Stephen spivey 1 Posted September 21, 2020 Share Posted September 21, 2020 I made a set of single jack drill steels for hard rock drilling competitions. The are made from s7. Sent them to phoenix heat treat to have them hardened . Problem is I had them harden the hole tool/ tools. They work great . The working end is just right . The other end that the hammer strikes is to hard and starting to chip. Can I take some of the temper out of this end / soften it up a bit? I was thinking a wet rag over the working end and heating up the striking end ? Quote Link to comment Share on other sites More sharing options...
