Core Drilling Method:  U.S. Patent # 6,675,913

What can be more difficult than drilling holes into concrete?

In addition to being time-consuming (and expensive), it causes pain in your arms and back.

A machine that takes too much time to drill a hole is not cost-effective.
A machine that cannot drill a straight hole every time is not efficient.

As a result, the inventor created his Core Drilling Method. This durable, lightweight device is easy to use and transport. Most importantly, it is more accurate than other devices on the market.

To see the maintenance-free prototype in action, please click here (the video is 1 minute long, and it takes 2 -- 3 minutes to download with high-speed internet).

Additional features include:

• Reduces vibrations, leading to lower fatigue and fewer injuries
• Accuracy -- much more accurate than competitors
• Takes less time -- resulting in lower costs to operate
• Requires less manpower to operate
• Invented by a welding shop owner
• Demand -- for millions of construction workers
• Its simple design means that it can be efficiently mass-produced
• Can be manufactured in a variety of sizes (and colors) to fit any existing drill currently on the market
• Can be sold with concrete and construction tools, and in supply outlets and equipment outlets.

Here's how it works:

The Core Drilling Method includes a resilient mount to connect a hammer drill to a drill press or support frame. It uses a recoil frame to maintain a driving force on the hammer drill. An air blower is positioned adjacent to the core drilling bit for cooling and removal of debris. A screw jack is used to provide pressure to the removable press handle and, when installed, renders the unit moveable. Finally, a remote switch allows operation without being subject to dust and debris.

The inventor has a full-length video that is available to interested parties. Please call him to request it.
