grinding. Silicon carbide is used for non-ferrous metals, cast iron, stone and ceramics. Using the wrong abrasive type causes rapid glazing and reduced cut rate.
- Grit Size: Coarser grits (24–46) remove material faster but leave a rougher surface. Finer grits (60–120) produce smoother finishes and are used for sharpening and precision work. Match grit to whether you’re roughing, blending or finishing.
- Wheel Format: Flat bench wheels suit pedestal and bench grinders for tool sharpening and general grinding. Cup wheels (straight and flared conical) are used on angle grinders for surface and weld grinding. Taper cup wheels are used for concrete and masonry grinding on right-angle grinders.

People Also Ask — Grinding Wheels and Accessories
Q: What type of grinding wheel do I need for my work?
Bench grinder wheels (cylindrical, mounted to a shaft) for tool sharpening and general grinding. Angle grinder wheels (flat, mounted to a spindle) for cutting and surface grinding. Cup wheels for surface grinding flat work. Mounted points for die-grinder work in tight spaces. For specific abrasive choice, aluminium oxide handles general steel work; silicon carbide for harder materials and non-ferrous; diamond for tungsten carbide and ceramic.
Q: How do I read the markings on a grinding wheel?
Wheel markings follow ISO 525: abrasive type (A = aluminium oxide, C = silicon carbide), grit size (24 = coarse, 60 = medium, 120 = fine), grade (A-Z, hardness of the bond), structure (1-15, open or dense), bond type (V = vitrified, B = resinoid). Example: A36-M5-V means aluminium oxide, 36 grit, medium hardness, structure 5, vitrified bond. For workshop use, the wheel package summarises this in plain language.
Q: What's the right RPM for my grinding wheel?
Every wheel has a maximum RPM marked on the label or hub — never exceed this. Match the wheel's max RPM to your grinder's actual operating RPM. Standard 200mm bench grinder wheels run around 3,000 RPM; 125mm angle grinder wheels run 11,000-12,000 RPM; cutoff wheels for 4 inch angle grinders run 13,000-15,000. Mismatched wheel-to-tool RPM is a major safety hazard — shattered wheels cause serious injury.
Q: Why is my grinding wheel glazing or clogging?
Glazing (smooth shiny surface) means the abrasive is dull and not cutting — usually from running too hot or against too-hard material. Clogging (loaded with metal particles, especially on softer metals like aluminium) reduces cutting action. Both are fixed by dressing the wheel with a star-wheel dresser or diamond dresser. Periodic dressing maintains cutting efficiency and extends wheel life dramatically.
Q: Are flap discs different from grinding discs?
Flap discs use abrasive flaps bonded radially to a disc, presenting a continuous cutting edge as the disc wears — they grind aggressively but produce a smoother finish than rigid grinding discs. Standard grinding discs use a rigid bonded abrasive that cuts faster but leaves a rougher finish. Flap discs are workshop favourites for blending and finishing welds; grinding discs are better for heavy stock removal.
