Procurement Intelligence
The RS PRO HSS Countersink is a 25mm 90° three-flute cutting tool designed for creating conical depressions in drilled holes for countersunk fasteners. Installation involves securing in a drill chuck or countersink holder with appropriate spindle speed based on material. Critical verification: confirm the 90° angle matches your fastener head angle (typically #10-32 or M5 screws) before procurement.
