澳大利亚采购需求：径向刷毛盘

I'm looking for a supplier for 150mm diameter radial bristle discs to create a wheel that's approximately 50mm thick. This product will be essential for fine sanding the raw edges of timber slabs, which are the primary materials in my business. Additionally, I need this to be compatible with a cordless angle grinder, so an extension M14 thread fitting is required. Please provide detailed pricing and an itemized list of these products. I appreciate your prompt response as I'm eager to move forward with this purchase.
