Threading Tool, Internal, 3/8 Indexable

Needed something to cut internal threads on a 0.47" minimum bore and this little holder handled it fine right out of the box. The insert sits solid with no chatter, and the 4" overall length gives me enough reach without flexing. Only ran a handful of threads so far but the finish looks clean.

The 3/8" shank fits my little Atlas 618 perfectly and the 4" overall length gives me plenty of reach on deeper bores. Cuts clean right hand internal threads in aluminum without any chatter. Nice to finally have an indexable option this small.

I was worried the minimum bore of 0.47" would be too tight for the small hydraulic fittings I thread, but it cleared fine and the 4" overall length gives me plenty of reach. Cuts clean right hand internal threads in aluminum with no chatter.
