 Different type of diamond segments for core bit: 
Diamond Segments

• All our diamond segments have well designed bond systems combined with high concentrations of top quality synthetic diamonds to provide trouble-free drilling through a variety of applications
• Segments type:1)crown type; 2) turbo type; 3)roof type 4)straight type for you choose.

Steel Barrel

• All our barrels are made using top quality steel and are guaranteed to run true

For diameters 10mm to 38mm we use high quality 10mm high quality crown (ring) diamond segments - This helps for an easy start-up when hand held drilling.For diameters 40mm to 500mm we use high quality 10mm high diamond segments with castellated tips to insure an easy start-up and fast opening of the segment.Usually customers will choosing the thread of 1-1/4-7.
