印度采购需求：钻头套装、喷砂机、多功能刀片、SDS电钻、电动砂光机、硬质合金钻头

I'm looking to place an order for TCT, specifically requiring dimensions of 500 mm. It would be great if you could provide details regarding the available options for this size, including any specifications or variations that may be relevant. Could you also share the pricing, lead time for delivery, and any minimum order quantity requirements? If possible, please send through any product catalogs or samples that feature this size, as I'd like to ensure we get exactly what we need for our upcoming projects. Thanks!
