About these items:High-Performance Motor: Equipped with a powerful 1450W copper motor, these electric magnetic drills deliver robust torque, supporting coring drill diameters up to 2" (50mm) and twist drills up to 0.6" (16mm) with a maximum speed of 800 RPM, ensuring efficient and precise drilling even in the toughest materials.Exceptional Magnetic Force: The MDP-50 model generates a magnetic force of 2878 lbf (12800N), while the ZT-45H model offers 2810 lbf (12500N), providing exceptional stability for secure operation at any angle, reducing vibration and improving accuracy.Precision and Durability: Designed with a titanium magnesium alloy guide rail for superior corrosion resistance and longevity. Both models include precise scale markings on the machine frame, enabling accurate depth control and easy alignment for professional results.Enhanced Safety Features: Integrated overload protection and efficient cooling systems prevent overheating, safeguarding operators from sudden power surges and maintaining long-term performance without interruption.Versatile Applications: Ideal for steel fabrication, industrial manufacturing, ship and bridge building, windmill and power plant construction, and heavy equipment maintenance. Suitable for use on steel plates with a minimum thickness of 0.39" (10mm). Not compatible with stainless steel or cast iron.Key Differences:Model: MDP-50 vs. ZT-45HMagnetic Force: 2878 lbf / 12800 N (MDP-50) vs. 2810 lbf / 12500 N (ZT-45H)Max.
