Frequently Asked Questions

What is the KEO 100° countersink used for?

The KEO 100° countersink is used to create a conical recess in metal or plastic for flat-head screws or rivets. Its single-flute design provides fast, chatter-free cutting in production environments. Common applications include aerospace, automotive, and general machining where precise countersinking is required.

What are the specifications of the KEO 100° countersink?

This KEO countersink has a 100° included angle, one flute, and a 1 1/4 in body diameter. It is made from high-speed steel (HSS) for durability. The manufacturer part number is 919-000-137. It is designed for fast cutting in ferrous and non-ferrous materials.

Where to buy the KEO 100° countersink worldwide?

You can source the KEO 100° 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 on this single-flute countersink.

How to select the correct KEO countersink for my application?

Select the KEO countersink based on the screw head angle (100° for flat-head screws), material type (HSS for general use), and body diameter matching the screw head size. For production runs, the single-flute design offers faster chip evacuation. Always match the countersink angle to the fastener angle for proper seating.
