Description

Flute Length – The length of the flute determines the thickness of the metal that self-drilling screw can be used on. The flute is designed to extract the drilled material from the hole.

If the flute becomes blocked cutting will stop. Simply put if you have are attaching thick pieces of material together then you will require a self-drilling screw with a flute to match. If the flute becomes blocked and you take no action the drill point will likely overheat and fail.
