Countersinks

Our single flute countersinks are used to provide a heavy chamfer in the entrance to a drilled hole. They are often used to allow the correct seating for a countersunk-head screw or to provide the lead in for a secondary machining operations such as tapping. 

• Our countersinks are manufactured with 60°, 82°, and 90° angles. 
  
• Countersunk-head screws that follow the Unified Thread Standard very often have an 82° angle.
  
• Countersunk-head screws that follow the ISO standard very often have a 90° angle.
