6 Flute Countersinks, also called chatterless countersinks, are designed to provide more metal removal than countersinks with less flutes. They are also more effective on harder materials and provide a cleaner, more chatter free cut.
Great for enlarging tang holes and countersinking holes in handle material for recessed flat head screws.
