In getting Mrs. Wonky ready, I needed to counterbore some holes into her seat. This required the use of a Forstner bit. Wiki calls the Bosch bit on the left a “Hinge Sinker Bit,” one of their silly misnomers as it fits the definition of a Forstner except for the fact that it has carbide cutting surfaces instead of high speed steel. The outer knives on the Bosch bit cut through veneer much cleaner then the traditional Forstner bits cutting edges. The Bosch bit is actually the best of the three bits as far as cutting smoothness, accuracy and heat build up. At twice the price though of the Porter Cable set I got yesterday, the Bosch bits will stay at the Bosch store. The Porter Cable bits do a nice job actually.
