These larger carbide core bits also come in two types with a pilot drill bit and a guide pin/plate version. Our personal preference is the guide pin/plate set up because weâve gotten the remaining cut concrete jammed in the bit a few to many times.ith the dry diamond core bit (up to 6â) in this setup the bit grinds the concrete, not pounding it like a hammer drill so the holes will actually be much cleaner with less chance of blowout on the backside.
TurboTax FAQ. TurboTax can save your tax return as a tax data file (also called a tax file, data file, or a .tax file) and as a Portable Document Format or PDF file.
Each year's program can only open that year's files directly, but they can also import data from earlier years' files in order to carry over figures as appropriate. (And they can import past-year data from the competing TurboTax program as well.) The format is a proprietary binary format. Bytes 05 and 06 (where the first byte is 00) appear to contain the year the tax return is for as a 16-bit little-endian integer. H&R Block at Home official site.
