Bosch grinding wheel uses aluminum oxide as the abrasive material and has a diameter of 5 in. Bosch incorporates this aluminum oxide material into the grinding wheel forming a grit of 30. The arbor attachment allows for easy mounting to the tool or pad. In addition to the other aspects of these parts, another important component of these is the thickness. This Bosch part is 1/4 in thick.
Specification parameters description:
Grit:
Grit is a measurement of the size of abrasive particles embedded in coated abrasives. The most common standards for grit size are the United States CAMI (Coated Abrasive Manufacturers Institute) and the European FEPA (Federation of European Producers of Abrasives). A smaller grit number means larger particles and a coarser grade, while high number grits are used for finer work. Grit is generally a unitless measure but is sometimes measured in microns.
System..Abrasive Material:
Aluminum Oxide Aluminum oxide is an artificial abrasive suited for general purpose stock removal and finishing. It is the mostly commonly used abrasive and can be used for most steels and ferrous alloys. Aluminum oxide is slightly softer but tougher than silicon carbide.
System..Attachment Type:
Arbor Arbor mounted items have a center hole and are designed to be used with shanks or mandrels, sold separately. The diameter of the center hole is provided to determine compatibility.
