Fowler Full Warranty 52-760-000-0 Hardness Tester File Set, 0.157" Diameter, 7" Length, Set of 6 Files

Fowler Full Warranty 52-760-000-0 Hardness Tester File Set,

The Fowler 52-760-000-0 Fowler's Hardness Tester File Set is an inexpensive, easy-to-use method for determining material hardness by sliding the file across the object's surface. Six color coded files indicate hardness from 40 to 65 HRC. Conveniently packaged in a leath­er-like case with a velcro lined flap, the files are approximately .157" in diameter and 7" in length (4.3Ø x 175mm).   Testing Procedure: * Run the Black file (65 HRC) over test material. If it marks the material, the material is less than 65 HRC. * Try the Blue file (60 HRC). If it does not mark the material, it indicates that the file is softer than the material and is between 60 and 65 HRC. * If the Blue file (60 HRC) marked the material, continue testing with the Green (55 HRC), Light-Green (50 HRC), etc. until the material is not marked. The approximate hardness of the material is between the file that marks the material and the file that slides over the material. * Included chart also shows the appropriate Vickers Hardness (HV).     Color Indication File Hardness Red 40 HRC 40-42 HRC 392-412 HV Yellow 45 HRC 45-47 HRC 446-471 HV Light Green 50 HRC 50-52 HRC 513-544 HV Green 55 HRC 55-57 HRC 595-633 HV Blue 60 HRC 60-62 HRC 697-746 HV Black 65 HRC ...

Deluxe Mohs' Hardness Pick Set for Mineral Identification, Wooden Case

Deluxe Mohs' Hardness Pick Set for Mineral Identification,

Hardness is an important and quantifiable physical characteristic of a mineral and in your effort to identify an unknown mineral, the hardness, if known, combined with other properties, can narrow your search to just a handful of possibilities. Simply scratch a smooth surface of your unknown mineral with the picks of various indicated hardness. As an example, if a No. 5 pick scratches the mineral, but a No. 4 pick does not, then your mineral hardness is 4.5. Then compare this against a table of minerals listing hardness values to aid in identifying the unknown mineral. The Deluxe Hardness Pick Set from Mineralab is unique in that, unlike other mineral hardness test tool that use minerals or crystal points, Mineralab picks are made of metals and alloys of hardness values equal to 2 through 9 on Mohs hardness scale. Because the picks are made of metal, they are easily ground to sharp points which will not break off and which can be easily sharpened. Included in the Mineralab's Deluxe Hardness Pick Set: * Four double-ended picks with eight points comprising 2 and 3, 4 and 5, 6 and 7, 8 and 9 on Mohs' hardness scale. * High quality brass pinch vises. * A glass plate (hardness of about 5.5) which, when scratched, quickly distinguishes hard from soft minerals. * A second hardness plate...
