Madison F. ★★★★★

The carbide tips cut cleanly through steel on my mini lathe, and the variety of bar lengths saves me from swapping tools constantly. For the price, having three different minimum bore sizes in one set is a solid deal.

Zoe ★★★★★

The 9/16" bar with the 3" depth range handled a slightly overbore pocket without chattering, which surprised me for the price. Tips are sharp right out of the box and the holder fits my mini lathe’s tool post snugly.

Ella ★★★★★

The carbide tips on these bars cut through mild steel like butter on my mini lathe, and the 5/16" minimum bore size let me reach into a tiny brass fitting I’d been avoiding. The heat-treated shanks hold up well under pressure, no flex even at the 3" depth.
