Product advantages

Compared with steel, cast iron material is relatively easy to process. As long as the problem of iron filings is controlled well, it is easy to achieve high life

Iron machining can also use the shape of polishing inner groove, can be easier to remove iron filings! Easy to achieve high life on vertical machining centers

It can be made into double edge belt or single edge belt structure, improve the tool life and drilling quality
