I would like to use it to increase the durability of my cutting tools, is this possible? The types of cutting tools are key broaches, hobs, and end mills, all HSS steel.

I understand that the types of cutting tools are key broaches, hobs, and end mills, all of which are HSS steel,
Bell Hammer can also be used for various metal tools including HSS steel.
This product forms a highly lubricating film on the metal surface of cutting tools to reduce friction and heat generation during cutting, which is expected to reduce tool wear and extend tool life.
