9310 Material

Hi all, I am having a hard time drilling a .203 dia. hole 2" deep in these parts.   I had it going with a OSG coated drill, where it lasted about 9 parts (9 holes per part), but the material must be a little harder than before, and I can't get through 1 part without the drill needing change.  I am running a VF3 Haas, without TSC, anybody have any great suggestions on a drill, that they have had good results with?

Thanks,

Frank

The V-Series HELIOS® is the 1st drill to process deep holes 10X-20X diameter, without pecking and without the use of internal coolant supply. Flute form, point thining and compound lead construction are all patented technologies developed by OSG to make this drill do what no other parabolic HSS-Co drill can. The addition of our exclusive WXL coating technology makes non-peck drilling repeatable, even in the longest of production runs.

I'd keep it under 3in/min at that rpm. (or .001 chip load per tooth).

I'd also Peck given no TSC.

 i just did some 9310 drilled 3.5 deep with 7mm carbide coolant through. I still pecked be cause my coolant 'pressure' is very low. It wasn't hardened material, but got through 100 parts with that drill.
