ok im thinking on getting a die grinder , i already have a Dremmel but it seems kind of Dinky not enought ***** to it ....i havent tried it but i would figure its for less stressfull things like hobby stuff , IS there any other electric Heavy duty grinders , or should i just go with the air Die grinder?????? and watcha guys think of an Angle head die grinder? yes? no? harder , or is a regular easier to hold etc .

 

I exclusively use a small 25,000 RPM 1/4 air die grinder supplied via a 54 CFM 2-stage air compressor and carbide rotary grinding bits.

I would not use an angle grinder. That is asking for trouble... they are too big for the delicate work of porting.

 

I've been playing around with streetporting and have been very happy with a combination of a 1/4" die grinder with some 6" double-cut carbide burrs I bought on ebay from user mm_tools8rx7 (He was slow as hell about shipping, but the price was right and the bits are nice!) and an old multi-speed Dremel with fine carbide burrs. I use the die grinder for all my runner work and rough port shaping and use the Dremel for the fine work at the edge of the port. The die grinder cuts plenty fast, but it's really easy to go too far on the port opening. With the Dremel, I can shave off as little as a few thousandths at a time. Whatever you do, don't bother with any kind of grinding stones. The carbide burrs may be spendier, but they cut much more quickly and leave a much nicer finish.

 

I use an electric die grinder made by Jepson. It looks like a larger Dremel. I personally hate air grinders due to their sound, and the fact that I don't have a compressor.

As for the use of stones, I quite like them. I do all the rough work with stones, then finish off with paper sanding rolls.

 

I ported my waste gate with a Dremel & a carbide burr.
It was just what I happened to have.
It took about an hour.

 

The 1st time I ported a wastegate I did it with a dremmel, and a combination carbide bits and grinding stones.. It worked pretty well, but was slow and tedious. I now use air tool, and like them alot more.

 

i ended up buying on ebay off a guy who has a store called Odies tools and stuff , odie is his ebay name .......... i bought a micro die grinder , it hits 56,000 rpms an is as thin an small as a Pen , works Realllly nice i like it , it was hard finding carbide burrs that rate over a 56,000 rpm range and that are 1/8 collet ,

 

Interesting. Is that air or electric? Does it have a brand name? Sounds kinda like a dentist's drill...

 

its air , the brands *central pneumatics* heres the specs ............collet size 1/8 .....air inlet 1/4"-18npt..................Maximum air pressure 90psi.......max rpm 56,000........air consumption 2 cfm@ 90psi

 

LOL now that you mention it , it does look like one its really skinny .......

 

heres a pic

 

Sweet! It's available from Harbor Freight for $15. I'm absolutely getting one for detail work. No more Dremel for me! Thanks for sharing...

 

I'm somewhat suprised you haven't built one out of straws, a couple two liter bottles and some fancy electronical stuff :P

 

Dremel all the way!

 

hahahhaha
