PM Sent. Scintilla (Swiss) is part of Bosch, lo these many years. They are not what they used to be, but they are all Bosch has of any value besides a global identity campaign. I do not, and will not own a Bosch power tool from any of their other divisions. Bosch bits and cutters are also unpredictable. Some work well. Some are average. Some are not even good ballast.
