CHASE DIAMOND TOOLS LTD., established in Hatton Garden in London in 1965, grew to become the leading supplier of single crystal diamond tools in the U.K. In the 70s the Diamond polishing function was re- located in Sandy along with a new engineering company Chase Precision. This company produced high specification manual and fully automatic contact lens machines. Hatton Garden offices were used as the companies headquarters. Both companies were heavy involved in the contact lens and IOL industries in the 1980s through to the 90s. In the late 80s Chase Diamond relocated to its own factory in Peterborough, making room for expansion of the engineering side in Sandy, Bedfordshire. In 1992 Chase Diamond Tools was purchased by Kevin Stokes from the previous owners and became Chase Diamond Tools International Ltd. In the spring of 2001 Chase was moved to a larger purpose built facility on the outskirts of Corby in Northamptonshire. From this facility we run our European Repair Centre, Small batch production, Research and Development and training centre.
