Sofia C. ★★★★★

The 0.50" minimum bore size is exactly what I needed for my smaller workpieces, and the CCMT inserts lock in solidly. Cuts clean without chatter on mild steel.

Steven ★★★★★

I've been using this 3/8" indexable boring bar for a few weeks now, and the CCMT inserts hold an edge really well even on some tougher steel. The minimum bore diameter of 0.50" is spot on for my small jobs, and the setup is straightforward.

Brian ★★★★☆

I was a little worried about the insert seating, but it locks in solidly with no wiggle. Makes clean, repeatable cuts on my small lathe projects.
