Product advantages
Compared with steel and cast iron, aluminum alloy materials are relatively easy to work with. As long as the problem of iron filings is well controlled, it is easy to achieve a high life
Aluminum bits are typically polished with an internal groove shape, which allows easier removal of iron chips, longer tool life, and better hole accuracy
The structure of the bit can be made into a double-edged or single-edged belt structure to improve tool life and drilling quality, or can be used in the internal cooling structure, more efficient cutting
Aluminum bit: Suitable for efficient drilling of various aluminum alloy materials
