How are drill bushings generally used? — Preceding unsigned comment added by 2602:306:8080:34A0:6954:2D67:F378:5F1C (talk) 20:01, 13 September 2015 (UTC)[reply]

Limited coverage

[edit]

The information given on customary bushings used in the USA is detailed. However, it is almost certain that engineers in other countries also use drill bushings, and this article gives little or no information about them and their applicable standards. It needs to cover the types and standards used in all other industrialised nations, at least those using English as a national language or lingua franca.

Here are a few questions I'd imagine an engineering or industrial design student asking about drill bushings:

  1. What do Europeans use? Is there a DIN standard for bushings?
  2. British and British Commonwealth; Indians, Australians, Canadians?
  3. Mexicans, Brazilians?
  4. Russians and Russian Commonwealth?
  5. Chinese, Japanese and Koreans? Is there a JIS standard for bushings?
  6. Are the US types and standards used elsewhere?
  7. How would one convert a US specification to the nearest metric European equivalent?

(added to head section) (is that correct? forgive me, i am new here)

In most Western European countries bushing are standardized via several standards with DIN 172A and ISO 4247 being most prevalent.

In the United Kingdom, and some former colonies, especially India, Drill Bushings are referred to as, "Drill Bushes." <!i have not found any good source for this beyond my presonal knowledge (and a Google searches..)-->colin (talk) 00:48, 12 November 2019 (UTC)[reply]

/*New Subheading "Gun Drill Bushings"/ For use in a Gun drill these bushings are similar to a Renewable bushing but reversed in that they support the drill at the "head" end of the bushing which is brought into contact with the workpiece. Gun Drill Bushings generally are determined by the manufacturer of the Gun Drill equipment with each having their own standard design.

/*New Subheading "Air-Feed Drill Bushings"/ Air-Feed Drills (also known as Self-Feed Drills) are typically used in aerospace manufacturing and require a unique bushing. Like Gun Drill Bushings each manufacturer of Air Feed Drills have a specific standard. Unique to Air-Feed Bushings is the design in which the bushing screws onto the drill and also has a helix or flanged shaped section to allow the user to mount the drill to the jig. The bushing, generally, consists of two parts the screw on collar and a pressed in "nose." the nose provides the drill bearing function.[1]
