POLYCRYSTALLINE DIAMOND

Brown Diamond Tools manufactures a complete range of high quality Sintered Diamond tipped tools, Inserts, Reamers etc. Our Polycrystalline Diamond (PCD) blanks are used for Turning, Grooving, Milling & Boring operations on a wide variety of non ferrous and non metallic materials.

ADVANTAGES OF USING BDT - POLYCRYSTALLINE DIAMOND (PCD)

	Higher material removal rates, improved cycle times, providing more parts per shift
	Significantly faster cutting speeds and feed rates compared to conventional cutting tools
	Highly improved workpiece quality, excellent dimensional control, consistent surface finishes, reduced scrap
	Longer tool life resulting in increased machine up-time, providing greater production capacity without investing in new equipment
