I just completed cutting an intarsia pattern of a hummingbird and flowers. I was using 25 tpi blades that the package said were for extra sharp turns and marquetry in soft woods up to 3/4". In the process of cutting out the pattern, I broke 6 blades (3/4" pine). Is this normal or am I doing something wrong? They were craftsman pin-end blades. Are there better blades out there? I have plain end adapters for the scroll saw (older Dremel 16" 2 spd). Any help would be greatly appreciated.
