The 1-3/8" clamping diameter fits my end mill holder perfectly, and the 6-1/2" reach gives me plenty of positioning flexibility for tricky setups. I've already used it on three different jobs with zero slippage.

Finally a holder that actually fits my end mill securely without wobbling. The 1-3/8" clamp diameter is spot on for standard tooling, and that full 6-1/2" adjustment range makes setup so much easier than my old rig.

The 6-1/2" reach gives me plenty of room to position the indicator on my mill without crowding the workpiece. Clamping onto the end mill holder is solid and locks down tight, and it's held up fine after a few weeks of daily use.
