Metal Bond Diamond Core Drills made with our exclusive metal bond developed for high strength and longevity. Working with Quartz, Ceramics and many man-made modern materials require special design, especially when drilling straight clean holes. Chipping cracking, drill burn-out and excessive wear will occur unless great care is taken. Our diamond drill sizes range from .026" to 36.000" diameter with tolerance of (±.0005") on 2" and under on ID or OD. We have the ability to mount core drills to your needs or the standard that is used at your facility
Braemar manufactures Metal Bond Diamond Core Drills with natural or synthetic diamonds, sieved to the desired grit size, mixed with a metal matrix and sintered to a steel core. The depth of diamond is usually 1/4", or 3/8", other depth sizes can be made upon request. The standard wall thickness on drills that are 3” and smaller is 0.030”. Most of our drills are made with synthetic diamonds that are uniform in grit, shape, and size: than natural diamonds. Diamond size can range from 20/30 to 270/320 grit. Coarser grit sizes are used for faster stock removal without much concern for surface finish.
