For electricians and plumbers working overhead or in tight spaces, the Makita HR140DSMJ delivers cordless rotary hammer performance in a compact 12V Max CXT package.

Why choose it

The brushless motor runs cooler and more efficiently, extending tool life and runtime. With two 4.0Ah batteries, you can keep working while one charges. The compact design and low weight reduce fatigue during overhead drilling, and the SDS-Plus chuck allows quick bit changes without tools.

Ideal use cases

• Drilling anchor holes in concrete, brick and masonry
• Installing electrical boxes and conduit in walls
• Light chipping and chiselling tasks (with appropriate bits)
• Rotary-only drilling in wood and steel

Good to know

The Makpac connector case stacks with other Makita cases for organised transport. The 12V Max CXT battery platform is shared with other Makita CXT tools, so batteries and chargers are interchangeable.
