5inch (12.5cm) wide by 28inch (70cm) long allows you to be standing whilst drilling the holes in soil.
Being a larger auger it is recommend you use a High Powered Variable Speed 240v or petrol powered Drill (13mm chuck) with side handle and clutch to protect you against kickback.
It has a common 13mm (1/2inch) hex head.
NOTE: We don't generally recommend this size Power Planter for home garden use. This is a professional grade auger used by Landscapers and does require a higher spec Drill and previous knowledge with power tools.

N.B. We hope it is pretty obvious... but we better say it - The price does not include the Dewalt Drill shown in the demonstration images. The Power Planter can fit onto any standard Australian drills with a 13mm chuck. (eg. Ryobi, Bosch, Black and Decker, Hitachi, etc )
