Diamond Core Drills

Braemar USA Diamond Core Drills are engineered for precision drilling in sapphire, quartz, ceramics, glass, and a full range of advanced technical materials. Manufactured using premium synthetic diamond and carefully formulated bond systems, these drills deliver clean entry, minimal chipping, and exceptional dimensional accuracy for production machining, R&D facilities, and high-precision manufacturing environments. Designed for CNC spindles, ultrasonic drilling systems, and manual high-speed equipment, BGSUSA core drills maintain sharp cutting action, fast material removal rates, and long tool life—even when cutting the world’s hardest and most brittle substrates. High-performance construction includes premium diamond concentration for aggressive, stable cutting; optimized bond hardness for long life in abrasives like sapphire and fused quartz; and uniform diamond exposure that ensures consistent hole sizing and superior edge quality. Offered in thin-wall, standard, and heavy-duty geometries, these drills excel across sapphire optics, fused quartz and fused silica, alumina and zirconia ceramics, MACOR®, technical glass, borosilicate, silicon carbide, ferrites, composites, and other specialty materials. Precision engineering ensures true-running diamond tips that reduce vibration and micro-cracking, controlled coolant flow for improved chip evacuation, and tight manufacturing tolerances that guarantee repeatable results in high-value production environments. Ideal for optics manufacturing, semiconductor processing, medical device machining, aerospace materials, and advanced research applications, Braemar Diamond Core Drills deliver the reliability, accuracy, and durability required for modern precision manufacturing—producing clean, accurate holes with long, stable tool life across demanding applications.
