Before ordering
Confirm opening size and workpiece thickness, then match the cup with a compatible arbor, pilot and drill. The listing's universal-arbor wording does not establish fit with every arbor you own. Follow the manufacturer's guidance for the actual material, including embedded fasteners if present.
Product questions and answers
Does the cup come with an arbor?
No. The arbor is explicitly listed as sold separately. Check the compatible connection before ordering.
Is 3-5/8 inches the cutting depth?
No. It identifies hole diameter. Cutting depth is separately listed as 1-1/2 inches.
Is the entire saw made from 8% cobalt HSS?
No. That specification refers to the teeth; they are joined to a separate alloy body in the bi-metal construction.
