Abstract: A drill bit of the multigroove type has a shaft with at least three flutes forming respective lateral cutting edges and as many generally radial frontal ridges, one of them extending to or possibly beyond the shaft axis while the others terminate short of same. Each frontal ridge forms an outer and an inner cutting edge adjoining each other at an obtuse angle in a forwardly pointing peak, these peaks lying at different distances from the axis. The peak closest to the axis is axially foremost and the corresponding inner cutting edge includes the smallest angle with the axis to act as a centering blade; with more than three ridges this centering blade can be duplicated in diametrically opposite positions. The outer cutting edges all lie on a common conical surface centered on the axis.

Abstract: A vehicle suspension system includes front and rear wheel suspension assemblies (1,2) for resiliently suspending the wheels of the vehicle. The front wheel suspension assemblies (1) and/or the rear wheel suspension assemblies (2) have a variable suspension characteristic which is controlled in response to changes in steering angle, the steering operation being changed in a direction toward an oversteer characteristic as compared with the steering characteristic during non-steering operation. Specifically, the suspension characteristic of the front wheel suspension assemblies and'or the rear wheel suspension assemblies is changed to make the ratio of the suspension rate of the front wheel suspension assemblies to those of the rear wheel suspension assemblies smaller during steering operation than during non-steering operation. Also, the steering characteristic of the vehicle may be further controlled such that the understeer characteristic of the vehicle is stronger at high speed than at low speed.
