The Makita XRH10ZW is the wet-drilling variant of the XRH10Z high-energy 36V LXT X2 SDS-Max rotary hammer, configured for water-cooled diamond core drilling through reinforced concrete. With 8.1 ft-lbs of impact energy and a 2 in. concrete capacity, it handles the large-diameter penetrations required by mechanical, plumbing, and electrical contractors drilling sleeve openings. Sold tool-only for LXT X2 platform users.
What is wet drilling and why is it used with the XRH10ZW?
Wet drilling uses a continuous water supply to cool diamond core bits during coring operations. Water extends diamond bit life, reduces heat distortion, suppresses silica dust at the source, and improves cut quality through reinforced concrete. The XRH10ZW includes a water swivel or provision to connect a water feed directly to the core bit.
Can the XRH10ZW also be used dry without water?
Yes. The wet drilling attachment is a functional addition, not a limitation. The XRH10ZW can operate as a standard rotary hammer for all dry drilling and chipping tasks when the water feed is disconnected.
What diameter core bits are used with wet coring on the XRH10ZW?
Wet SDS-Max diamond core bits from 1 in. to 4 in. diameter are typical for plumbing sleeve and conduit penetrations through reinforced concrete walls and slabs. Larger diameters require a dedicated stand-mounted core drill.
Do I need a water pump to use the wet drilling feature?
A gravity-fed water bottle setup or a pressurized water supply can both work. Makita and third-party manufacturers offer accessory water feed kits for SDS-Max wet coring. For sustained production coring, a small submersible pump in a water bucket is the most practical approach.
What is the difference between XRH10ZW and XRH12ZW?
Both are wet-drilling SDS-Max tool-only variants with wet coring capability, but they belong to different model families with potentially different power levels and body configurations. The XRH10ZW is the heavier, higher-energy 2 in. variant (8.1 ft-lbs), while the XRH12ZW is in the XRH12 family rated at 1-9/16 in. capacity.
