Oversize Wire Taps

Finish threads of a blind hole to the correct depth using oversize bottoming taps from Olander. A key piece during the Heli-Coil® insert installation process, our vast collection of bottom taps is available in multiple thread sizes to meet a wide variety of applications. While a bottoming tap isn't designed to create a brand-new hole, it does work to establish an already well-formed tapped hole all the way to the bottom.

Select the bottom tap that's right for your project at Olander. If you're unsure of the thread size you need, you can contact us for expert advice.
