I'd like to offer my reasoning on why *I* purchased a D-handle model.
But first, one reason to absolutely NOT to buy a D-handle - that's if the extra height of the handle/tool is a problem for you, i.e. won't fit where you need it to go. I might be stating the obvious, but it might be overlooked?
Now, reasons TO buy the D-handle:
• More versatile. In addition to using it as a D-handle, you can still use it with a barrel handle grip. It has the same two switches on the body that the barrel-handle version has, but ADDS a third switch - with speed control!!! - on the D-handle.
• Easier on small(er) hands. My wife can't comfortably hold the barrel version. The D-handle is MUCH smaller and easier to control. PLUS, the barrel on the D-handle SEEMS smaller than the barrel on the other version but it's probably the same? I didn't measure.
• Trigger speed control - this was the big one for me. I may be an 'old-fogey' but I like the option of controlling the speed myself with the trigger. For instance, slowing down where I exit a cut. You can't do that on the barrel-grip model. And you STILL have the 'A' (auto) setting available to you as well, just as you do on the barrel-grip.
All of these are what I call 'checkmark' items. I.e. either saw will perform the main functions that it is built to do. The checkmark items may have value to you, or they may not.
And THAT, boys and girls, is why Festool makes two models!
