A reamer is proposed having at least one cutter plate that is held by at least one clamping jaw located in a recess in the head of the reamer and having an opening for a clamping screw.

Why it's free to use
- Filed February 6, 1990 and granted February 2, 1999. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended February 6, 2010.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by February 6, 2012.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
