Over in the UK, Dewalt has announced two new 20V Max brushless rotary hammer kits, models DCH273P2 and DCH274P2, which will ship with 5.0Ah battery packs.
The new rotary hammers will be given 18V XR branding overseas, and 20V Max branding if/when they are released in the USA.
Dewalt says that, compared to the DCH253 rotary hammer that came out in 2013, the new rotary hammers will drill 63% more holes. They can drill more than 90 10mm x 80mm holes per battery charge.
The higher efficiency of the brushless motor, combines with the super charge capacity of the 5.0Ah batteries to deliver what one vendor describes as unbeatable runtime.

In addition to “class-leading performance,” Dewalt says that their new cordless brushless rotary hammers offer “the lowest vibration level in the category.”
There’s no word yet as to whether these will be released in the USA, but if they are, then they will probably be announced at the 2015 World of Concrete show in early February.
The new brushless rotary hammers are welcome additions to the 18V XR/20V Max cordless lineup, and a few comments in our “are you happy with Dewalt’s 20V Max progress post” suggest that we’re likely to see more brushless developments in coming months.
