Drill bit extensions for rotary hammers and drills
A drill bit extension bridges the distance your machine cannot reach on its own, so you drill deeper or work in awkward spots without breaking open the wall or floor. You will find them with SDS-plus and SDS-max fittings for rotary hammers, alongside adapters that connect a different fitting system to your machine.
The right extension depends on the fitting of your bit and on the working length you need, which ranges from a few centimetres to well over a metre for pass-throughs in thick structures. Mind the stiffness: the longer the extension, the more a close-tolerance fit matters to prevent wobble and bit breakage. Brands such as Milwaukee, Bosch, HiKOKI and Makita supply extensions and adapters that fit the common rotary hammers.
Choose a length with some reserve over your standard job, and check that the fitting matches your machine and bit exactly, so the connection does not develop play or seize up under load while you work.
