KEO General Purpose Three-Flute Countersinks.

Frequently Asked Questions

What is the KEO 100° countersink used for?

The KEO 100° countersink is designed for deburring and countersinking holes in metal, particularly for 100-degree flat-head screws. Its three-flute design provides smooth cutting and reduced chatter, making it suitable for general-purpose machining in automotive, aerospace, and fabrication industries.

What are the specifications of the KEO 917-000-871 countersink?

The KEO 917-000-871 is a 100°, three-flute countersink with a 1/4 in body diameter. It features an AlTiN coating on cobalt steel for heat resistance and extended tool life. This general-purpose tool is ideal for countersinking holes in steel, stainless steel, and non-ferrous materials.

Where to buy the KEO 917-000-871 countersink worldwide?

You can source the KEO 917-000-871 countersink through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to worldwide destinations. Contact us for availability and lead time; we supply KEO cutting tools to industrial buyers internationally.

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 hardness, and hole size. For hard metals, choose AlTiN-coated cobalt tools like the 917-000-871 for durability. Match the body diameter to your drill size and ensure the flute count suits your finish requirements.
