Rotary Hole Openers
Rotary Hole Openers are built to your specifications using the cutters of TCI button bits or steel tooth bits.
They can be built with your thread connection of choice, and can also have a thread connection left at the bottom in order for you to attach your own drill bit. As seen in the photos below, you may also choose to have the bottom built like a drag bit. Givens International can also add a stabilizer ring if you choose. There are many variations on hole openers so please call us to discuss your requirements.
