匈牙利采购需求：17 4ph、316ti、a312 tp304、aisi 304l、异型管、异形管

I'm in need of a hex tube for a demolition hammer chuck, specifically looking for options with internal hex sizes of 28.5mm, 29mm, or 32mm. The length required is 100mm. Could you please provide details on availability and pricing for these sizes? If you have any recommendations for similar products that might work, I'd appreciate that as well. Thanks!
