How to select the correct threaded-shank countersink for a job?
Select a countersink with the same angle as your fastener head—82° for standard flat-head screws. Match the shank thread size (here 1/4"-28) to your holder or machine spindle. Choose carbide for hard materials like stainless steel or composites; three-flute designs reduce chatter and improve finish.
