• Best For: Six-inch 5/8-inch-spindle wet saws slicing thin slabs or trimming glass, where a narrow kerf protects material yield.
• Highlight: MK lists the 5/8-inch bore at the same price as the 1/2-inch in this specification, so the choice comes down to the saw rather than to cost.
• Expert Note: If the spindle measures 1/2 inch, part 153691 is the same 6-inch .020 MK-303 in that bore - identical rim, identical kerf.
