21V PlatformBrushless Pure Copper MotorConcrete Φ26mmCE EMC CertifiedDocking Charger
The Geakita RH-02 is a 21V cordless rotary hammer designed for concrete, steel and wood drilling across construction sites, workshops and installation work. A brushless pure copper motor delivers 0–2000 r/min no-load speed with 0–4500 min impact frequency, while the 2000mAh x 10-cell battery pack and docking charger shorten turnaround between tasks. One tool covers anchoring, fixing, maintenance and fit-out work: up to Φ26mm in concrete, Φ13mm in steel and Φ26mm in wood.
Product Summary
The RH-02 combines a brushless pure copper motor, a 21V lithium battery platform and a docking charger in a single handheld rotary hammer. It is built for buyers who need one cordless platform to handle concrete drilling, metal cutting and bolt fastening, vehicle maintenance, and wood drilling on production or fit-out jobs. Housing, structural and conductive parts use ABS, aluminum alloy, steel and copper. The model is supplied to power tool distributors, hardware stores, construction contractors and OEM/ODM partners.

Models and Options
The rotary hammer is offered under model RH-02 on the 21V battery platform. Buyers can plan around a single battery and charger system for repeat orders. OEM/ODM programs are available for distributors, hardware chains and tool brands that need their own configuration, branding or packaging.
Materials and Structure
The RH-02 uses ABS for the outer housing, aluminum alloy for structural components, steel for load-bearing parts and copper in the motor and electrical system. This material mix supports a handheld form factor while keeping the tool rigid enough for hammer drilling. The 21V battery pack docks into the tool body, and the docking charger keeps packs ready between shifts.
Applications
The RH-02 fits four main buying segments:
- Power tools industry – platform tool for distributors and tool brands.
- Construction industry – concrete and masonry drilling, anchoring and fixing.
- Hardware tools industry – counter and shelf sales alongside drill bits and accessories.
- Maintenance and installation industry – metal drilling, bolt fastening, vehicle maintenance and workshop repair.
Its drilling range covers Φ26mm concrete, Φ13mm steel and Φ26mm wood, so it suits both site work and fixed installation tasks.
