“Solid budget-friendly starter set for home workshops, but inconsistent build quality limits reliability on demanding job sites.”
Our Review
This 19-piece cobalt and HSS set covers the basics for mixed-material drilling, with titanium coating providing decent wear resistance on ferrous metals and softwoods. The jobber-length bits fit standard 3/8-inch chucks, and the cobalt content improves heat tolerance compared to standard steel—useful when drilling stainless or cast iron repeatedly. However, the coating consistency varies across the set; some bits show uneven titanium coverage that affects edge retention. For occasional home shop use, this kit punches above its price point, but professional framers or metal fabricators will notice the bits dull faster under sustained impact drilling than premium alternatives like Dewalt or Irwin.
What We Like
- Cobalt blend handles stainless and cast iron better than standard HSS
- 19-piece range covers most common hole sizes from 1/16" to 1/2"
- Titanium coating reduces friction and extends lifespan on wood and light metals
Watch Out For
- Coating application inconsistent; some bits lack proper titanium coverage affecting durability
- Bit breakage risk is higher under heavy impact drilling compared to industrial-grade sets
The Verdict
“Solid budget-friendly starter set for home workshops, but inconsistent build quality limits reliability on demanding job sites.”
