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.

First claim

What is claimed is:

1. A tool pouch comprising:
an apron comprising a plurality of pockets; and
a bit holder placed within a first pocket of the plurality of pockets, the bit holder comprising a first compartment longitudinally extending along a first axis, the first compartment comprising:
a first opening;
a first end located opposite the first opening along the first axis; and
a first material having a first melting temperature;

the bit holder further comprising a second compartment longitudinally extending along a second axis parallel to the first axis, the second compartment comprising:
a second opening;
a second end opposite the second opening on the second axis; and
a second material having a second melting temperature; and

a cover plate coupled to both the first and second ends, the cover plate comprising a third material having a third melting temperature that is higher than the first melting temperature and the second melting temperature.

2. The tool pouch of claim 1 , wherein the first melting temperature is the same as the second melting temperature.

3. The tool pouch of claim 1 , wherein the first material is the same as the second material.

4. The tool pouch of claim 1 , the first compartment extending a first length from the first opening to the first end, and the second compartment extending a second length from the second opening to the second end, wherein the second length is greater than the first length.

5. The tool pouch of claim 1 , wherein the first compartment comprises a hollow cylinder defining a first radius extending perpendicularly from the first axis to an internal wall of the first compartment, and wherein the second compartment comprises a hollow cylinder defining a second radius extending perpendicularly from the second axis to an internal wall of the second compartment, wherein the second radius is greater than the first radius.

6. The tool pouch of claim 1 , the bit holder further comprising a plurality of connectors that couple the first compartment to the second compartment, the plurality of connectors extending along a plurality of planes between the first compartment and the second compartment, such that each connector of the plurality of connectors contacts both the first compartment and the second compartment;
wherein a first connector of the plurality of connectors comprises a bore that extends through the first connector in a direction orthogonal to the first axis and the second axis and between the first compartment and the second compartment;
wherein the cover plate comprises two bent portions that extend parallel to the first axis and the second axis; and
wherein the two bent portions couple to the bore between the first compartment and the second compartment.

7. The tool pouch of claim 6 , wherein each connector of the plurality of connectors is spaced apart from each other in a direction parallel to the first axis.

8. The tool pouch of claim 6 , wherein each of the plurality of connectors extends between the first and second compartments such that each of the plurality of connectors contacts opposing outer surfaces of the first compartment and each of the plurality of connectors contacts opposing outer surfaces of the second compartment.

9. The tool pouch of claim 1 , further comprising an insert coupled to the cover plate, the insert extending into the first compartment and the second compartment, the insert comprising a fourth material having a higher melting temperature than the first and second melting temperatures.

10. The tool pouch of claim 1 , wherein the first compartment and the second compartment are formed from a single integral component.

11. A cooling bit holder storage system comprising:
an apron comprising a pocket;
a drill bit having a bit temperature at a drilling tip of the drill bit; and
a bit holder placed within the pocket, the bit holder comprising a first compartment longitudinally extending along a first axis, the first compartment comprising:
a first opening;
a first end located opposite the first opening along the first axis; and
a first material having a first melting temperature;

the bit holder further comprising a second compartment longitudinally extending along a second axis parallel to the first axis, the second compartment comprising:
a second opening;
a second end opposite the second opening on the second axis; and
a second material having a second melting temperature; and

a cover plate comprising a third material having a third melting temperature that is higher than the first melting temperature and the second melting temperature;
wherein the bit temperature of the drilling tip of the drill bit is higher than the first melting temperature of the first material, is higher than the second melting temperature of the second material, and is less than the third melting temperature of the third material.

12. The cooling bit holder storage system of claim 11 , wherein the first material is the same as the second material.

13. The cooling bit holder storage system of claim 11 , wherein the first melting temperature is the same as the second melting temperature.

14. The cooling bit holder storage system of claim 11 , further comprising an insert coupled to the cover plate, the insert extending into the first compartment and the second compartment, the insert comprising a fourth material having a higher melting temperature than the third melting temperature.

15. The cooling bit holder storage system of claim 11 , wherein the first compartment and the second compartment are a single integral component.
