Customer Reviews (5.0 / 5 · 5 reviews)

Eli ★★★★★

Ground the insert with the screw is nice and snug, no wobble at all when I cut. These holders are showing cleaner finishes on my steel parts than my old cheap bars did.

Brian ★★★★★

I've been using these for a few weeks now, and the carbide inserts hold an edge noticeably longer than my old HSS bits. The 3/8" boring bar in particular has been excellent for cleaning up some tight internal diameters on my lathe.

Hannah ★★★★★

These holders locked into my tool post with zero play, and the 3/8" boring bar made a smooth, chatter-free hole in 4140 steel. I was pleasantly surprised the inserts came pre-indexed and ready to cut right out of the box.
