Drilling Mild Steel... Anyone have online sources for such a chart? I have one on my site, but someone actually convinced my customer he needs a tremendous amount of HP for a simple hole. He asked for outside sources of info backing up my quote so... I need a chart from someone else.
Any help would be greatly appreciated.

Machinery's Handbook has formulas, in the section titled "Machining Power," that will allow you to build a new table (in Excel?), or to verify the figures in your current table.

Ned,
My thoughts exactly... And much appreciated tip... But he is not a technical-type and it's all "Greek" to him... He is looking for something similar to this online or in print that I can fax him:

Hey Joe,
Do you provide custom multiple spindle drill heads? I have a need for one that will drill 6 holes at once and was considering a Sugino, but I will take a look at other bids.
If you're interested, let me know and we can talk over the details.

To find the Required Horsepower (HPc), please enter the Depth of Cut (D), the Width of Cut in inches(W), the Inches Per Minute (IPM), and the K constant (See Below )
. HPc=(D x W x IPM) / K
HPc= D= W= IPM= K=
Material K Aluminum 4.0 plus Brass soft 3.0 Brass hard 2.0 Bronze hard 1.4 Bronze very hard .65
Cast iron (up to 200 BHN) 1.50
Cast iron (over 200 BHN) 1.00
Malleable iron 1.25 Steel (100 BHN) .80 Steel (150 BHN) .70 Steel (200 BHN) .65 Steel (250 BHN) .60 Steel (300 BHN) .55 Steel (400 BHN) .50
I'd be glad to quote it...
Give me a call and/or check out the multi-drill site URL below. Mention the newsgroup so I know who I'm talking to when you call. Just ask for Joe, Jr.
