Frequently Asked Questions

What is a KEO 120° countersink used for?

A KEO 120° countersink with three flutes is used to create a conical recess for flat-head screws or to deburr holes in metal, plastic, or wood. The 120° angle is common for aerospace and sheet-metal work, ensuring flush fastener seating.

What are the specifications of the KEO 917-000-053 countersink?

The KEO 917-000-053 is a general-purpose three-flute countersink with a 120° included angle and a 3/8 in body diameter. It is made from high-speed steel (HSS) for durability in ferrous and non-ferrous materials. The three-flute design reduces chatter for a smoother finish.

Where to buy KEO countersinks worldwide?

How to select the right KEO countersink for your application?

Select a KEO countersink based on the screw head angle (e.g., 120° for aerospace), material (HSS for general use), and flute count (three-flute for reduced chatter). Match the body diameter to the hole size. For deburring, a 120° angle works on most metals.
