Hey all,
I have my 10" Delta drill press and a decent set of HSS bits that go up to 1/4". However, now I need to drill some 1" and 2" size holes in some 1/4" 6061 plate.
I bought a set of Harbor Freight el-cheapo-chinese forstner bits for a project (the Underwater ROV). They worked great for the plastic I was milling, but they have a million warning not to use them on metal.
So, how does one go about making larger round holes in Alum. when they only have a drill press?
