6 Inch Aluminum Lap Base Plate

Diameter: 6 inch (150 mm), arbor hole: 1/2 inch (12.7 mm). Made from lightweight yet rigid aluminum with smooth surface finish and precise concentricity. Designed exclusively as a backing plate for diamond-coated flat lap disks — not a grinding tool itself. Edges are softly chamfered for safe, comfortable handling during installation and operation. Compatible only with machines accepting 1/2-inch arbor shafts and requiring a rigid, flat mounting surface for diamond lap wheels. Note: Diamond-coated grinding disks are not included and must be purchased separately.
