The anglegrinder is the most versatile metalworking tool, it is the first tool any metalworker should buy. Only the best quality anglegrinders should be used for metalworking, low quality grinders will not only give bad results but you will quickly overload them resulting in a "meltdown". The three brands we can recomend are Hitachi, Makita and DeWalt in that order, be sure to select a high-power model rated over 1000W. The following models are the ones we can personally recomend:

	Makita 9565CV 1400W 125mm
	Hitachi G15YC 1500W 150mm
	Hitachi G13YC 1500W 125mm

The following models from DeWalt should also perform well:

	DeWalt DW825 1400w 125mm
	DeWalt DW824 1300W 125mm
	DeWalt DW827 1300W 150mm

The grinder has to be light and easy to hold with one hand, anything heavier than 2.5kg (7lb) is to heavy for continuous one handed work. Don't be tempted to buy a bulky 2 hand model unless you plan to use it for cutting concrete or asphalt. The power button should lock in the on setting yet be easility released. The 90° handle should be removable and it should be possible to attach on top and bottom of the grinder. A variable speed setting is only used when grinding to remove coatings or rust, even under these circumstances it can be ignored by using the correct grit abrasive wheel.

We have used our anglegrinder to do anything from cutting a 20mm (0,8") thick plate to removing an aluminium heat sink from a microprocessor. As you can see we choose to use the angle grinder without the cover, if you do this it becomes even more important we wear good eye protection. We have also replaced the original cord with a longer (3m, 10ft) rubber shielded cord. The wrench can be safely stoved away, it is much quicker to fasten the blades/wheels by hand.

The wheels/blades make a huge difference in both quality and speed, we mostly use Wurth and Sait. The Wurth wheels have performed very well and come highly recomended, the higher price is offset by better durability and better performance. When using blades for cutting it is advisable to choose the smallest thickness available (usually 1mm), there is no advantage in using thicker blades unless cutting slits.
