lead machining

[Collin Weisz]

Having problems cutting lead-tin alloy with metal cutting circular blades one inch in diameter. Need to cut grooves about .045 in. tried wd-40 didnt help much-metal wants to smear doesnt cut clean tried various speeds the rotating blades work better than a single cutting edge any help?

I am not familiar with that material but I would use cutting oil for a slitting saw. What do you have your RPMs set at?
