Abstract
The drill bit has a hard metal plate (12) extending through a slot in the drill bit tip, where it is anchored. This plate has an envelope curve (20) with a tip angle of about 130 degrees and a hard metal tip (28) lying within the envelope curve. The tip angle of the hard metal tip is considerably less than 130 degrees , in the region of 90 degrees . The main cutting edge (30) of the plate extends across the tip. The plate has a necking towards the tip springing back from the envelope curve.
