    Abstract: The present invention relates to a method for the manufacturing of drill bits for percussive rock drilling and a rock drill bit (10) and a button (14A). The rock drill bit includes a head portion (11) with a forward surface (13; 15), which has a number of buttons (16) provided in a peripheral wreath, and a number front buttons (14A) placed inside the peripheral buttons (16). At least one of said buttons has a diameter (D) and a height (H). The button (14A) is welded to an essentially flat part of the forward surface. The button is metallurgically bound to the forward surface (13, 15) and the following formula applies: H/D
