The elongate rod shaped non-impact and non percussion drilling tool comprises: a non-impact and non-percussion drilling tool or implement formation at an outer end of the shank, a portion of the shank having a polygonal cross section at a location on the shank other than at an inner end of the shank, an annular groove in the shank which is only wide enough to receive a detent to prevent axial movement of the tool when it is received in a snap-in chuck assembly and a spline formation at an inner end of the shank. The chuck assembly includes either a polygonal drive structure in a center bore of the chuck assembly or a rotatable nose collar or an axially movable nose collar whereby a tool received in the center bore is held by friction in the polygonal drive structure or by a rotatable movement or an axial movement of the nose collar.

Abstract

The elongate rod shaped non-impact and non percussion drilling tool comprises: a non-impact and non-percussion drilling tool or implement formation at an outer end of the shank, a portion of the shank having a polygonal cross section at a location on the shank other than at an inner end of the shank, an annular groove in the shank which is only wide enough to receive a detent to prevent axial movement of the tool when it is received in a snap-in chuck assembly and a spline formation at an inner end of the shank. The chuck assembly includes either a polygonal drive structure in a center bore of the chuck assembly or a rotatable nose collar or an axially movable nose collar whereby a tool received in the center bore is held by friction in the polygonal drive structure or by a rotatable movement or an axial movement of the nose collar.
