Frequently Asked Questions About Our Ground Drilling Machines

Q: What advantages does your Model‑350 frame‑type spiral pile driver have compared with similar products from other manufacturers?

A:The drill pipe is made of alloy manganese steel with a thickened profile, and can be customized to various thicknesses as per customer requirements. The drill bit offers three configurations: three-blade alloy,alloy tooth, or impact drill tip. Many similar products on the market have fixed pipe dimensions and thickness, lacking customization options.

Q: I have some concerns that the gears may get damaged easily.

A:Please rest assured.The gear in the LeiLi gearbox is crafted from high-strength alloy steel.offering impact resistance and wear resistance. It minimizes tooth damage during high-resistance drilling operations. The high-torque design ensures powerful force when using large-diameter, deep-drilling bits. The gearbox features meticulous eraftsmanship and a sleek, aesthetically pleasing appearance!

Q:The geological condition at my site is challenging, with small stones mixed in the soil. Can your equipment complete the hole‑drilling work?

A:Certainly.hard soil, soft soil, and soil mixed with stones can all be processed.The alloy drill tip ensures precise positioning, and the alloy blade effectively removes small stones and tree roots embedded in the soil, allowing them to be dislodged along with the rotation of the spiral blade.

Q:Which model do you recommend for single‑person operation?

A:We would like to recommend our small-frame dual-wheel gasoline-powered auger drill.High efficiency and labor-saving: Featuring foot-operated pressure application and two-stroke gasoline engine, it completes hundreds of holes per person per day with minimal time per hole, significantly reducing labor costs.

Q:What other advantages does this model have?

A:Featuring an equidistant spiral pattern with pitch optimized for drilling speed, it rapidly expels soil and gravel through the blade during drilling, preventing slag accumulation and effectively avoiding issues like drill jamming or machine clogging. This design guarantees continuous drilling operations, with single-hole completion speed exceeding conventional straight rods by over 100%.

Q: Which product should I choose for drilling holes of 500 mm diameter and 10‑meter depth?

A:We recommend our Model‑350 frame‑type spiral pile driver. Its drilling diameter ranges from 40 mm to 600 mm, and drilling depth from 0 m to 12 m, which can satisfy your requirements.
