Carbide Fostner Bits???

I’ve used Freud. I’m not really aware of any others, except for boring bits made for CNC machinery with 10mm shanks.

I also have a Freud.
It holds an edge a lot longer than HSS.
I have to ask…What are you making with the billiard balls?

I got a Rockler one for hinges, works A+’
If you are drilling high density acrylic alot I would go for it, carbide isn’t as sharp but will last longer and I have no idea if you can resharpen those HSS bits without changing the size.
I have a carbide bandsaw blade that will hog through any wet or knotty log and keep going and going.
You might be able to diamond hone carbide without changing the size also.

ha ha…you mean “little people”

Here’s a page from Germany listing Famag’s carbide tipped Bormax3 Forstners about half way down. http://www.fine-tools.com/bohr4.htm They’re bloody expensive.

Here’s a set of carbide Forstners from Woodtek costing about 1/4 of the price: http://woodworker.com/fullpres.asp?PARTNUM=109-094&LARGEVIEW=ON

It’s quite hard to figure what’s what. There’s lots talked about the advantages of the much tougher higher quality fine grained carbide – but i never seem to be able to tell when it’s about paying for the brand, or about paying for quality.

I recently ended up buying a set of 15 of Famag’s series 1622 HSS Forstners, they were still very expensive but will hopefully be worth it – the carbides were just too rich for me….
