A Brief History on the Development of Diamond Tools
November 12, 2019


The earliest naturally-occurring diamonds were discovered in India among alluvial deposits located in the country’s riverbeds.


Throughout history diamond has been prized for its quality as a precious gem, but diamonds have also found utility for a number of tooling applications – with the first recorded occurrence of diamond engraving tools used during 300 BC.



Industrial Applications of Diamond Tooling


It wasn’t until the mid-1700s that diamond would find additional industrial utility – with the development of diamond rock drills appearing in Diderot’s Encyclopedia, and diamond-tipped precision lathe tools patented by the English for diamond wire-drawing dye applications.


In the early 20th century, the first versions of diamond saw blades were manufactured to cut through architectural stone. It was also during this time that diamond grinding wheels were developed by fixing thick, circular metal wheels with diamond particles.



The Development of Synthetic Diamond


The development of synthetic diamond acted as the primary catalyst to the rapid transformation of industrial diamond tooling development. While the term “synthetic” offers the impression of imitation, synthetic diamonds are composed of the same pure crystallized carbon as naturally-occurring, natural diamonds. The only difference being that synthetic diamonds are produced through a controlled process.


Synthetic manufacturing of diamond became the focus of many research endeavors throughout the mid-20th century. This eventually lead to the two primary manufacturing methods of synthetic diamond today: High-Temperature High-Pressure (HTHP), and Chemical Vapour Deposition (CVD).



Diamond Tooling Today


The synthetic diamond manufacturing method of CVD is primarily used for the purpose of diamond tooling development today. Diamond offers a myriad of superior properties – making it perfect for machining, grinding, and cutting through abrasive materials. Diamonds high molar density have allowed for super-hardness, excellent heat conductivity, and high electrical resistance. Diamond also has the same friction coefficient as Teflon – which when combined with its property of hardness, makes for great use in coating wear parts that are more subject to sliding friction.


Today you’ll find a large range of diamond tooling available including diamond saw blades, diamond grinding wheels, diamond grinding pins, and more.
