Customer Reviews (4.6 / 5 · 5 reviews)

John O. ★★★★★

The 1/2" bar fits my tool post perfectly and the inserts lock in securely with no wiggle. These bars cut through steel like butter with a nice surface finish.

Charlotte F. ★★★★★

The 3/8" bar at 6 inches long gives just the right reach for my lathe's deeper bores without excessive flex. These indexable inserts cut clean and hold an edge well through aluminum and mild steel.

Timothy ★★★★★

The S05H-SCLCR2 designation is spot on for my lathe, and the 5/16" bar at 4" long fits perfectly in tight spots without flexing. These cut clean on aluminum and steel with those CCGT inserts, and I've already burned through a few setups with zero chatter issues.
