Keo 907-000-154 Combo Drill Countersink Size 5 Hss

Product Description

The KEO 907-000-154 is a combination drill and countersink tool machined from high-speed steel with a bright, uncoated finish. It is a size 5 tool featuring a 7/16-inch body diameter, a 3/16-inch drill point diameter, and an 82-degree included angle for countersinking operations. The 118-degree drill point angle and plain cutting edge style make this a reliable choice for metalworking and fabrication tasks. At 6 inches overall length, it qualifies as a long-length tool. Right-hand cut direction and a double end type extend usable tool life. Machinists and fabricators working in machine shops, maintenance environments, or light manufacturing typically install and use this tool.

This combo drill countersink is suited for countersinking operations in metal substrates where a clean, accurate seat for flat-head fasteners is required. The double-end configuration allows the tool to be flipped when one end wears, reducing tooling cost per job. It is not an aircraft-style tool and does not feature an insertable cutter head or taper, keeping setup straightforward for standard drill press or lathe applications.

Key Features

• High-speed steel construction for durability in metal cutting applications
• Bright, uncoated finish suitable for general-purpose countersinking
• Double-end design extends tool life by providing two usable cutting ends
• 82-degree included angle produces accurate countersink seats for standard flat-head fasteners
• 118-degree drill point angle for clean entry into metal workpieces
• Long-length body at 6 inches overall for added reach in deep or obstructed applications

Compatibility

Designed as a general-purpose OEM-style combo drill countersink for use in standard drill presses, lathes, and CNC setups that accept straight-shank tooling compatible with a 7/16-inch body diameter.

Installation Notes

This tool is installed and operated by machinists or skilled fabricators using a drill press, lathe, or CNC machine. Ensure the spindle is fully stopped and power is disconnected before changing or securing the tool in the chuck or collet. Use appropriate cutting fluid for the workpiece material to maintain tool life and finish quality. Verify spindle speed is appropriate for the material and tool diameter before beginning the cut.
