Saws are carbon steel Morse brand and made in the USA. For Use On Aluminum, Brass, Bronze, Plastic, Stainless Steel, Steel, and Wood. I get them here in Nj at a machine tool supply at screaming deal.
saws 1-1/4 and larger have a 5/8-18 thread I have 1/2-5/8 adapters so you can run all the saws on the same arbor. If you but the pilot drill I include the adapter as a set.
Don't get ripped off at Home Depot at 2x the price. These are razor sharp and I use them all the time.
Arbors are also Morse USA made units.
1/2-20 with 5/8-18 adapter
5/8 -18 snap back quick release this one is spring loaded, and you just pull up. It can't over tighten or fall apart like the Lennox detent style.
This is how we can support US manufacturing and business, at the ground level.
