Mia K. ★★★★★

Finally, a groover insert that actually holds up to stainless without chipping—the 1/32" width cuts clean on my Warner tool, and it’s sharp enough for light passes.

Evelyn ★★★★★

The T-15 steel is holding an edge beautifully after a full day of grooving brass, and the 1/32" width is cutting exactly to spec. It seats snugly in the holder without any wobble, and I'm already ordering a spare.

Jacob ★★★★★

Finally got the T-15 steel insert dialed in and it cuts those 1/32" grooves cleanly without chattering, even on some harder steel. Takes a bit of patience to set the depth right, but once you're there it holds the edge well.
