205mm x 25mm White Aluminium Oxide Grinding Wheels - Multi Bore

White Aluminium Oxide Precision Grinding Wheel

205mm x 19mm - Stepped Multi Bore Included to fit most machines.

Manufactured from high purity white aluminum oxide, perfect for high-speed steel and other heat sensitive materials.

Unlike standard grey aluminium oxide, the white variant is more friable, meaning it breaks down under pressure to continually expose fresh, sharp cutting edges. This ensures cooler cutting action, reduces the risk of overheating, and leaves a finer surface finish.

Key Features: 

White Aluminum Oxide (WA): A friable, high-purity abrasive that self sharpens as it grinds, delivering consistently smooth and cool cutting.

Excellent for Sharpening: Especially suited to sharpening lathe tools, woodworking chisels, plane irons, and other edged tools.

Reduced Heat Buildup: Cooler operation helps preserve tool temper and edge hardness during grinding.

Smooth Finish: Ideal for both rough shaping and final edge refinement.

Medium Grit (46): Cuts aggressively and removes material fast, ideal for for heavy duty grinding and sharpening jobs.

Fine Grit (typically 60, 80, 120): Offers a balance between material removal and surface finish, making it ideal for everyday use in workshops.

Applications:

Sharpening hardened and high-speed steels (HSS)

Sharpening lathe tools, drill bits, knives, and other cutting edges.

Where maintaining edge integrity and avoiding burn marks is critical.

Max RPM: 3600

Max M/S: 40

Multi Bore

Includes a full multi bore bush set (12.7, 15.8, 19.05, 22.0, 25.4, 31.75)mm

Dressing Sticks 

As you grind the wheel gets loaded or loses its sharpness - using a dressing stick exposes fresh sharp grain, restoring the cutting edge.
