BOLTR: Power-Fist Air Die Grinder.

In this teardown we'll have a look at a low cost pneumatic die grinder. The air vane motor inside is the powerplant that is in all rotary pneumatic tools. We also make a purpose built tachometer data logger incorporating the Rigol 1054 oscilloscope. We'll have a look at a few easy ways to improve air tool performance and maximize the capability of small workshop air compressors. Thank you to everybody that helped make this vid! www.Patreon.com/AvE Errata: The lower o-ring on the valve is HNBR. Thanks to xnutral for his technical expertise! From the parker website: HYDROGENATED NITRILE (HNBR, HSN) Hydrogenated nitrile was developed as an air-resistant variant of nitrile rubber. In HNBR, the carbon-carbon double bonds in the main polymer chain are saturated with hydrogen atoms in a process called “hydrogenation” that improves the material’s thermal stability and oxidation resistance.
