Subject: Zenith701801-List: Drill speed choice


Greetings listers,

I've been lurking for a number of years and am about to order the kit 
for a 750.  I'm trying to decide which drill to buy.  I have always 
heard that faster is better so I'm looking at a 6000 rpm drill. Is there 
a down side to turning the bit that fast?

Thanks in advance for any advice.

I should have done more research before I posted my question.

I found a nice page with some very useful info.  It answered my question 
in nothing flat.  Hope someone else will find it useful.

The answer to my question is that I can use the 6000 rpm up to a 1/4" 
bit diameter (which is the chuck size) without exceeding the recommend 
sf/m for 6061-t6.
