Placing an order with KBC Tools unfortunately their web site doesn't show me individual stubby metric HS drills other than sets.

Require KBC's part number for 3.30 HS metric drill bit, anyone have a more recent KBC catalogue kindly post their number on same.

Beautiful spring day in MJ.

@David88 got you the right diameter but its a jobber (regular length) if that matters. I think I was down this path before & I don't recall much selection in stub length + metric combination. Only IMP fractional & numbered, individual or sets. I'm not sure if they are phasing out the paper catalogs? I haven't received one in years.

If you can find close diameter size, they call them stub, not stubby.

Sometimes they are called screw machine drills but maybe KBC lumps them together

From Vol. 52 (circa 2020) Jobber length is 1-091-0330
I don't see metric screw machine or stubby drills anywhere in the paper catalogue.

That said 3.3mm is 1/8" so that's an option

3.30 mm bit = 0.1299 " - 1/8" bit = .1250" - #30 " bit = 0.1285 "with the latter being a closer option just saying

Last several years I've been able to buy metric stubby drill bits listed on their web site, what has happened???

Try calling them as Degen suggested.

@Dusty you might be aware but just in case, screw machines / stub drills are predominantly 135-deg point angle. Screw & CNC machines have no issue with this because they are usually more rigid, less play & CAM can be optimized. For manual mortals like us, best practice would be to spot drill with a same/larger included angle, unfortunately finding these are rarer & more expensive. So a more common 120-deg spot followed by a more common 118-deg point might actually lead to a more accurate hole than a spotless stub +/- a bunch of variables. Or buying an offshore carbide for the price of domestic HSS. I mention this because you specifically wanted a shorty, presumably for a reason.

If you have a bit of free time, good metric drills can be had quite reasonably, although it can be a crap shoot sometimes. Unfortunately many come in 10 lots. I've wanted some incremental decimal metrics myself for various applications so been dabbling with different vendors.

Just did a search on the KBC sight - 3.3 mm Stubb HSS 1-904-0330 $1.45, and 3.3mm Parabolic stub cobalt 1-148-089273 $10.16
I can't find the first product on the Canadian site. Were you on the US site?

Edit: I corrected the part number in Larry's post.
