May 16, 2005 The thread mill can place threads closer to the bottom of a blind hole, and it can machine threads in big holes with ease. The thread mill leaves room for chips to fall away. And the thread mill, unlike a tap, can combine various hole-making operations into a single tool. In short, there is a great deal that a thread mill can do.
Sep 01, 2012 Harvey Tool offer standard through-coolant thread mills as small as 10-32 and as large as -13. Advents Hartford gave this example. Say you need to cut a 6-12 thread and then a 5-10 thread. Using an inserted thread mill, all you need to do is change inserts from the 12 pitch to the 10 pitch at $30 per insert.
The grinding company can also work with the mills to obtain the material needed, including any special requirements. Also, a grinding company that buys metal in quantity can provide stock to customers who might need an amount of material that is less than a mills minimum order. Sometimes the mill will refer a customer to a grinding house.
