| 213 | Vibrating percussion bit | US3738435D | 1971-07-29 | US3738435A | 1973-06-12 | BRONSON C |
| A percussion bit for hard rock formations includes a body having a keyhole shaped slot formed through it which causes the body to vibrate laterally as a tuning fork whenever the bit is impacted. Because of the vibration of the body, hardened inserts mounted in the body form a borehole not only by vertical percussive engagement but also by lateral percussive engagement due to the tuning fork action of the bit and by scraping due to rotation of the bit in the borehole. Passageways extending through the body direct compressed air through the bit to remove drilling debris from the borehole.
