Frequently Asked Questions

What is the KEO 100° 6-flute countersink used for?

The KEO 100° 6-flute countersink is used for deburring and countersinking holes in metal, plastic, and wood. Its six-flute design provides a smooth finish and reduces chatter, making it ideal for precision work in machining and fabrication. It is commonly used in automotive, aerospace, and general manufacturing applications.

What are the specifications of the KEO 919-000-424 countersink?

The KEO 919-000-424 is a 100° countersink with six flutes and a 5/8 in body diameter. It is made from high-speed steel (HSS) for durability and sharpness. The 100° angle is suited for flat-head screws and rivets. This tool is designed for smooth-finish countersinking in various materials.

Where to buy the KEO 919-000-424 countersink worldwide?

You can source the KEO 919-000-424 countersink through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to worldwide destinations.

How to select the right KEO countersink for your application?

Select a KEO countersink based on the screw head angle (e.g., 100° for flat-head screws), material type (HSS for general use), and body diameter matching the hole size. For smooth finishes, choose a six-flute design. Always match the countersink angle to your fastener's head angle to ensure proper seating and flush results.
