60-degree 3-flute HSS countersink
The Cleveland C46189 is a high-speed steel countersink with a 60-degree angle and three flutes. It produces clean chamfers and deburrs holes in steel, aluminium and plastics. The black oxide finish resists corrosion and reduces friction during use. This tool fits standard drill chucks and suits workshop and maintenance tasks.
Replaces worn or single-flute countersinks
Swapping a dull or single-flute bit for this three-flute design gives smoother cutting and less chatter on harder materials. The upgrade is worthwhile when existing countersinks leave rough edges or require excessive pressure. It is not suited for high-volume CNC production runs or for cutting angles other than 60 degrees.
