Frequently Asked Questions

What is the KEO 55090-TIN countersink used for?

The KEO 55090-TIN countersink is used for deburring and countersinking holes in metal, plastic, and wood. Its 110° angle and six-flute design produce a smooth finish, making it ideal for aerospace, automotive, and general machining applications where precision and surface quality are critical.

What are the specifications of the KEO 55090-TIN countersink?

The KEO 55090-TIN countersink has a 110° included angle, six flutes, a 7/8 in body diameter, and is made from TiN-coated high-speed steel. The TiN coating reduces friction and extends tool life. It is designed for smooth-finish countersinking in various materials.

Where to buy the KEO 55090-TIN countersink worldwide?

You can source the KEO 55090-TIN 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 this tool to procurement teams and engineers globally.

How to select the correct KEO countersink for your application?

Select a KEO countersink based on the required angle (e.g., 110° for standard flat-head screws), flute count (six flutes for smoother finish), body diameter matching the hole size, and coating (TiN for longer life in abrasive materials). Always match the tool to your material and desired surface finish.
