      APPLICATION: (materials used on)       

SMART CUT™ series Micro Diamond Drills provide the most 

precision performance on  Alumina, Glass,  Quartz,  

Ruby, Sapphire,  Yag,  Silicon,  Fused 

Quartz,  Bk7,  and Many Other Materials.

Diamond Micro Drills are Manufactured in clean room environment under the Highest Quality Standards to Mil Specs. Only the highest quality raw materials are used in manufacturing process. Utilizing world class quality control, inspection, and measurement equipment. Highly Experienced Engineers and chemists constantly monitor and control all material input & output at all stages of manufacturing process. Insuring product consistency for use in demanding & sensitive applications such Nano Technology, MEMS, Materials Research, and etc. Customers include some of the Leading Fortune 500 companies, Universities, Military, Space Flight Organizations, Laboratories, Advanced Material Fabricating Facilities to small machine shops. Diamond & CBN (cubic boron nitride) is the hardest material known to man and is well suited for drilling all types of materials harder than 35 Rockwell scale C.

Diamond Micro Drills grind away material on micro (nano) level. Diamond & CBN Micro Drills will machine hardest material, including those materials that other conventional micro drills, such as carbide and high speed steel will not. Diamond Micro Drills will drill harder materials materials faster, produce smoothest possible surface finish quality, preserve material micro structure, drill greater depths, and provide consistent performance, & yield (cost per part)
