Abstract: A carrying case for drill bits has concave rectangular top and bottom panels pivotably mounted at their rear long edges to a narrow, rectangular hinge strip and fastenable at the front edges of the panel to form a closed box. A drill bit holding block extending inward from the inner surface of the hinge strip contains a plurality of parallel bores disposed perpendicularly downward from the flat upper surface of the block. A longitudinally disposed slot cut through the rear surface of the block communicates with each bore. An elastic band looped around the block and lying in the slot is deformable by a longitudinally disposed, grooved compression strip extending inward from the top panel of the case to apply compressive holding forces on the shanks of drills contained within the bores in the holding block, thereby securing the drills in position with the box closed.
