Has onyone used any of the 18V corldess hammer drills for bolting in blueies sandstone? They're so much lighter and cheaper, for example Bunnings sell a RYOBI one for about $150 (without the battery or charger) or they sell an OZITO, with batteries and charger, but no SDS chuck for less than $100 (buy non sds bits and add $20). These two corldess hammer drills are only 18 Volt. Is this likely to be good enough to get in 6 to 8 bolts per battery? |
