Jason ★★★★★ Oct 21, 2026

The 7/8"-20 thread on this shank matched perfectly with my existing boring head setup, and the 3MT taper seated firmly with no wobble. The alloy steel feels dense and well-machined, giving me confidence it'll handle tougher cuts.

Edward ★★★★★ Oct 20, 2026

The nickel coating is holding up perfectly on my lathe, even after several hours of heavy use. Threads onto the 7/8"-20 arbor smooth as butter, no wobble at all.

William W. ★★★★★ Oct 19, 2026

The 20CrMnTi alloy steel feels incredibly solid, and the nickel coating looks like it’ll hold up well in my shop. Threaded onto my drill chuck without any wobble, and it cut through a tough hardwood like butter.
