Frequently Asked Questions
What is a KEO 100° countersink used for?
A KEO 100° countersink with six flutes is used to create a smooth, chamfered recess for flat-head screws in metalworking and machining applications. The 100° angle matches common aerospace and industrial fastener standards, while the six-flute design reduces chatter for a finer finish.
