Diamond core drills are used to cut clean, round holes in hard materials like concrete, brick, and cement board. They’re widely used in construction and installation work, especially for plumbing, wiring, and HVAC systems. Compared to traditional drills, they cut more smoothly with less noise and vibration.

The KYNKO KD49 is a professional-grade tool built for tough jobs. With strong power, advanced motor technology, and a durable design, it offers reliable performance and a long working life—even under heavy-duty conditions.

Strong Motor, Built to Last

KD49 is a 4600W high-performance motor made with advanced manufacturing technology. It delivers strong torque to drill large holes with ease. Thanks to KYNKO's patented motor coating technology, the motor stays cooler and lasts longer—even during extended heavy-duty work. Unlike many other drills, the KD49 is designed not to burn out under pressure.

Durable Gear System and Housing

Inside, the drill uses a 20CrMnTi alloy steel gear system, known for reducing noise and greatly improving durability. The gearbox is made with reinforced materials that handle high torque better and last longer than standard models.

The KD49 also features a thicker housing than most competitors, providing extra protection and a longer service life on tough job sites.
