A quick google will give you a conversion chart. They do also sell them in standard sizes like 3/32 or 1/4, but you may have to contact ATS directly. **Q: Although this seems to be used for rivets on aircraft, can it also be used on solid aluminum and steel millwork projects for flat head machine screws?** A: Hello, Unfortunately this item will not work for the purpose you are proposing. These pilot cutters are 100 degree 3 flute cutting edge and I believe if you are using AN screws they will require a 82 degree cutter which we do not sell. **Q: What is the Thread size of the cutter's shank? (IE 1/4-28 ?)** A: It looks like 1/4" 28. I don't have any fine thread nuts around. It catches the first thread on 1/4 20 but won't go any further. **Q: Is it 60 degrees or, like most countersinks, 80 degrees? They don't say in the description.** A: 100 degree counter sinks -- for standard aviation rivets AD426-xxxx ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by C***S on November 8, 2025* ### ⭐⭐⭐⭐⭐ Review *by B***Y on January 31, 2024* ### ⭐⭐⭐⭐⭐ Review *by J***D on December 14, 2021* ## Frequently Bought Together - Aircraft Tool Supply Countersink Kit W/Pilot Cutter - 86 Piece Cleco Fastener Deluxe Kit- Cleco Fasteners, Clamps, and Pliers - Air Capital Hole Finder Kit - 5-Pc.
