Talk:пёрка

An interesting word. I didn't even know that it existed :). As far as I understand, пёрка is an obsolete term (and now a colloquial synonym) for перьевое сверло, which should be translated as spade bit.

I notice a drawing of a couple of types of пёрка [1]. —Stephen 18:44, 9 August 2007 (UTC)

I see. A type of drill bit called центровая пёрка on that picture is exactly перьевое сверло (spade bit). A type of bit which is called ложечная пёрка is now more formally referred to as ложечное сверло (I don't know an English term for that one. A flat bit, or spoon bit, perhaps?).

I think ложечное сверло is an called an auger bit. However, spoon bit might be a better term. One is shown at https://www.fine-tools.com/G303710.htm —Stephen 20:16, 9 August 2007 (UTC)

According to w:Drill_bit#Auger_bit, auger is different from spoon bit. On that Russian picture its counterpart was called витое сверло (also a dated term, although I don't know a modern one). Dart evader 20:26, 9 August 2007 (UTC)

I think the different names are not very definitive. Different people and companies call the same bit by different names. Some use flat bit in place of spade bit, for example. To me, винтовое сверло sounds like витое сверло. The page at http://multitran.ru/c/m.exe?t=2875772_1_2 shows how the same name will be translated in different ways for different industries. —Stephen 20:46, 9 August 2007 (UTC)

OK. Returning to the matter at hand, I think that the first (broadest and safest) definition for пёрка should be сверло по дереву (wood drill or wood bit). And the more precise senses would be flat bit, spade bit, spoon bit etc. Dart evader 21:14, 9 August 2007 (UTC)
