Keo 906-000-202 Combo Drill Countersink 1/8 in Hss

Product Description

The KEO 906-000-202 is a combination drill and countersink designed for simultaneous center drilling and countersinking in a single operation. Built from high-speed steel with a bright, uncoated finish, this tool handles both drilling and chamfering without a tool change. The body diameter measures 1/8 inch, the drill point diameter is 3/64 inch, and the overall length is 1-1/4 inches. The 118-degree drill point angle and 60-degree included angle make it suitable for standard center hole and countersink work on metal and similar materials. It cuts in the right-hand direction and features a bell-style cutting edge for clean, consistent countersunk seats.

This combo drill countersink is suited for machine shop, toolroom, and light fabrication environments where precise center holes and countersinks are required in a single pass. The double end type and bell cutting edge style are appropriate for producing countersunk holes that accept flat-head fasteners or provide center support for lathe work. Machinists, toolmakers, and CNC operators commonly use this tool in drilling and milling operations on steel, aluminum, and similar workpiece materials.
