Core Drills

Mayco and Multiquip core drills are powerful tools used in concrete, masonry, and asphalt drilling applications, delivering precision and performance on demanding job sites. Because these machines operate under intense pressure and abrasive conditions, key components inevitably wear over time. Having access to the right core drill repair parts is essential for maintaining performance, reducing downtime, and extending the life of your equipment. Genuine Mayco/Multiquip replacement parts are engineered to meet original manufacturer specifications for durability and compatibility. Common repair parts include diamond drill bits and coring bits, bearings and seals, water swivel assemblies, drive shafts, pulleys and belts, spindle and chuck components, and motors or electrical switches. Diamond coring bits are subject to the most wear and must be matched correctly to the material and hole diameter for optimal cutting life. Bearings and seals help support smooth rotation and protect internal mechanisms, while water swivel parts ensure proper cooling and dust control during drilling. When sourcing parts, always reference your core drill’s model and serial number to confirm a precise match. Many reputable suppliers offer exploded diagrams, part numbers, and detailed listings to help you quickly identify the correct components. With quality repair parts and proper maintenance, your Mayco/Multiquip core drill will continue to deliver reliable performance, accuracy, and productivity for every job.
