Our Review
This 19-piece cobalt and HSS bit set delivers solid performance for general metal drilling tasks. The titanium coating provides genuine heat resistance, extending bit life when drilling steel and cast iron at moderate speeds. The jobber length design fits standard drill chucks without fuss, and the twisted flutes clear chips efficiently on repeatwork. However, the mixed cobalt/HSS composition feels like a compromise—cobalt excels at speed, HSS at toughness, but this hybrid lacks the specialized edge of dedicated sets. For residential workshops or occasional contractor use, the impact resistance justifies the price point, though professional fabricators may prefer segregated bit kits. Expect decent longevity with standard power drills operating under 3000 RPM.
What We Like
- Titanium coating noticeably extends life when drilling repetitive holes in structural steel
- Impact-resistant design handles drill chatter without premature breakage
- 19-piece range (1/16" to 1/2") covers 95% of household and light commercial drilling needs
Watch Out For
- Mixed cobalt/HSS composition lacks the heat tolerance of pure cobalt sets when running high-speed applications
- No depth gauge markings or index case—bits scatter easily in workshop environments
The Verdict
“A reliable workhorse set for DIY and light trade use that punches above its price but won't match specialized cobalt kits for production drilling.”
