9151 Precision Tri-Blocks (1-2-3 Blocks)
  • Made of high-quality, alloy steel, heat-treated to Rockwell “C” 63-65.
  • 1-2-3 blocks precision ground on all six sides to a uniform 8 micro inch finish or better.
  • Extremely accurate -- maximum error between any two blocks is 0.0001” on “Inspection” grade and 0.0002” on “Toolroom” grade.  Because of these unusually close tolerances, where “matched” sets are required, you need only order “Inspection” grade in whatever quantity is desired to make up a particular set.
