I think that a 1/4" bit will fit into the chuck, but the motor doesn't have the torque to push it through anything harder than wax. This machine is a sweet running little drill press, but it is seriously lacking torque. It is only for drilling very small holes in light or thin material. It took me several minutes to drill a 1/8" hole in 1/4" aluminum. Good machine for what it's made for.

I measured 1.25...but what is important to understand is....Why do you care??? You will NOT be able to use any of the bits you have if they did not come with this unit. It is not the size but the way the bits are machined that make it specific ONLY to this tool. For the price you can't beat it..but don't expect to just use your other bits or just go to Home Desperate and find a replacement bit. It ain't gonna happen.

Not trying to be funny but a 3 (1/2) inch hole saw should make a 3 (1/2) inch hole. Just for curiosity I measured the hole saw blade and this particular one measures 3 (7/16) inch outside and 3 (5/16) inner. Wall side for teeth is (1/16) inch thick. Suggest you look for a 3 inch hole saw and use oscillating sanding drum disk to get to the 3.06 needed.

I'm not familiar with the drill but you just need to know if it is a taper fit and if it is what size this one happens to be a JT33(Jacobs Taper 33) is all that means. So once you find the taper your drill requires then you can decide how large a bit you want it to take ie: 3/4 or 5/8 ths are two popular sizes. Some drills use a threaded chuck so check which yours has and go from there hope this helps !!

The largest drill size in the spec's is 1/4" or 6mm. That size is really too large for the structure of the machine. The spindle runs very true with less than 0.0001" total indicated runout and I tested the chuck with 3 sizes of drill [minimum, 1/8" and 1/4"] and the TIR for all was 0.0032" which is VERY good for a small Jacobs type chuck.

Moosie, This bit will make a hole as deep as you want provided you have a drill / press with a spindle long enough. In most cases the limiting factor to hole depth is not the actual bit, but your setup. The bit will bore its way to China (or ostensibly to the USA if you happen to live in China) if you have a way to push it that far (and keep it from melting). The bit itself is 3-1/2 inches long (end to end). Hope this helps.

Yes, it's designed for 3/4" holes. In a 3/4" hole it's a little loose so if you have a drill bit just a tiny bit smaller (probably metric), try that. It's much more stable. BTW, the things work beautifully if the piece you're holding has flat edges. If they're rounded at all, the work piece will jump all over the place.

Sorry, I guess, could not understand your question well . In the item description they have mentioned size of all the bits. This set has 1 bit of 5/16, 1 bit of 3/8, 1 bit of 1/2, 3 bits of 1/4 (Various length) and 1 bit of 3/16... hope it helps.

I don't know what the hole size is.It's made to fit the Dremel Saw Max. Not "any" Dremel tool!

If I recall correctly, it's 4 1/2". I use a hole saw of that size (pretty sure that size, bigger than you think it should be) but can be done with a saber saw.

Hello; The bit that I have fits into a 3/8 drill easily. I believe my bit is the same bit you are asking about. Good luck.

The drill bit doesn't have the size labeled on it. I used a caliper to measure it and it is 0.245" or converted to mm 6.223mm

Hello, I tested by inserting an actual drill bit: the 3/16"-1/4"=perfect, the 5/16" would be max size, however, clip will not sit flat as in the photo.9/32"?

I have seen a number of questions regarding the drill diameter capacity of this drill's drill chuck. So, in order to finally put these drill diameter questions to rest, I have measured the smallest and largest diameter drill that will fit this drill's drill chuck. Drum roll, please . . . The SMALLEST and LARGEST drill sizes that will fit into this chuck are a 1/64" [0.039mm] (smallest) and 9/32" [7.06mm] (largest) diameter drill bit, respectively. Hope this helps . . .

4 to 5inch. It will fit a 1/4in drill bit and u will have enough room to drill into the the wood
