Also reduced to $275 is the DeWALT x McLaren 18V XR Brushless Impact Driver Kit 2 x 5.0Ah.

Considering the 5Ah batteries alone are about $130 each and the Tstak box is $69, it's a pretty decent deal.
Neither kit was showing for me on either stock checkers at time of posting.
Hammer drill kit I/N: 0706023
Impact driver kit I/N: 0706022
Also note that the redemption offer showing on the impact driver page is for a $1500 spend.
Both kits are currently $319 at Sydney Tools & TKD, and $349 at Total Tools, so you could try a price match if you prefer to buy from one of them.
If the above links are being flaky try this, https://www.bunnings.com.au/search/products?page=1&q=dewalt+…
Can this be used as a normal drill aswell or is the 'hammer' function not able to be disabled?
