Keo 906-000-036 Combo Drill Countersink 1/8 in Hss Tin

Product Description

The KEO 906-000-036 is a combination drill and countersink designed for simultaneous drilling and countersinking operations in a single pass. Built from high-speed steel (HSS) with a titanium nitride (TiN) coating, it delivers extended tool life and reduced friction compared to uncoated HSS. The body diameter measures 1/8 inch, with a drill point diameter of 1/32 inch and an overall length (OAL) of 1-1/4 inches. The 118-degree drill point angle and 60-degree included angle make it suited for preparing fastener seats and center holes in metalworking and fabrication environments. Right-hand cutting direction is standard.

This combo drill countersink is intended for metalworking, machining, and fabrication applications where countersunk fastener holes are required. The aircraft style and double-end type make it appropriate for precision work in sheet metal and general machining setups. It is sized as a Trade Size 0 tool, which corresponds to smaller diameter hole prep work. Machinists, tool and die technicians, and fabricators working with drill presses, CNC machines, or lathes will find this tool suitable for center drilling and countersinking in one operation.

Key Features

Compatibility

Designed as a standard Trade Size 0 combination drill countersink suitable for use in drill presses, CNC machining centers, and lathes that accept 1/8 inch shank tooling.

Installation Notes

Installation and use should be performed by qualified machinists or fabricators familiar with rotary cutting tools. Ensure the machine spindle is fully stopped and power is locked out before securing or changing the tool. Use appropriate work-holding and operate at feed rates and speeds appropriate for the workpiece material and tool diameter. Do not exceed the tool's rated cutting geometry by forcing the countersink into oversized holes.
