CleanBreak™ pliers (CWBR-200) are a useful tool for cleaving samples, post scribe, from full wafers down to 20 mm pieces. The pliers come with two styles of jaws to cleave a wide variety of substances:

  • Two sets of Three-Point Jaws, for cleaving crystalline substrates. These jaws cleave by providing pressure on the sample underneath the scribe and two pressure points on top of the sample, equidistance from the scribe.
  • Flat metal jaws for glass and ceramics

Pliers are made of lightweight yet rugged plastic with an 8″ (203mm) handle and 0.9″ (23mm) jaw opening. Typically used for thick glass and hard materials such as sapphire.

For samples smaller than 30mm, please also see Small Sample Cleaving Pliers or Small Sample Cleaver
