The Ingersoll Rand 307b air die grinder forms the basis of this product kit. As a straight die grinder, the tool’s grinding head is in line with the body. This lets users reach areas and openings that don’t offer enough room for angle grinder wheels. This air die grinder is ideal for medium duty deburring, polishing, porting, smoothing edges, and weld grinding.
