I umed and ared about spending that sort of money on a Fein that I thought I could do without. After a few months, I bit the bullet and bought one from Tile Trader [Forum main sponsor] and have never doubted its build quality and the reliability of equipment. I have worked it to a frazzle on several occasions - continous running - up to an hour or more, never fails.
That said, the blades from fein are expensive, however, Imperial - USA, make and sell a cheaper equivalent for wood and metal which I now buy.
If you want diamond blades, I have developed a 60 grit resin bonded 5mm deep finish on a standard fein blade. 25mm wide, they are about £45 each so they are not for the fein't hearthed [Very sorry about that - just could not resist it] but the perform well.
I been bashing on for years on this forum about ' You only get what you pay for ' and in the main it still holds true - maybe not in the case of Bentley Cars, - oh they are UK built of course, but if you can warrant paying about £100 more for a Fein, it will repay you in a very short while.
Why buy Ford if you can afford a Merc. ?
