Dewalt has announced two new FlexVolt 60V Max SDS Max combination rotary hammers in 1-7/8″ and 2″ sizes.

Both of the new FlexVolt rotary hammers are said to be ideal pairings for Dewalt’s new FlexVolt 15Ah battery that was also recently announced.

Dewalt DCH735 FlexVolt Rotary Hammer (1-7/8″)

Both of the new Dewalt brushless rotary hammers offer fast concrete drilling for use in a wide range of applications.

The DCH735 rotary hammer delivers 13.3 Joules of impact energy, and is described as a midweight tool.

It’s said to be well suited for tasks such as horizontal and downwards drilling for #6 through #9 rebar dowel operations, dry core drilling of up to 5″, chipping tasks, driving ground rods, and bushing.

Price: $999 for the DCH735X2 kit
ETA: September 2021

Dewalt DCH775X2 Rotary Hammer

The new Dewalt 2″ cordless rotary hammer, also featuring a brushless motor, delivers 19.4 Joules of impact energy.

It can handle horizontal and downward drilling for #9 through #14 rebar dowel applications, dry coring up to 6″, as well as chipping, ground rod driving, and bushing operations.

Shared Rotary Hammer Features

Both tools are part of Dewalt’s PERFORM & PROTECT product line, featuring:

Anti-Rotation E-Clutch System that shuts down the tools when they detect bind-up situations.

SHOCKS Active Vibration Control that reduces vibrations felt by users at the handle.

Both tools also have:

Wireless Tool Control – this allows users to link the tools to the Dewalt FlexVolt DCV585 dust extractor for remote activation.

Tool Connect Tag-Ready – add a tag accessory (sold separately) for tracking via the Dewalt Site Manager app.

OSHA Table 1 Complaint – silica dust control compliance is achieved when used with either DWH050 or DWH053 shrouds and the DCV585 dust extractor. The shrouds and vacuum are sold separately.


Dewalt has existing FlexVolt 60V Max rotary hammers, DCH733 and DCH773 DS Max combination rotary hammers, 1-7/8″ and 2″ models, respectively, and it will be interesting to see how these new offerings compare.

That the new FlexVolt rotary hammers were announced alongside the also-new 15Ah battery, suggesting that they were designed to drive deeper (pun not intended) into higher performing tool territory.
