Choose the right countersink angle, body diameter, and number of flutes for your application.
Drill-Point Countersinks for Screws
Save time by drilling a pilot hole and countersinking in a single step. These countersinks have a small drill point to drill new pilot holes topped with cone-shaped recesses for screw heads.
High-Speed Steel
 |
2 Flutes |
These versatile, wear-resistant countersinks cut cleanly in most materials, including plastic, aluminum, and steel.
Number of Flutes—Countersinks with fewer flutes reduce chatter, so you can run them at high speeds. Countersinks with a higher number of flutes remove more material per revolution, leaving a smoother finish and extending tool life.
