Ammojoe Posted February 6, 2011 Share Posted February 6, 2011 Hello Guys, I have an airpen and the tip is reguarly getting blunt. What method do you find most sucessful for sharpening them? Is a standard dremmel tool with attachments strong enough to sharpen the tungsten carbide? Kind Regards, Joe Kind regards, Joe Link to comment Share on other sites More sharing options...
Auspex Posted February 6, 2011 Share Posted February 6, 2011 Use a grinder (or a grinding tip on your Dremmel), and take care not to overheat the tungsten.

Ammojoe Posted February 6, 2011 Author Share Posted February 6, 2011 I'll try not to overheat it. Most of the attachments seem not strong enough, does anybody know of a place to purchase strong enough attachments? Joe Kind regards, Joe Link to comment Share on other sites More sharing options...
PaleoRon Posted February 7, 2011 Share Posted February 7, 2011 I use a water cooled diamond coated lapidary wheel. Link to comment Share on other sites More sharing options...
jpc Posted February 7, 2011 Share Posted February 7, 2011 Tungsten carbide bits have a hardness of nine. Diamonds have a hardness of ten... you gotta use a diamond wheel. I have in the past found good ones for inexpensive at Kent's Tools. They seem to not have anyone working on their website, so it is pretty user unfriendly. But there is a "send us an email" section. What you want is a diamond wheel for a Dremel. Dremel makes this one My link, but it has holes... me no like for sharpening. These guys (Pfingst) have what you want for a bit more money. They even come in different grits. These are the cream of the crop, as far as I am concerned. Link to comment Share on other sites More sharing options...
Terry Dactyll Posted February 9, 2011 Share Posted February 9, 2011 Joe.... I'm pretty sure Ken mannion does a little diamond disc arrangement to fit a dremmel for sharpening tips... maybe contact ken.... Cheers Steve... And Welcome if your a New Member...
