Talk:Drill bit shank

History

I've commented out the "development of shank/shuck in conjunction" in the lead paragraph, while at the same time adding a "history" subsection above it. It would be a good addition to this article to have something there.

Partial overlap of content regarding the shanks of other cutting tools

It occurs to me that the content here overlaps largely (not entirely) with what could be said about the shanks of other cutting tools in machining and woodworking, for example, the shanks of endmills and other milling cutters, boring bars, reamers, and taps. I think I may eventually rename this article to "cutting tool shank" and have drill bit shanks be one section among others. But I probably won't get around to it for a while. Just noting the brainstorm here to let it percolate. — ¾-10 16:19, 30 April 2011 (UTC)[reply]

Sounds like a great idea to me. Wizard191 (talk) 18:49, 2 May 2011 (UTC)[reply]

Silver & Deming?

Silver & Deming redirects here, yet the term isn't mentioned in the text.

I think Silver & Deming refers to a straight shank, but I also think it means fractional sizes as opposed to letter or number sizes. As such, is it really a shank type? I'm hoping someone with more expertise can source a reference and make the edits. Or mention a source here and I'll wordsmith it in. Thanks! Myself248 (talk) 20:45, 8 July 2013 (UTC)[reply]

I already had coverage of S&D drills in this article, before some idiot wiped it out without my noticing. I just went and restored it. S&D bits have half-inch shanks and body diameters of 9/16" thru typically 1-1/2". I will take a photo of my S&D set if I can spend the time on it sometime soon. — ¾-10 23:33, 9 July 2013 (UTC)[reply]

SDS shank

I have a problem with this statement "The hammer of the drill acts to accelerate only the drill bit itself, and not the large mass of the chuck, which makes hammer drilling with an SDS shank drill bit much more productive than with other types of shank."

The mass of a chuck is insignificant when compared to a large (>20mm)SDS bit. Sure, not having to move the mass of a chuck helps, but the reason an SDS drill is "much more productive" is the optimised hammer action - it hits much harder per blow and has a lot fewer blows per minute, compared to a hammer-drill (accepting a straight shanked bit). — Preceding unsigned comment added by 105.227.19.92 (talk) 06:40, 17 September 2017 (UTC)[reply]

Your comments about the masses and drilling action make sense. Edit as you see fit.

I've seen bits offered with "SDS+ 4" shanks. Can someone explain what the "4" refers to? Thanks, ... PeterEasthope (talk) 14:46, 25 August 2020 (UTC)[reply]

Units attention

Is it really appropriate to metricate the non-SI units in this article? For instance, 1/2" is 12.7mm, but "metric" tools come in slightly different (and incompatible) sizes, e.g. 12.0mm, rather than being the same size with a different label. — Preceding unsigned comment added by StephenTX (talk • contribs) 19:38, 10 October 2016 (UTC)[reply]

Does Wikipedia articles accepts links to an external site, outside "See also" section?

I found external links in the "Threaded shank" item inside https://en.wikipedia.org/wiki/Drill_bit_shank

I don't know if its illegal or not. At least for me, I only saw external links in "See also"section. Gilson.soares (talk) 19:06, 30 December 2023 (UTC)[reply]

Straight shank variant

Currently not listed in the article... I have two long (10 yrs old?) hammer drill bits with a straight shank with three small tabs punched into one side. The 3/8" bit shaft is the same size as the shank, and the 1/2" bit narrows to the same 3/8" diameter at the shank. One bit shank comes to a dull conical point, rather than flat, so I imagine the hammer mechanism relies on the chuck moving with the bit because a pointy shank is likely not hit from behind. There is mention online of "Bosch exclusive PowerGrip round shank" that matches what I have here. Similar bits are still for sale at fastenal.ca, and they have varying shank thicknesses. I know nothing about the comparative advantages or obsolescence(?) of this shank style, and everything I see at the shops these days is SDS-plus.
