South Bay Supply

What South Bay Supply does

South Bay Supply LLC is a privately held wholesale distributor and light custom manufacturer of superabrasive and conventional abrasive grinding products, founded in 2014 and headquartered in St. Clair Shores, Michigan. The company sells Diamond and CBN (Cubic Boron Nitride) grinding wheels across four bond technologies — Resin, Metal, Vitrified, and Electroplated — alongside conventional abrasive wheels, dressing sticks, handcrafted diamond dressers, and tapping compounds, serving industrial manufacturers performing OD, ID, surface, Blanchard, honing, and tool-and-cutter grinding operations.

The technical core of the offering is application engineering: selecting crystal type, grit, and bond configuration to optimize grinding performance on materials ranging from carbide, glass, and ceramics to tough steels and superalloys. The firm has developed proprietary Metal Bond systems specifically for refractory brick, alumina, and fused silica grinding, and markets multiple proprietary Resin Bond and crystal combinations under its own label, in addition to reselling specifications from leading US abrasive manufacturers.

The business model is direct, quote-based sales with short lead times on both standard in-stock items and custom engineered wheels. The company reaches customers through its website, IMTS trade show presence (booth 237138), and inbound quote requests, with application engineering support bundled into the sales process. Operations are single-site, founder-led by President Chuck Stormes, and serve a horizontal industrial manufacturing customer base in the US Midwest.
