Topic tags/keywords: question drill press

Is it possible to sharpen forstner drill bits professionally or is it more economical to buy new ones? I have been using a few bits to drill through mesquite and mulberry (for peppermills) and noticed that I am not getting nice curls but more of a dust and the bit gets very hot.
Where would one send the bits to be sharpened, I saw a few youtubve videos but not sure I trust their advice. Any help would be very appreciated.

Capn Eddie does forstner bits. I trust him, but I haven’t tried it.

Are you watching your speed? The bigger the bit, the slower you want to go. Mine have the speed printed on the bit.

Forster bits are pretty to sharpen with a diamond cutting wheel on a dremel.

Just look up “sharpening service”, usually only a couple bucks apiece depending on size if you go that route. The few I know you can ship to and they’ll ship it back, prepaid of course.

Hell, at least one around me has drop off/ pick up points since the area they mainly serve is 60 miles away.

Yep, diamond wheels on a Dremel!!! You can get ‘em at Harbor Freight. I buy them when they are on sale and stock up. They last a surprisingly long time though and you can turn them over to the opposite side when one side is dull. It is quick to do and I even do it on new bits as they usually aren’t sharp enough for me.

If you are drilling really hard woods, you probably should be using carbide tipped fostner bits. MLCS has fostner bit sharpening kits. They always have free shippin. Great place to deal with.
