Keo 78005 Hss Combo Drill Countersink Set 60 Deg 5 Pc

Product Description

The KEO 78005 is a 5-piece combination drill and countersink set manufactured from high-speed steel, designed for creating centered starting holes and countersunk profiles in a single operation. The set covers trade sizes 1 through 5, giving machinists and fabricators a range of diameters without tool changes. The 60-degree included angle is the standard geometry for most center-drilling and countersinking applications on metal workpieces. Right-hand cutting direction suits conventional machining setups, and the plain cutting edge style provides straightforward chip clearance on the materials this tooling is built for.

This set is suited for metalworking shops, maintenance and repair operations, and production environments where center drilling and countersinking are routine tasks. Long-length geometry extends reach for deeper setups or fixtures where clearance is limited. The 5-piece assortment allows technicians to match the correct tool size to the fastener or center-drill requirement at hand, reducing the need for individual tool sourcing across common size ranges.

Key Features

• 5-piece set covering trade sizes 1 through 5 for versatile coverage across common applications
• High-speed steel construction for durability in metal drilling and countersinking operations
• 60-degree included angle, the standard geometry for center drilling and countersinking
• Right-hand cutting direction compatible with standard drill press and lathe setups
• Plain cutting edge style for straightforward chip evacuation
• Long-length design for extended reach in restricted-clearance setups

Compatibility

Designed as a standard combination drill and countersink set suitable for use in drill presses, lathes, and milling machines where right-hand cutting tooling is required.

Installation Notes

These tools are installed in a standard drill chuck or collet on a lathe, drill press, or milling machine. Secure the shank firmly before operation and confirm spindle direction is set to right-hand rotation. Use appropriate cutting fluid or coolant for the workpiece material to extend tool life. Inspect each tool for wear or chipping before use and replace any damaged piece before running.
