Drywall screws, needle point vs drill point

[threesixright]

Hi All,

Could someone explain when you should use the one or the other?

Thanks!

// UPDATE
The question is not about fine = metal and coarse is wood.

I do understand they are both for metal-studs. Its more when to use the drill-point. I was thinking maybe they (drill point) screws slightly easier when screwing though drywall and behind are two (overlapping) pieces of metal stud (like where the horizontal and vertical pieces meet)?

I use the drill point when I'm attaching drywall to the metal stud.  I use needle point for everything else.

You'll also notice that the drill point has finer threads for metal studs.

Fine thread = metal studs
Coarse thread = wood studs

Some prefer the drill tip on fine thread screws for metal studs.

Kind regards,
Oliver

Oopsie [big grin], should have mentioned that that much was clear (fine = metal) [embarassed]

But once again thrown off since SPAX has 2 types of fine threads for metal studs. So, they are both fine threads, only one has drill point and both are for drywall.

The pictures are of the GIX-A and GIX-D.

Another type I have seen would be 'rock-to-rock' screws used
when laminating drywall.

They have a deep, coarse thread.

Needle point or self piercing for lighter gauge (25-20) steel stud. Self drilling for heavier gauge (20-14) steel stud.

Thanks! This I was looking for.

Needle points are specifically designed for lightweight Furring Channel, but will work OK in softwood scantling also.

As previously stated, drill points are specifically for structural steel scantling.
