US 2020/0047327 A1 · Tool Bit Storage System

Abstract

A drill bit cooling system is provided. After drilling use, the drill tip of a drill bit reaches higher temperatures than a shank or flute of the drill bit. Compartments are provided that are sized in length and width (diameter) to accommodate the drill bit and a cover or back plate with an increased melting temperature facilitates the storage of hot drill tip. By using different components to construct the drill bit holder, a lightweight and versatile cooling system permits the drill bit to be rapidly interchanged on a power tool or drill, without melting through the storage device. This helps the operator interchange drill bits while working on a workpiece without waiting for each drill bit to cool prior to storing and replacing the drill bit.

a first end located opposite first opening along first compartment axis;
and
a first material having a first melting temperature;
a second compartment extending along a longitudinal second compartment axis parallel to first compartment axis, second compartment comprising:
a second opening;
a second end opposite second opening on second compartment axis;
and
a second material having a second melting temperature;
and
a cover plate coupled to both first and second ends perpendicular to first and second compartment axes, cover plate comprising a third material having a third melting temperature that is higher than first and second compartment melting temperatures.
