@ mohitjindal

u right !!!!!!!!! it need to use more blades to cut small area on aluminium.
Is there any other blades from DREMEL?

I too agree with the need for a more robust cutting disc. Even for a minor cutting job, u run through a number of discs.  I use it at time to cut small strips of wood ,but even if there is a slight misalignment, the disc disintegrates into pieces. I always wear eye protection to avoid being hit by these flying pieces.

Hope Dremel Manisha is reading this

Yes the discs do crash quickly, probably that is why they give sell them in boxes of 30 .
I feel, a steel disc will blunt out too after cutting softer materials etc, atleast these discs do not lose their sharp edge unless materials like mica get burnt and fused on the edge.

The primary reason for the breakage that I feel is unsteady hands (due to vibrations or scare). I try to minimize these breakages by

1. analyzing the edge for optimum cutting angle and then using the tool
2. cutting smaller sections rather than a continous cut
3. giving some dwelling time to the motor for attaining speed and some cool down time after each cut
4. Always remembering that the Dremel is a rotary tool intended for less torque and more speed, so pushing into a cut will break or dull the wheel easily, due to extra heat generated. Just touch and let it have more cycles on the surface to be cut rather than pushing it in like one would for an angle grinder.
5. having loads of patience.
6. Use two wheels together for cutting harder materials
7. cutting at the right RPM (consult manual). More RPM = more heat, which is the biggest enemy

Doing all these had actually increased the life of the wheel, In fact, I've used the last three wheels to the extent where they've been ground down to almost 3mm radius.

Hope that helps.

Thanks Girish,

Your comments have been very helpful, especially the idea of using two wheels together. You were spot on when you commented on the main reason for breakage was due to unsteady hands. I also found that, whenever the cut deepens more than a couple of mm, the risk of breakage increases. I too have improved but have yet to wear out a disc. Thanks once again & will follow your guidelines.

Some more techniques that I've felt help:

8. When cutting wood, hard plastic or iron (any other material that leaves behind loads of mess), keep blowing while the cut is underway, helps remove unnecessary filings which can add to friction. You will notice the moment you blow, the cut seems smoother

9. Mark the edge to be cut by lightly running the dremel once and then deepen the cut,equally applied to cutting coroplast with blades. Less pressure, more runs is the key

  great tips by girishsarwal thanks a bunch sir

This is available only in US.

Pls let me know your city.

Don't waste your time visiting Dremel India website. Not a single button is working.

i bought my dremel 4000 online from Machpowertools, based in Chennai. Their service is commendable.

I agree with pline..Got my Dremel 300 from them as well. Good price and great service.

This response comes after many years of your remarks. My excuse is that I "discovered" rcindia.org just recently. You're right when you remark that the Salespeople of Bosch cannot contribute anything regarding Dremel. But this is the story regarding everything in India. From clothes to nails to tools to even food. The hobby part is perhaps the worst simply because in India gossiping and standing for hours and repeating the same trash over and over again is a hobby in itself. The main subject is money, money and money then somewhere come girls but rarely books and hobbies not at all. So why wonder. When I ask for a particular color in case of a shirt, I will be shown everything but what I want. This is sadly the story about India, Indians and their commonsense. Sorry I have to write this but wage earning is more important than knowing what one is doing. The hobby market in the USA is anywhere between 200 to 500 BILLION Dollars and the trend in Europe is not very different. That is also the reason why there are huge DIY stores.
Now just two ideas: How about packing material, mostly good quality of pine wood. Ingenuity can help you make a lot of money and fulfill your "Hobby".  The other idea is converting beer bottles into wonderful utility items. (The scrap buyer pays Rs. 0.50/bottle).
The ex-chairman of Daewoo Corporation has written a wonderful book called "Money lies on the road" - my addition "Bend your stiff back and pick it up".

This post shows an extremely condescending attitude.I think it is unfair of you to make such overtly general statement about Indians. Comparing the hobby market here to nations such as the USA is pointless. Rather, you should support the effort of Local Hobby Store owners who cater to a small market at low profits. The very presence of this forum is proof that the RC hobby scene in India is progressing. I do not understand what you have written about packing material. What are you trying to say? What does craft out of beer bottles have to do with anything? Please clear this up because I have not understood.

Sir I am proud of being an Indian, and more over having had the guts to give up my 7 year old job, as a systems engineer with the largest software manufacturer on the planet to start my own model railway manufacturing & exporting company (perhaps the only one of its kind in India and definitely in my home town Calcutta). Although its does not earn me any more than my daily bread, yet its a passion I will live and die for.
I encourage others to join the band wagon and proudly say what it says on my home page  "MADE IN INDIA".

"I remember your words again today."

I wonder what those pearls of wisdom were. I don't remember them.........................

VC bhai How would you now  

Those were pearls of wisdom after good dose of nectar.

I hope you remember our discussion  about our friend Peter Scot.  

Dear Niranjan Paul aka pline,  that is so heartening to go thru your post   and VC Sir's response . Actually, I wanted to visit your place in one of my visits to Durgapur but the visits themselves fell through as I left the Institute  . Any way, I hope to come to you  just for the hobby's sake n my sake some time later, God willing .
I don't recall whose quote it is, but its something like this : ' Try and light even a single lamp / light instead of sitting cursing the darkness around you.'
Good Luck.
