Hello. Was looking at getting a cordless angle grinder for handiness about a farm and can take about unlike corded. However what's best make to go for and also bearing in mind that the brand's other tools are good quality if buying other tools I could use the battery. Thinking of going for a 6 inch as may aswell go for a bigger size than 115mm and have power when going to the cost of cordless. Just for general farm work we bit of cutting and sharpening. Thanks
