I believe they are both the same thing for the most part and do the same thing. From your link it appears the Dimpler bit is a trademark for that brand, where as I have always heard and used "dimpler" as a common term for that type of bit. I used one that looks exactly like Drywall Screw Setter in your link above and the packaging on mine calls it a Drywall Dimpler bit. The Dimpler Drywall Driver just appears to have more features such as the locking reverse and more "fancy" which most likely equals higher price. I did just fine with the other as the whole point is just to keep the screw from tearing through the paper and simply set to flush with the board with a slight "dimple" to mud over later. I think I paid $1.49 each for the ones I used. Personally, I have never even used this type of bit when working with cement or hardi board as those are usually strong enough that I can easily set the screws properly with little effort. You are going to be covering them with tile anyways so your mastic will easily cover any heads not flush as long as you at least get them reasonably close.
No announcement yet.
Do I need a drywall driver?
