Dracon AT 8762 Impact Tool and blades

The discussion of the 714B tool reminded me of this tool. 

Any idea of the purpose for the 9224 blade (on right)?

The 9224 kind of looks loosely like a Krone-type IDC tool's tip, with automatic scissors that trim the excess wire when the tool clicks on insertion...

The picture below is of the tip of my BT-branded Krone tool with your picture in the background, it's vaguely similar, but without a better angle on the 9224 tip I couldn't say if the 9224 is meant to work like the Krone design or not...

Krone had a different idea for IDC terminals, instead of them being at a 90 degree angle to the cable, they turned the blade in the terminal round by 45 degrees so the blade cut into the insulation at an angle, which apparently provides a better connection with less chance of service degradation due to expansion & contraction of the metals causing a loose joint in the IDC slot, and of course, they had to design their own style tool to accommodate this difference...

Just adding a PDF from ADC-Krone which depicts the difference between their LSA-Plus and 110 IDC terminals...

Worth a read, or just good for looking at the nice pictures...

Thanks for the photos and catalog.

Here's more detail on the 9224...

Yeah, looking at it like that, I think it has been designed to use with Krone type IDC hardware, or at least something very similar...
