Handheld Rotary Well Drilling Machine

It's a small electric drilling machine intended for household and light commercial use: drilling family wells, factory wells, irrigation wells, installing water/air-conditioning systems and solar water heaters, small piling jobs, and similar tasks where holes 50–200 mm diameter are required.

The machine uses a single‑phase 220 V motor (standard household supply in many countries). The motor has adjustable speed and can run in reverse. For other voltages or export versions, consult the supplier.

The product literature mentions drilling diameters from 50 to 200 mm. Depth information varies in the description (40 m is listed in parameters while other text mentions up to 80 m). Actual maximum depth depends on model and drill‑pipe configuration—please confirm the specific model's rating with the seller before purchase.

The whole drilling head weighs about 8 kg, making it relatively easy to carry and suitable for handheld or small‑crew operation. Additional drill pipes and accessories add weight for deeper drilling.

Factory shipments typically include two steel drill bits (6.5 cm each). Drill pipes are usually sold separately; the standard drill pipe diameter is 32 mm and each section is about 1.8 m long. Contact customer service for exact packing lists and prices.

Yes. Depth is increased by adding drill‑pipe sections (each ≈1.8 m). The exact achievable depth depends on the number of sections used and the model's power/torque limits. Ask the supplier for recommended configurations for deeper wells.

The multi‑gear transmission provides several speed/torque ranges, allowing better control over drilling speed and torque for different ground conditions. It makes drilling easier to manage (more torque at low speeds and higher speeds when appropriate) compared with a single‑gear design.

The disc (rotary head) design allows the operator to freely rotate and position the drill without damaging the drill head or casing. It improves handling and helps prevent scratches or damage to the machine and drilling components during operation.

Wear appropriate PPE (gloves, eye and ear protection), secure the machine before drilling, ensure proper grounding and avoid wet electrical conditions, keep bystanders clear, never exceed the rated depth/torque, and use correct drill bits and pipes. Read the operator manual and, if inexperienced, get trained or supervised by someone experienced.

Select drill‑bit diameter based on desired well diameter (50–200 mm supported). Use the recommended 32 mm drill pipe sections for the standard configuration. Match bit type to soil/rock conditions (cutting, auger, or rock bits) and consult the supplier for bit selection and availability of special bits.

This handheld rotary machine is optimized for shallow to moderate depth drilling and softer ground or mixed conditions common to household and small agricultural wells. For hard, continuous rock or very deep commercial drilling, a purpose‑built heavy rig or specialized rock bits and techniques may be required. Consult the supplier about available bit types and any model upgrades for harder formations.

Yes. The description states that special specifications can be customized. Contact customer service with your required depth, diameter, voltage, or other needs to discuss custom options, lead times, and pricing.

Routine maintenance includes keeping the gearbox and couplings lubricated, checking electrical connections, inspecting drill pipes and bits for wear, and replacing worn seals or brushes per the manual. Spare drill bits, drill‑pipe sections, and common wear parts should be available from the manufacturer or dealer—confirm warranty and spare‑parts support before purchase.

Use the reversible motor function to try backing the bit out slowly. Reduce torque and reverse rotation to free stuck bits. If that fails, stop the machine, stabilize the string, and manually remove or disassemble as recommended in the manual. Avoid applying excessive force to prevent damage. If unsure, contact technical support.

Warranty terms and after‑sales support are not specified in the product text. Ask the seller for warranty duration, coverage details, available service centers, and spare parts availability before purchasing.
