Quick-change drill bits and holder

In combination:

• a holder with an attached part having an end for insertion into the chuck of a drill;
• the opposite end of said holder being a hollow cylinder, said hollow cylinder hexagonally shaped on the inside of the cylinder, a magnet inside said cylinder recessed sufficiently to receive a hexagonally ended drill bit into said cylinder;
• a "C" ring located inside the cylinder, said "C" ring made of spring steel, said "C" ring held in place by a circular groove;
• said holder further comprising a split sleeve having two portions connected to the holder in such a fashion as to permit each said portion to pivot in an arc relative to the axis of said holder, a shaped flat spring spanning between each said portion and the holder, each said spring being placed on the end of the portion adjacent the end of the holder which is inserted into the drill chuck;
• said portion being attached to said holder by means of a tang on opposite sides of each half of said portion and folded in toward said holder, said tangs fitted inside a circularly centered hole on each side of said holder, each said hole receiving one said tang from each said portion;
• the end of said portion facing the end that receives said drill bit extends slightly beyond the end of said holder and is folded over toward the axis of said holder a sufficient distance to engage the circular groove in said drill bit when said springs are in the extended or "at rest" position, but when said springs are compressed, the said distance will permit removal or insertion of said drill bit;
• the end of said portion facing the chuck is also slightly folded over toward the holder;
• the edges at each side of each said portion have an obtuse angle beginning at the tangs and continuing to the end of said portion that faces the drill chuck.
