Wait a minute, put that drill down. Don't buy that cheap no-name power tool, it'll break within the year and you'll have to buy another. Just grab a Bosch GSB 13 RE in either 230v, or 110v for site work, and you'll have a highly competent, and cheap, power drill.
The GSB 13 RE offers 600w of professional power, hammer action, a 13mm chuck, forward / reverse, variable speed, and a 3 year guarantee if you register online with Bosch.
You see, the GSB13RE is part of Bosch's professional range, so the build quality is much better than the unbranded drills at the big sheds on the edge of town. Pick the drill up and you can feel the balance It may not be the most powerful tool, but if you're after a high quality budget power drill, you can't go wrong with this Bosch.
The Bosch GSB 13 RE can drill up to a diameter of 13mm in concrete, 25mm in wood, 10mm in steel and 15mm in masonry. Thats enough for most DIYers, and is very useful for pro users too. Recommended!
