Another vote for a Forstner bit here. I assume you are sinking holes for pegs or equivalent. Also think about making a jig to hold the angle if you are using a handheld drill. Nothing more than a hardwood block that has a bore of the right size. You can set it all up so the drill bottoms out on the jig at just the right depth of the hole.
Do note that a Forstner bit will NOT clear the chips all the way out of the hole the way a twist drill will. You will need to vacuum chips out, possibly as you drill. You can add a vacuum port to your jig if you want to get fancy. They also produce larger chips than a twist drill, so be prepared for that.
Oh, and the cheap Harbor Freight bits will work, but get dull pretty fast.
