I cut out a 5x3/4" round plate using oxy/acet then I ground off most the cut with a grinder.
I drilled a 3/8 hole in the center and mouted a bolt and nut to hold it in the three jaw chuck.
I am having a problem cutting the plate, the bits are getting dull, I am using high speed steel bits as well as carbide and they will not make satisfactory cuts.
Is this happening because flame cut metals are hardening to a point where they cannot be cut on the lathe.
My late is a SB9 using 1/4 in bits.
thanks,
