Diamond Drill Bits and countersinks are diamond tools for glass hole drilling and countering.
They can also drill holes like ceramic, porcelain, stone, limestone, gemstones, marble, granite, slate, shell and bone. As well as agate drilling or core extraction.
Diamond Drill Bits include different shank types, such as straight shank, taper shank, internal and external threaded shank. Diamond-section wall thickness usually 1mm and height 10mm around.
Technology:
Taking high-quality steel as matrix, being formed through intermediate frequency hot pressing sintering.
Features:
Working in cooling water, high precision, sharp grinding, low noise, no tremor, no broken edge, high wear-resistance，high efficiency, long service life.
Operation Tips:
Step 1, Tilt 45 degrees first, drill a crescent shape.
Step 2, Drill in 90 degrees with water.
Step 3, Finish drilling smooth and beautiful hole.
ATTENTION:
1. After installation, adjust & observe whether it is beating, then normal operation
2. Smooth drilling, don’t apply lateral pressure and curve spud
3.Must add enough water for cooling and lubrication to reduce wear and coating off products
4. Dry drilling has big effects on working life.
5. The operator must wear safety protective equipment to ensure safe operation
