festool impact driver

[James Watriss]

So... The question remains:

When will NA see what we lovingly term an impact driver?

Or should I waste money on new batteries for my Makita ?

 

[Ken Nagrod]

My advice will be limited to saying, if you like the Makita style of impact driver, get the batteries.

I think it's all very simple

Female fittings used for impact wrench
Male fittings used for impact driver

SDS Drills (great!!)
Non SDS drills (rubbish)

that's all the categories you need!

to further the debate what does SDS actually stand for?

I'm starting with "Schnell Drilling System"

Get googling for a definitive answer

The correct answer is:

SDS (or Slotted Drive System) bits for hammer drills/rotary hammers allow the bit to slide in the chuck and enhance the hammering action of the tool. For most applications, these bits provide plenty of torque.

SDS Max bits are similar to SDS bits, but have larger shanks and come in larger sizes than SDS bits. These powerful bits are useful in industrial applications.

Also SDS drills can be used in Hammer ONLY mode which is very useful for breaking up bricks/concrete.

Hope this helpful to you.

There are also rotary hammers (US terminology) that use a "Spline" shank, similar to SDS in purpose though they attach somewhat differently.

I get the impression they fall somewhere in between SDS/SDS+ and SDS Max in terms of the bit sizes.  Older standard; most of the newer stuff seems to be either SDS or SDS Max.
