An original Dremel has 35k RPM and is available for around 10k at the Hardware store in Heera Panna at Mahalaxmi in Mumbai . Remember to buy lots of blades as they wear off pretty fast.
I bought it 4-5 years back through a TV commercial And its POS. Stay away. The motor does not have enough torque to cut through even aluminum, so forget about steel. (used in most cases these days). And mind you i used imported reinforced cutting discs.
