Low priced Forstner bits


A local tool store is having a sale on a 7 piece Forstner wood bit package. Regular price is $22.00 Can on sale for $8.00 Seems like it is worth giving them a try for that price. Anyone tried a similar on ' sale ' on Forstner wood bit pack ?
on a similar topic - Has anyone tried those titanium coated drill bits ? They are very brittle and are the worst twist drill bits I've ever used. I will be sticking to HHS bits.

Do they come in a wood box? I bought a low end set in a box. My plan was to use them and replace them as needed but I still have the nice wood case to keep them in. Of the seven piece set, I've replaced the 3/4" and 3/8" as they are the ones I've used the most. The other sizes have only seen few holes and they work well enough for that. It is a low cost way to have a selection of bits on hand "just in case"

I don't know if they come in a wood box.
Very likely these wood bits are made in China of some type of carbon steel , with some kind of heat treat. Since I'm drilling in softwood they don't have to be the best . If I pick up a pack of these el'cheapo Forstner bits then will report how they worked.

I got hooked on the Freud carbide forstner bits. They are so good that I don't buy anything else. I just finished drilling twenty-seven 3/4" dog holes in a rock maple bench top that is 40 years old. Talk about tough! But the freud bit sliced through it like a surgeon's scalpel throwing off fine curly shavings the whole way. When I finished it looked like the holes had been machined.

As they have been! Sorry. Tom

This is what I did too. The bits are cheap and there is noticable runout when spinning in the drill press. But, for making holes that don't have to be exact they're fine. If, you're going to use them for joinery like making mortises I'd buy a good (read: expensive) forstner bit.

Icepick:
I use these quite a bit. I bought a set about 5 years ago simply for the size. They are good for having the exact size you need on occasion, and they are easy to sharpen with the Dremel because the steel is pretty soft. I really only use these for hobby stuff.
But for door hinges, etc., (Blum style Euros) I did buy the exact bit I needed. It did not escape me that the American made Forstner bit for cab hardware cost as much as my "box 'o bits".

If these are made in Asia, chances are that they are not too good and don't expect too much.

I don't think that anyone paying a buck a piece (US) is expecting great quality.. *g*

They're rubbish, but if you don't have them already, it's worth getting them.
You'l also need something like a small diamond hone, because they're blunt as anything when they arrive. When sharpened, they become usable, if not good.

One thing that these cheap Forstner's have a problem with is cutting without the center guide point. (i.e. enlarging an existing hole, cutting a slice near the edge, etc.) You need a drill press for that, and they really vibrate like crazy when you try it.

2 1/8" for $30 US, with the usual intent: start with a cheap collection in a nice box and replace the ones that were used a lot with good ones..
So far, they all still do a great job and if I need more I'll buy the same or a similar set... I was thinking of buying a good quality 2 1/8" for chuck turning, but that would be over twice the cost of another set of cheap ones.. YMMV

No offense, but just FYI: They aren't titanium coated bits. They are titanium nitride coated, which is a micron thin coating applied to the cutting surfaces of the bits. You are right about them being brittle, but this has to do with the cheap steel the bits themselves are made out of, and not the TiN coating. I managed to get my hands on some professional TiN bits intended for machine shop use and they worked great in my drill press. BTW, drill bits aren't the only tool with a TiN coating. High performance end mills for machining are also coated.

Thanks for the information.
Like most tools "you get what you pays for"

the TiN coating is only a lubricant. it is put on the tools to help the ejection of metal chips. it is not meant to make the tool keep an edge longer. it does not really work with wood either. so they are a waste of money. the right drill bit will drill materials faster then the wrong one. for woodworking drill bits with deep flutes will eject wood chips better. but the shape and design of the bit will make the performance difference not the coating.

Actually, it is meant to help keep an edge longer and it works. You are quite correct that it is a lubricant. Helping chips slide off instead of adhering or trying to adhere results in lower local heating and abrasion, making the edge last longer. The difference is quite apparent when machining high strength stainless, titanium, inconel or other tough machining metals. No difference for wood however.

I was not sure about the edge part so I kept quiet (G)

I bought a 7-piece set of Forsners for $20 about 8 or 9 months ago, and they work just fine for me. They're probably not going to last for 20 years, but they're certainly functional, and they leave a nice clean flat-bottomed hole like you'd expect. The brand name was "Columbian"

I bought a set of 16 'forstner' bits from Grizzly for about $30. They came in a nice double-hinged box. They turned out to be mostly saw-toothed bits. Only the three smallest were actually forstner. It doesn't matter to me, they cut great. I don't know what the 'quality' bits cut like but I think the imported Grizzly set is a heck of a deal...
