Hey guys, my neighbor is selling a 16 pc & 8 pc Forstner bit sets. I googled them and don't get anything about the quality of that brand. Anybody ever heard of this brand? He's asking $60 for all 24 pieces. Two sets (16 & 8), each in a nice box with dove tailed corners. Don't appear damaged, all have plastic blade guards that are very tight (? not removed much).

Also has this 3.5 HP Craftsman Routher ($50) and a 6ft Craftsman Turning Lath ($150).

I worry about parts availability. Any thoughts.

Ok guys, since this is a garage sale event & another guy just bought the lath and is asking about the bit sets, I pulled the trigger and gave him $45 for both sets. Now that I'm looking at them a bit closer, I don't see any chuck marks on any of the bits except the 3/4". And it is barely noticeable.

A couple more pictures, and that is not rust on them. Looks like that sticky grease the factory puts on them.

Anyway, still curious if anybody has ever heard of this brands quality factor.

Thanks Mike, I found that page also. I live right across the street, so I came home and did a quick google search. It's links back to E-Bay. I did tell him about it. He called his dad to ask about them. His dad said not to sell them for < $100, that they were very high quality bits.

Funny I can't find anything on the net about them other that a few online private sellers. Nothing on the company. I did find one set that the seller said was still in the factory packaging and even had the original sales receipt dated in 1958! My birth year!

I think they will serve you just fine. I have a set from Harbor Freight. At some point, the 3/4 and the 7/8 and maybe one or two more just weren't cutting the mustard so I replaced them individually with Freud. Each time I would go to the local Woodcraft, I would pick up one or two.

Those big bits should come in handy.

I think Carb tech is more popular down under than here. I have a few router bits and they seem okay. The box and writing appears Chinese. I bought a cheap Chinese set at a woodworking show and they aren't very sharp. I can use them in a drill press okay but handheld is hard to get them to cut. I have been able to sharpen them and improve the cutting action but that takes time. Maybe your's are better than that. The sets are still worth having because you have a lot of sizes at your disposal for a small price compared to what a full set of high quality ones like Lee Valley's would set you back.

There are some other advantages of having a cheap set too. I was drilling out some cup holes last week for euro style hinges and these ones seemed to have a deeper cup than normal and by the time I had the hole deep enough the pint was showing through the other side of a 5/8" thick door. I have an expensive carbide bit for the job that is 35mm and 1 3/8 is almost identical in size. So I took the 1 3/8 one out of my set and ground the point off. Doing it on the cheap one didn't hurt a bit but doing that on my expensive one would have.

Some time ago I succumbed to the low price of these boxed sets of Chinese Forstner style bits and they were hopeless, several had to be sharpened before they would cut. I now have individually bought bits off Ebay, all but the BIG ones are Tungsten. Whilst they are still from China, I've never had a problem.

I bought a cheapy set to use occasionally in the drill press. I found that the shanks are out of round with the cutters. I found that if I rotate them around and chucked them up that when I found the spot that they were chucked up to grind the cutters,I marked a spot on the chuck and the shank of the bit with a sharpie to always reference the position for future set ups. It has worked well for me. I too bought a set of diamond files for sharpening the bits to touch up the cutters and they are working OK now.

Thanks fellows, you guys always have great advice. If they don't cut right, there is a sharpening company that Freud recommends in Ocala, FL that does Forstner bits. I'll call them for an estimate...I can only imagine what that may cost! Even is it is only $5 to $10/bit, there are 24 bits! We sill see.

I popped some years ago for a 16 bit set from Rockler. HSS, and work like a champ. Bought diamond sharpening sticks in several grits, but do occasional touch ups rather than allowing them to get dull. Really nice to have them for the drill press, but I'm not able to hold them steady enough to use freehand. Anyone have any suggestions for some kind of plunge type device to steady the drill in hand held situations?

Got curious, so started googling. Found this. Simple, and looks like it would work.

Dunno how it would work, not tried it, but did just read that using a brace with Forstner bits is quite successful.

When I first had the idea I thought it was going to be really simple but then I found out that all three sets of Forstners I have have metric sized shanks and I don't have a set of metric sized bits but it was a fairly quick work around to solve that. I used 3/4" ply and the ply is thicker than the Forstner rim is high and that is a requirement for making the jig. The bit I made the jig for has a 15mm shaft which is slightly smaller than 5/8" so I drilled a 5/8" hole through one thickness of the ply and then took it over to the cut off saw and roughly cut it through the middle of the hole. Then I drilled another piece of the ply with the bit I made the jig for. (Not sure what size it was, I never looked). With bit still in the DP and lowered into the hole it made I used some hot melt glue to stick the two other pieces of ply tight against the bit shaft. All that's left to do is clamp it in place. If you need a precise location then dimple the spot where it needs to go and you'll be able to feel when it's in place. The hole I drilled is as far as it would go without removing the jig and getting rid of the chips but it's no issue to relocate the jig to the same spot to drill deeper. The pictures tell the rest of the story.

I just finished building a vanity for a downstairs bathroom Harry where the drain pipe had to come out the side into the toilet's pump tank (macerator). I measured the location as accurately as I could but when I went to install the vanity I found it didn't fit flush against the wall which put the hole about 6mm / .25" off. I was using a hole saw but it is basically a continuous rim like the Forstner so the same type jig works. I clamped it onto the vainity and was able to enlarge the hole to where it needed to be. It would have been impossible to do that free hand.

Harry I was going to reply back when I saw this that 99% of the time I also use a drill press when I use a Forstner. A few times I've used them freehand, for drilling plug holes I think. However, getting them started without the bit skating around on the surface, especially the larger sizes, can be quite tricky. That jig is just another weapon in the arsenal to get jobs done. If someone needed to make a very accurate hole in a location where a drill press is impractical then they now have the idea for a quick and cost free jig that will get the job done for them.

In my early post I forgot to mention that a few years ago I bought this set of sawtooth Forstner style bits off Ebay, I can't remember what they cost but I do remember that it was cheap! Unlike the much earlier smaller set from Carbar-tec which were hopeless, these work extremely well but even so if I have a Carbide tipped one of the same size required, then that is what I use.

Harry, that set looks very much like one of my cheap sets, only mine came in a fancy wooden box with plexi windows. Mine came with the 'Mastercraft' (Canadian Tire) brand name. I like them but then I've never experienced 'good' bits.

That set of stepper bits also looks identical to my 'Mastercraft' cheapies... great for drilling plexi.

For a jig, I simply cut a hole in a piece of 2x material (on the drill press) that I could clamp in place. Might not work for every situation, but it did help guide the bit.

Note: Check out the picture. I was repairing a goof up.:surprise: I had lost focus and pulled the router out of the hole while it was running, and before retracting the plunge! It quickly tore up the hole and broke the bit. :frown:

The repair worked great.
