The force modulation system (10) for a drill bit includes a cutter (20), a holder (30), a holder retention device (50), and a first force member (60). The cutter (20) fits in the holder (30), and the holder fits in the drill bit. The holder retention device (50) exerts a holder retention force in a first direction. The first force member (60) exerts a first force in a second direction. The second direction is angled offset to the first direction so as that the cutting profile of the force modulation system is now variable in the second direction, according to the first force. There can also be a second force member (70) to exert a second force in the first direction for more variability of the cutting profile in the first direction. The second force member (170) can be made integral with the first force member (160).
