## Description

The Aircraft Tool Supply Countersink Kit is a professional-grade tool designed to create clean, precise countersunk holes in various materials. The included pilot cutter ensures accurate starting points for drilling and countersinking.

Review: Excellent quality - This is a good quality tool that will last a lifetime if you take care of it. Not cheap, but definitely worth every penny.
Review: Exact same Countersink as M A Ford - For a long time, M A Ford has made these fantastic precision aircraft countersinks. Great product, but their marketing & customer service is stuck in the 1980s, they are terrible to deal with; truly hopeless. I ordered this new countersink from Aircraft Tool; it is exactly the same part at about 1/3 what Ford was charging. The M A Ford countersinks with replaceable pilot pins are completely compatable with this countersink if you still use those, or the kit includes 4 countersinks. The teflon surface protector is radiused on the new one to minimize surface contact or scratching the target, and the thing runs very smooth & cool. CHANGING YOUR COUTERSINK WILL NOT CHANGE YOUR LIFE UNLESS YOUR LIFE INVOLVES COUNTERSINKING...this is a great product, very glad it is available from a normal company.

## Questions & Answers

**Q: what does the number stand-for for the countersink cutter? sometime is #40, #21, sometime is 1/4", I need 1/8" or 5/32", do you have?**
A: The number is standard drill size. #40 being slightly larger than 3/32" and #30 slightly larger than 1/8". 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
