Original Oubao 14 Inch Core Drilling Machine OB-355

Original Oubao 14 inch core drilling machine for reinforced concrete, stone, granite and marble. It runs every bit size from ½ inch up to 14 inch (355 mm) with high stability on its stand. Equipped with a Safety Clutch that instantly disengages the drive if the bit suddenly jams under overload – protecting the operator from accidents and the motor from burning out.

Technical Specifications

Who is this machine for?

For core drilling companies and contractors who cut large openings in reinforced concrete (drainage pipes, ventilation ducts, columns, large rebar anchoring) and need high power with steady torque at large diameters.

Important notes before you buy

• The machine comes on its own in a sealed box without core bits; bits are bought separately in the sizes you need.
• The machine size (e.g. 8 inch) means it runs every bit size from ½ inch up to 8 inch.
• In core drilling, one inch = 25.4 mm, which is different from the plumbing inch.
• Light or moderate workload: original Oubao is the best value for money. Heavy daily core drilling: original Cayken is built from higher-grade materials.
