• 【Good Motor】Built with a pure copper motor, this machine delivers reliable power (4250W) and no load speed (500rpm), ensuring consistent performance even in demanding drilling tasks, making it the ideal choice for professional engineering projects.
• 【Well Designed】Its max drilling diameter can reach 10in, which can meet most of the air conditioning and pipeline drilling requirements. The hardened frame, thickened base with 4 screwed feet, and slip-avoid side handle can keep the drilling work stable.
• 【Adjustable Depth Control】Featuring a lifting handle and precise lifting rack, this drilling machine offers the flexibility to achieve precise drilling depths (deepest drill: 3.3ft, lifting height: 19.7in).
• 【Heat Dissipation】Multiple heat dissipation holes and the water pipe can make the product dissipate heat quickly, avoiding high temperatures and prolonging the service life of the concrete core drill machine.
• 【High Safety】The built-in mechanical safety clutch will not reverse and hurt people when hitting hard objects. The diamond core drill’s overload protection switch can automatically trip when the load is too large, to protect the motor from burning.
