What is the largest size of drill that will fit the supplied chuck?

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.

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.

Hello Harold,Using 3/16" drill works fine.I would not use any drill larger due to possible strain on motor. Best regards, Paul

Good Question. The chuck is labled .6mm to 6.5mm from the factory. In all honesty, I probably would not use it above 4mm because of power. I am using it to drill #60 holes and 1/16th holes in 1/4 inch lucite and plexiglass and it works VERY well for my purpose. The variable speed is quite effective for my purpose. I use the lowest drill speeds. Tim

I used this tool with a dremel and a ground down 1/4'' drill bit to fit a 1/8" chuck. I drilled over a 1000 holes in 1/4" and thicker leather. had no problems.

Go to brand name of the drill and see if they have a website for replacements

The chuck holds 1/16 inch (0,0625) drills securely. So, I suppose that a 2.3 mm (0.23cm or 0.091 inch) drill bit should be held securely by the chuck.

it will fit a 3/8 chuck (regular) however you will have a problem keeping the whole thing aligned, and not flying out in a hundred deadly pieces....better to do it by hand?....you're safe if you have a shop drill press

While I'm not sure of the exact diameter, The base is too large to fit in either the standard or adjustable chuck for a dremel

Chuck size is the adjustable opening at the end for the bit. This drill has a 3/8" chuck size capability, so you would be OK.

The tool has standard 1/4" drive so you'd have to use some type of adapter to use a drill bit. It doesn't have a chuck mechanism.

Yes, the drill bit portion of this assembly is made for a 3/8" chuck or larger.

Thank you for your question. The largest diameter holesaw that this model is designed to work with is 2 inches. If using a 4" hole saw we would recommend a corded drill. If you have further questions please feel free to contact our Bosch Customer Service Representatives at 1-877-BOSCH-99 (1-877-267-2499).

the chuck is universal, you need to know the spindle size for correct adapter.

The shaft is 5/16. It should fit any full size cordless drill. It works great!

Depends on what you will be using it for and the size needed, but for a drill, the link here would be a good place to start... I have a similar one.Vermont American 17108 1/4-Inch to 1/2-Inch Drill Chuck Arbor AdaptorYou can search Drill Arbor and find them here on Amazon and elsewhere. such as this one which is a different size. 1/2" Straight Shank to 3/8"-24 Threaded Drill Chuck Arbor

Yes. That looks like the one I have with 16mm capacity. The spindle and the Jacobs Taper (JT) #3 don't have anything to do with the size of the chuck key. You could have a chuck that is 1/2" and it be a smaller chuck key but still utilize the JT #3 spindle size.

It will fit any chuck that uses a one inch spindle with 8 threads per inch.

Will work fine with either size chuck. I prefer to use compact lightweight 3/8" cordless drills but as others have said, if the shank fits a 3/8" chuck, it'll certainly fit a 1/2" chuck.
