Driil Recomendation

[#Rekd™]

Hi.

 

I need a recommendation for a 9/16 drill bit. I have to do a couple of lathe jobs that require this drill, some Aluminum and some Brass. I need to drill about 3" deep with coolant through. I would prefer an indexable.

 

Thank you in advance!

we have good luck with the "iscar sumocham" drills in 6al-4v going 2.0+ deep in 1 shot with high press coolant.

they have drills in the range you need.

The Seco Crown-Loc is a good drill, we use these on our lathes.

we use these type drills from sumitomo with great results using TSC on our vertical machining centers. http://www.sumicarbide.com/prodline_drilling.htm

Check out OSG Exocarb brand drills, we have one running a production job that has drilled a 1/2" hole 2.8 deep in over 2200pcs. Have never looked back since. This is drilling in cast aluminum and various 6061 parts with thru coolant, shows hardly any edge wear. I figure its good for atleast another 2-3 thousand parts, now that drill is paying for itself 10x over.
