Utensile, 5/16" destro, carburo brasato

I bought these for a small lathe project cutting mild steel, and the C6 grade carbide held up way better than my old HSS bits. The brazed tip stayed sharp through several passes with no chipping, which was a pleasant surprise. For under ten bucks, this is exactly what a hobbyist like me needed.

Brazed carbide holds an edge noticeably longer than the HSS bits I’d been burning through, and the 5/16” right-hand geometry cuts cleanly on a few steel shafts I turned. Even on some scrap aluminum it didn’t chip, which was a pleasant surprise for a hobby lathe setup.

Used it on some mild steel and a bit of aluminum in the shop, and the C6 grade really holds an edge without chattering. The 5/16" size fits my holder perfectly, and it's nice that it works on non-ferrous too even though it's meant for steel.
