Rockwell Hardness Testing File Sets
Set includes six files and a chart to convert to Vickers scale. It is an economical way to determine the hardness of steel on the Rockwell C-scale. Handles are marked with Rockwell hardness values. If a file can scratch your material, then your material is softer than the file. If a file cannot scratch your material, then your material is harder than the file.

Rockwell Hardness Calibration Test Blocks
Make sure your hardness testers are accurately calibrated. Blocks are marked with their corresponding Rockwell hardness and a serial number.
All blocks come with a calibration certificate traceable to NIST that states they've passed a test for accuracy.
Pressure-Grip Rockwell Hardness Testers
Operate these testers with one hand. Squeeze the handles until the penetrator contacts the test material and a reading appears on the dial indicator.

Rockwell Hardness Testers
This tester uses an indenter to measure the hardness of aluminum, brass, and steel. It can be used at any angle without affecting accuracy.
For heat-treated material harder than Rockwell C20, use the optional C-scale diamond indenter.

Brinell Hardness Testers
Determine the hardness of very hard steel. To use, slide a test bar into the tester, place the tester on your surface, and hit with a hammer; a steel ball will make an impression. Measure the impression with the 20X microscope and use the computing disc to determine hardness.
