High-Speed Steel Drill-Point Countersinks for Screws

A small drill point at the tip lets you use the same tool for drilling and countersinking holes. An 82° countersink angle is compatible with the profile of flat- and oval-head inch screws; a 90° countersink angle is compatible with the profile of flat- and oval-head metric screws and is also good for deburring.
