5-Piece M35 Cobalt Drill Bit Set for Stainless Steel Alloys
✔️ Sizes 9/16 to 1 in with 1/2 in reduced shanks in cobalt

This cobalt drill bit set is built for heavy metal work, ideal for stainless steel and nickel alloys, and is commonly used in metal fabrication and automotive applications with portable drills. It features a gold oxide finish, which is thinner than black oxide and used to identify cobalt steel while maintaining performance similar to uncoated tools.

✅ Sizes included: 9/16", 5/8", 3/4", 7/8", 1" with 1/2" reduced shanks
✅ Cobalt steel construction provides heat resistance for hard metals
✅ 135° heavy-duty split point for fast starts and reduced walking
✅ Precision ground for high concentricity between shank and body diameter
✅ Common flute and overall length for minimal tool changes

💡 What is a cobalt drill bit set commonly used for in metalworking?

They’re handy for drilling tough metals where standard HSS bits wear fast, delivering longer life and cleaner starts.
