Key item features

  • 【High-Speed M2 Steel Material】This 5‑piece countersink drill bit set is constructed with M2 high‑speed steel for the drill bits and high carbon steel for the countersink parts, delivering exceptional hardness, sharpness, cutting power, and long‑lasting durability for heavy‑duty drilling and countersinking tasks. The premium materials ensure stable performance, wear resistance, and extended service life even with frequent use on various hard materials.
  • 【Adjustable Depth Precision Control】Each countersink drill bit features adjustable length settings with a included hex wrench, allowing users to precisely set and control drilling depth for consistent, uniform, and professional countersink holes every time. The flexible depth adjustment ensures accurate screw hole finishing, matching different material thicknesses and project requirements for clean, flawless results.
  • 【82-Degree Chamfer Angle Design】With a standard 82‑degree chamfer angle and three sharp cutting edges, these countersink bits provide efficient, smooth cutting action that creates perfectly angled, clean screw countersinks for flat, polished surface finishes. The optimized cutting design ensures fast chip removal, reduces heat buildup, and prevents material burning during drilling for professional quality woodworking and metalworking.

Bits don't seem to cut very well, but serve their purpose. Can be replaced, the recessed cutter is really what I was after.
