Cobalt Drill Bit With Seven Eighths Inch Reduced Shank And Half Inch Shank, DWDCO Series, Built For Stainless Steel And Nickel Alloys, Gold Oxide Finish, Beast Mode Performance For Heavy Metal Cutting And Drilling
✔️ Single piece, dual shank options: 7/8 reduced and 1/2 shank
The cobalt alloyed drill bit cuts hard metals with ease, especially stainless steel and nickel alloys. This DWDCO series bit uses a gold oxide finish to reduce friction and heat, while a heavy-duty 135° split point ensures quick starts and accurate drilling. The round shank fits a wide range of toolholding systems and the bit is precision ground for concentricity between shank and body, delivering reliable performance.
✅ Cobalt alloy handles hard metals like stainless steel and nickel alloys
✅ Gold oxide finish reduces friction and heat during drilling
✅ 135° split point for fast, clean starts
✅ Round shank compatible with many toolholding systems
✅ Precision ground for tight shank-to-body concentricity
💡 What is a cobalt drill bit best used for in metalworking with tough materials like stainless steel and nickel alloys?
These bits are built to handle high-strength metals and frequent drilling without losing edge.
- High heat resistance helps maintain cutting edge - Ideal for stainless steel and nickel alloys - Gold oxide finish reduces friction and heat buildup - Compatible with common drill chucks and reduced shank options
