Abstract
A boring head has a connecting rod, an extending bracket and a cutter mount. The extending bracket is detachably connected with the connecting rod. The cutter mount is securely connected with a front end of the extending bracket. Because the extending bracket is detachably connected with the connecting rod, the extending bracket is replaceable, and the length of the extending bracket can be changed to make a bore with a desired diameter.
