Fastener reference

[Dick Linn]

Feel free to leave links to other good references, like tap drill charts, drill speed chart or what have you. This one isn't too bad, though a little simplistic when it comes to drilling different metals: http://www.ibiblio.org/twa/info/drillSpeedChart.pdf Or this one: http://members.home.nl/b.ollivier/ht...speedchart.htm

I have yet to find two charts that agree closely.

This is nice: http://www.hillmangroup.com/misc/Fas...0Chart%20A.pdf

Possibly useful: http://www.americanfastener.com/tech...ings_steel.asp

Lots of useful PDF reference docs here: http://catalog.starrett.com/catalog/...30801&Mode=REF

I find this one useful too: http://www.stanford.edu/~jwodin/holes.html

That is a nice one!

Here's a pretty good chart for SFM for various materials.

With SFM you can derive RPM [(4*SFM)/Tool Dia] for drilling/milling, as well as feedrates and other good info.
