HSS-E05 Piloted Counter Bores 180°

Description

✅ Counter bores with fixed pilot
✅ For cheese, fillister screw caps
✅ For through holes (Fine, Medium)
✅ Tapping holes (K)
✅ Chamfering angle 180°
✅ Bright finish

The HSS E05 flat counterbore with a 180-degree countersink angle is suitable for precisely countersinking screw heads. The guide pin ensures precise guidance in the hole and prevents the tool from wandering.

You can use the flat countersink to cleanly countersink both hexagon socket and cylinder head screws. Its design makes it suitable for through holes (F fine, M medium) as well as threaded core holes (K). The ground surface reduces friction and supports uniform machining.

Areas of application for the flat countersink
Metalworking: countersinking hexagon socket and cylinder screws
Mechanical engineering: precise adjustment of screw connections in components
Workshops: universal tool for through holes and threaded core holes
