Q&A

Please note, Aircraft Spruce's personnel are not certified aircraft mechanics and can only provide general support and ideas, which should not be relied upon or implemented in lieu of consulting an A&P or other qualified technician. Aircraft Spruce assumes no responsibility or liability for any issue or problem which may arise from any repair, modification or other work done from this knowledge base. Any product eligibility information provided here is based on general application guides and we recommend always referring to your specific aircraft parts manual, the parts manufacturer or consulting with a qualified mechanic.

Q: Do both 3/8" and 1/2" inch diameter counter sinks fit in the micro-stop?

Per the supplier: Yes, 12-00879 would be the correct size cutter for 3/8" and 1/2".

Q: Can I use these Micro-Stop countersinks with 4130 steel?

Per the supplier: yes, it can work on 4130 steel, but it will wear out the cutter a bit more than what it is designed for (aluminum). We also suggest to use some type of lubricant for the 4130.

Q: How do these products work with lexan?

These are designed for aluminum. They might work with lexan but we recommend trying it on scrap first to may sure.
