Abstract: An improved drill bit having a shank of larger diameter than the body of the drill has an intermediate section rearward of the point section of the drill of smaller diameter than the point, and a longitudinally elongated, enlarged diameter root section joining the rear end of the intermediate section to the shank. The reduced diameter of the intermediate section provides a clearance space, preventing rubbing of the wall of a hole drilled by the bit, while the enlarged diameter root section increases the resistance of the bit to breaking. An improved method of making the enlarged-root drill bit includes inclining a relieving wheel at a substantially smaller angle to the longitudinal axis of a blank than the angle at which the blank was fluted. In one embodiment having a front tapered tip made by the novel method, rearwardly directed teeth are formed at the rear plane of the drill point, by fluting and relieving steps alone, without requiring an additional machining step.

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.
