Sebastian F. ★★★★★

The 5% cobalt in the M35 steel really makes these bars hold up longer than standard HSS sets. I've already used the 9/16" bar to bore several deep holes and it's still cutting cleanly.

Jacob ★★★★★

The 1/2" shank fits my drill chuck perfectly, and the M35 cobalt steel really holds an edge on mild steel. I've bored through over a dozen 1/8" plates so far without needing to sharpen.

Carter ★★★★★

I was pleasantly surprised by the chip clearance on the smallest 5/16" bar; it cut cleanly without binding. For the price, having three different bore sizes in one set makes a lot of sense for general machine work.
