  • Longer-Lasting AlTiN Coating: Premium AlTiN coating delivers extreme hardness, heat resistance, and low friction—ensuring long-lasting durability for countersink drill bit set and precise metal finishing.
  • Optimized for Hard Metals: Engineered for stainless steel, alloy steel, and other hard metals. Designed specifically for hard materials, it may not deliver the same surface finish on softer metals.
  • 5-Flute Design for Smooth Cuts: Five-flute geometry reduces vibration, distributes cutting forces evenly, and ensures stable, smooth cuts with minimal burrs—perfect for counter sink bit for hard metal.
  • Countersinking & Deburring: Ideal for chamfering hole edges, deburring, and creating flat countersunk seats on pre-drilled holes. Works seamlessly with countersink drill bit set.
  • Universal Quick-Change Hex Shank: 1/4" hex shank fits drills and electric screwdrivers securely. Quick-change design saves time and ensures easy, precise use with countersink drill bit. Comes with a durable storage case for organized storage and jobsite convenience.
