Abstract

A self-lubricated drill block comprises a housing, a reservoir, and a drill guide. The housing includes at least a top surface, a bottom surface, and a through hole extending from the top surface to the bottom surface. The reservoir is positioned within an interior of the housing and is configured to retain a lubricant. The drill guide is positioned within the through hole and is configured to receive a drill bit. The drill guide includes a cylindrical side wall which includes a lubricant opening through which the lubricant is received and supplied to the drill bit.

First claim

Having thus described various embodiments of the invention, what is claimed as new and desired to be protected by Letters Patent includes the following:

1. A self-lubricated drill block comprising:
a housing including at least a top surface, a bottom surface, and a through hole extending from the top surface to the bottom surface;
a reservoir located and sealed within the housing and configured to retain a lubricant; and
a drill guide configured to receive a drill bit, the drill guide positioned within the through hole and including a side wall, the side wall including a lubricant opening through which the lubricant is received and supplied to an intermediate portion of the drill bit within the drill guide.

2. The self-lubricated drill block of claim 1 , further comprising a cap configured to couple to the housing and seal the reservoir.

3. The self-lubricated drill block of claim 1 , wherein the drill guide includes a bushing with a head of greater diameter than a diameter of the side wall and the self-lubricated drill block further comprises a lock screw configured to fasten the head to the housing.

4. The self-lubricated drill block of claim 1 , wherein the lubricant opening includes a hole that extends radially through the side wall.

5. The self-lubricated drill block of claim 1 , wherein the drill guide is threaded on an outer surface and a surface of the through hole is threaded so that the drill guide is threadably coupled to the through hole.

6. The self-lubricated drill block of claim 1 , further comprising a lubricant channel coupling to the reservoir at a first end and to the lubricant opening at an opposing second end, the lubricant channel configured to supply the lubricant to the lubricant opening from the reservoir.
