there are a ton of them on here, all shapes and sizes for any port job you might have. Not sure which one he bought but it ported the exhaust on his 20b in 15 minutes. He has quite a bit of porting experience and these cut through the stuff like butter.

it gets kinda expensive for $5 a piece https://www.nopistons.com/forums/pub...1047683561.gif

You have to get the Carbide bits, Or at least that is what Dave said when he did his. Home Depot sells the bits for $9.99.



I just bought my dremel a week ago. Cool Toy!

get them on ebay! I got a set of 8 for 19 bucks. carbide is a must for porting. Just do a search on there.

Use the guy on ebay, search! there are links to the guy already posted.
