Vertical Drilling
Blue Demon company was started in 1948 by Herb Hawthorne as the Hawthorne Bit company. It was the first company to develop a replaceable drag bit for use in drilling water wells, shallow oil and gas wells, and construction holes with a mud rotary drill rig. They were awarded a patent for this product in 1948.
The production facility was ultimately moved to Sedalia, Missouri where it continues to produce the original replaceable blade bits, unitized drag bits, PDCs, BD drill heads (originally developed by Austin Powder), as well as directional pilot bits and replaceable backreamer bits which we supply to numerous OEMs and distributors.
Outside of our own product line, we also produce carbide parts for a number of manufacturers in allied businesses. If you have questions, don’t hesitate to contact us by e-mail, phone, or fax and we will be happy to assist you.
