Keo 907-000-071 Combo Drill Countersink Size 2 3/16 in

Product Description

The KEO 907-000-071 is a combination drill and countersink tool designed to drill a pilot hole and form a countersink in a single operation. Built from high-speed steel with a bright uncoated finish, it delivers reliable cutting performance across a range of metalworking and fabrication tasks. The tool features a 3/16-inch body diameter, a 5/64-inch drill point diameter, and a 90-degree included angle for the countersink profile. With a 118-degree drill point angle and right-hand cut direction, it suits standard drilling practice on drill presses and CNC setups alike.

This combo drill countersink is suited for machine shops, maintenance facilities, and fabrication environments where countersinking fastener seats in metal workpieces is a routine task. The plain cutting edge style and non-tapered, non-aircraft body make it a straightforward general-purpose tool. Its long-length designation and 4-inch overall length give it reach for deeper setups or fixtures that require extended tool clearance. Licensed machinists, tool-and-die technicians, and maintenance mechanics commonly select this style of tool for production and repair work.

Compatibility

Designed as a general-purpose combination drill and countersink for use in standard drill press, lathe, or CNC machining center setups requiring a size 2, 3/16-inch body diameter tool with a 90-degree countersink profile.

Installation Notes

This tool is installed in a compatible drill chuck or collet sized for a 3/16-inch shank. Secure the workpiece firmly before operation and confirm spindle speed is appropriate for the workpiece material and tool diameter. Inspect the cutting edges for wear or damage before use and replace the tool if chipping is observed. Follow applicable shop safety standards and machine guarding requirements during operation.
