diamond cup wheel

Ah, the diamond cup wheel—your go-to for grinding concrete, stone, and other tough materials. These bad boys feature a metal bond embedded with industrial diamonds to provide aggressive cutting and long-lasting durability. Typical sizes range from 4 to 7 inches in diameter, spinning at high RPMs to grind down surfaces efficiently. They’re a staple for pros and weekend warriors alike, available from around $50 to $150 AUD depending on quality and brand. Keep in mind, they wear down over time and aren’t suitable for softer materials like wood or metal. For a decent selection, check out Tradingpost or CarShowroom for tools and accessories.

Always consult the manufacturer's specs for compatibility with your grinder and intended use.
