How to use regular drill bits with Ozito 1500w Rotary Hammer Drill?

[nikkinik]

Hi folks, I got my partner a rotary hammer drill as we will be installing a gate shortly and will be drilling into concrete.  Our old corded 710w drill had died so I got this one as a replacement/ upgrade for him.   However, seems like our old drill bits are not compatible with this SDS+ system… bugger.  

Is there an accessory I can purchase that would let us use our existing collection of regular bits with this new drill? (Please be specific as I’ve googled and am confused).  We also want to use it with our auger attachment as we have solid clay soil and the drill/auger combo works well when digging holes. (This was the cause of our old drill’s untimely death, hence me getting the 1500w version).   Please help?  I don’t want to buy another drill.  We have a little cordless run around one, but this was meant to be the workhorse.

Hello @nikkinik 

The adapter you are looking for is called the Dynalink 13mm Drill Chuck with SDS Plus Adapter and Chuck Key. Please note that this adapter will only accept regular drill bits up to 13mm in diameter. If you are after a larger adapter, please speak to the senior tool specialist at the store.

If you need further assistance, please let us know.

Hi @nikkinik 

Though the adaptor kit @EricL suggests will work, it's not recommended for masonry drilling with normal masonry bits. Neither are designed to withstand the high impact action an SDS drill produce. Doing so can result in the chuck falling apart and/or the tip of the masonry bit snapping off. This is common even with SDS Drills supplied with adaptors.

Regarding using your new SDS drill. These tools are not intended for heavy duty non-masonry SDS drilling applications. This would included large hole-saws, mixing mortars and glues and especially using it to drive an auger into clay as these tasks can result in an "untimely death". This is due to the gearbox system these types of drills have, which don't provide or need to provide high-torque for their primary function of masonry drilling. The normal drilling mode is only suitable for general wood and masonry drilling.

Conventional drills with a 2-speed gearbox switched to low gear are designed for high-torque drilling applications and depending on the model mixing. I would recommend a model with a side handle for extra control and safety. These drills can also be used with a garden auger, can be used in to hard soil. But using it in to dense sticky clay will constantly stall the motor which for brushed motors can cause either the switch or motor to burn-out. Or in the case of electronically controlled cordless brushless models to constantly stop from their integrated safety systems.. 

Old fashioned manual labour with pincers and crowbar is what I would recommend and use.

Hi @nikkinik,

I just wanted to follow up and confirm @Nailbag's warning about masonry bits and that adaptor. That adaptor can be used to convert the SDS drill to take normal drillbits when functioning in non-impact mode. You can't use that adaptor with standard masonry bits in impact mode as @Nailbag has mentioned. Standard masonry bits are not designed to take the impact of a rotary hammer drill. It's best to use SDS bits in it.
