What drill is drilled after quenching?
Carbide coated tools can handle around HRC50 of materials, such as Mount Vickers 840, and material 1220.
Quenching: a heat treatment process for quenching of metals and glass. Steel the steel quenching is heated to the critical temperature Ac3 (hyposteel) or Ac1 (hypereutectoid steel) above the temperature, holding time, so that all or part of 1 Austenitic, then the cooling rate is greater than the critical cooling rate of fast cooling to below Ms (or near Ms ISOTHERMAL MARTENSITE () or bainite) heat treatment process transformation. Aluminum alloys, copper alloys, titanium alloys, tempered glass and other materials are usually treated by solid solution or heat treatment with rapid cooling process.
