Answer to Question 2

Dremel is engaging in a form of metering. Purchasers differ in their willingness to pay for the continued use of the system. Those who value it a lot will purchase many different accessories. Those who have lower willingness to pay are going only get the more basic bits. So, a higher margin for the accessories allows Dremel to extract more of the surplus from the high types without losing the low types.
