I don't know anything about your saw, but if you are cutting 3/4" and 1" hardwood you WILL be changing blades often even if it is Mahogany. Thick Hardwoods will eat up any blade. The best blade type for what you are doing is a skip tooth blade like Kevin said. To help with chipping use a reverse tooth blade. They are just like a skip tooth, but the last few teeth on the bottom are pointing up.
My blade recommendation for 3/4" to 1" hardwoods is Olson Reverse Tooth 5, 7 and 9, and Flying Dutchman Ultra Reverse 5, 7 and 9.
