Adjustable Core Pulling Pliers, Mechanical Leverage Core Remover Tool, Heavy‑Duty Steel Hole Debris Extractor for 50‑200mm Drill Holes, One‑Hand Lifting for Construction Drilling Work

✅ Mechanical Leverage Self‑Tightening Structure Built‑in leverage principle delivers automatic self‑locking grip. The heavier the stuck concrete core or drilling debris, the tighter the jaws clamp. Effectively prevents slipping during lifting, easily pulls stuck core samples out from deep drill holes. ✅ Fully Adjustable Jaw Opening, Wide Compatibility Multi‑hole position‑adjustment design lets you modify jaw span freely. Works for borehole diameters ranging from 50 mm to 200 mm. For holes ≥120 mm, the pliers can go deep inside the hole to grab and extract embedded core waste. ✅ Heavy‑Duty Integrated Tool‑Steel Build Widened thickened high‑quality tool steel, one‑piece forming with no welding seams. High strength, wear‑resistant and deformation‑proof for long‑term construction‑site use. Smooth polished non‑slip jaw surface for stable grabbing. ✅ Simple Single‑Rope One‑Hand Operation Equipped with durable red lifting rope. Just drop the tool into the drilled hole, hook onto the core sample and pull upward with one hand. Fast labor‑saving extraction, no extra complicated equipment required. Lightweight and easy to carry to job sites. ✅ Practical Helper For Drilling & Construction Workers Perfect for pulling concrete core samples and stuck hole debris after core‑drilling. Eliminates the frustrating problem of trapped waste that cannot be taken out. Ideal for drill technicians, renovation crews and general construction projects.
