Open the CIPO recordAbstract From the Canadian patent
A drill gripping device is shown with an inexpensive and compact design. In one embodiment, an inexpensive and more compact design is possible through the use of a single actuator with a single gripping portion of a drill gripping device. Embodiments of drill gripping devices shown are further reduced in price and size due to a force amplification device such as a camming arm. Alternatively, an increased gripping force is possible using an existing size actuator. A drill gripping device is shown with increased precision in gripping. A pair of gripping jaws are synchronized to improve jaw centering capabilities.

Why it's free to use
- Filed January 9, 2004 and granted December 18, 2012. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended January 9, 2024.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by January 9, 2026.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
