Hi everyone! I’m Mrbrianzhao, and today I’d like to introduce two types of small grinding wheels for internal bore grinding—the **Straight Wheel (Type P)** and the **Recessed One-Side Wheel (Type PDA)**.*
These wheels use ceramic bonds and are perfect for grinding inner holes or walls of workpieces. Whether you’re working on regular metals, super-hard alloy steel, or brittle non-metals like ceramics and glass, they deliver fast, efficient, and high-precision results—great for both rough and fine grinding.
You can choose from different abrasive materials like **White Alumina (WA), Pink Alumina (PA), Brown Alumina (A)**, or **Green Silicon Carbide (GC) and Black Silicon Carbide (C)**—each suited for specific materials. Grit sizes range from ** #36 to #100** (finer with higher numbers), and hardness grades go from **K to N** (softer to harder). Just pick the right combo for your job!
