Crazy Drills - Anyone using them???

[Newbeeee™]

Had an application for some deep drilling - looked at these and can't help being impressed.

But delivery was over a week and we all know what the subby game is like

 

Anyway, anyone ever used one?

Crazy. I used them in 17-4PH 20x diameter.

 

.093 diameter 1.8 deep @ 6100rpm and .003ipr (18 ipm). You have to use the pilot drill first and follow the correct sequence of events (pilot drill 2xD, start spindle @ 500rpm, feed into hole, increase RPM, drill with no peck,......etc...)

 

I was extremely impressed with tool life and performance. I had to hold true position of .003 and this drill did it without any problem. They are a bit pricey but well worth the cost.

I like the name, but also looks like quality tool.
