Look at the size compared with as standard 3.2mm tungsten!!
Our Customer required very long (250mm) tungsten for a semi-automated hard access application. in this application the customer had to use an XXL long ceramic due to the access on the job and its associated jigs. When using the standard length tungstens, they could only regrind a few times before they couldn’t grip the tungsten in the collet anymore.
