Frequently Asked Questions

What is the KEO 55081 countersink used for?

The KEO 55081 is a 110° six-flute countersink designed for creating smooth, burr-free chamfered holes in metal and plastic. Its high-speed steel construction and six-flute geometry reduce chatter and vibration, making it ideal for precision deburring and countersinking in machining, fabrication, and maintenance applications.

What are the specifications of the KEO 55081 countersink?

The KEO 55081 is a high-speed steel countersink with a 110° included angle, six flutes, a 3/16 in body diameter, and a 3/16 in shank. The six-flute design provides a smooth finish and reduces cutting forces. It is manufactured by KEO under part number 55081.

Where to buy the KEO 55081 countersink worldwide?

Contact us for availability and lead time; we source and deliver this precision tool to support your machining operations globally.

How to select the correct countersink for a 3/16 in hole?

For a 3/16 in hole, select a countersink with a body diameter matching the hole size, such as the KEO 55081 with a 3/16 in body. Ensure the shank fits your tool holder (also 3/16 in). The 110° angle is standard for flat-head screws. Six-flute designs like this KEO model reduce chatter for a smoother finish.
