AC-Series

AC Countersinks for use with drills

SEVCAL AC Series Countersinks are designed as an economical means of combining drilling and coutersinking into a continuous operation. They can be positioned at any point along the fluted section of a drill and work best if adjusted to start countersinking when the drilling has been completed. The cutting teeth extend down into the drill flutes, and are arranged to give a shearing cut.

All SEVCAL countersinks are available in the following centerline angles:
